Receiving

All precautions have been taken during loading and shipping to prevent shortages and damage to the equipment. It is, however, advisable that all received materials be carefully checked against the bill of lading (particularly ship loose components). Also inspect all materials for damage before and during unloading. Notify the shipping firm and Parkson Corporation immediately of any shortages, discrepancies or damage. Since the equipment is usually shipped F.O.B. Fort Lauderdale, it is the contractor's responsibility to make claims against the shipper for damaged equipment.

Handling and Transporting

When handling this equipment, care should be taken to avoid supporting or lifting in a manner that would place excessive stress on parts that are not designed to support the unit weight. This equipment should be moved only with lifting devices of sufficient capacity to handle the weight and size of the equipment.

Lifting and righting the equipment should be done only by the lifting eyes provided. Care should be taken not to damage any exterior protrusions and not to jar the equipment, which may damage internal components.

Storage

Should it be necessary to delay installation and subsequent operation of a unit for more than one month from date of shipment, special precautions must be taken. If possible, all equipment should be stored indoors. When no indoor storage space is available, the unit should be raised off the ground on skids and covered by a tarpaulin or equivalent protective covering. Never enclose the unit or components totally in plastic covers, always leave adequate admission of air to prevent condensation.

SECTION TWO

INSTALLATION

NOTE: Please refer to drawings.

NOTE: The Item Numbers on the General Arrangement Drawings are shown on the packing list in a column to the right of the page. These item numbers are also marked on tags attached to each item.

NOTE: IMPORTANT POINTS ARE IN BOLD TYPE AND UNDERLINED.

Installation of the filter is divided into four parts:

1. Installation of the drain manifold and bottom cones and filing below the bottom cones with concrete.

2. Installation of the feed assembly, feed manifold and support channels.

3. Installation of the remainder of the filter components.

4. Installation of sand media.

1. INSTALLATION OF DRAIN MANIFOLD, BOTTOM CONES AND CONCRETE FILL

A successful installation is impossible if the concrete basin does not have the correct elevations and dimensions. PLEASE TAKE GREAT CARE WITH STEP ‘A’ BELOW.

A. Before proceeding with installation check internal dimensions of the concrete basin.

If deviations from the correct dimensions and elevations are found these should be discussed with Parkson.

B. Drill and install bottom cone drop in anchors at locations shown on Loading

Diagram, Drawings 150837-01-04/06/07, Rev. 1. Drill 1” dia. hole 4” deep for full embedment. USE SETTING TOOL TO SET ANCHORS. Cut threaded

¾” rod, if required, to achieve maximum of 3” projection above bottom of cone.

Place a nut and leveling washer on each anchor, and adjust to put the top of the washer at the elevation for the bottom of the bottom cone. This elevation is 15’-0” below the final effluent weir elevation for a standard 40” bed unit or 18’-4” for a deep 80” bed depth unit. IT IS IMPORTANT THAT ALL THESE ARE SET TO CORRECT ELEVATION. If the floor is too high, chip out around the anchor to allow the nut and washer to go down to the correct elevation.

2-1

C. One bottom cone with a hatch is provided for each basin to allow access to the area below the cones once they are all in place. If possible it should be placed so that the hatch faces another cone rather than the wall for easy access. The remaining cones have no hatch.

Lower cones onto anchors and brace temporarily. Fit bottom cone washer, Item 210, Drawing 15083701-07, Rev. 1, and anchor in each cone. Do not tighten so that cones can be moved.

D. Each cone-to-cone joint is bolted together, and each cone edge to wall is anchored through the four holes in each cone top edge. Use wood wedges between cones and between cones and walls to get even spacing around the top. The cone-to-cone gap should be approx. 1" at the top and the cone to wall gap should be approx. 1/2" at the top. Tighten the bolts or anchors enough to achieve these spacing. Do not attempt to tighten the bolts or anchors all the way. The cones should be level. When spacing and leveling is correct tighten bolts on braces and on bottom cone anchors. Recheck and adjust as required. Remove wedges.

E.. The internal cone brackets each have a hole, top and bottom, for a bolt to tie them into the concrete that will be poured under the cones. Attach the long bolts, Item 150, with the head end under the cone. A nut is placed on each side of the bracket and cone so that there is minimum projection past the bracket. The head end of the bolt will be secured in the concrete when it is poured.

F. Before pouring concrete remove all trash and water from basin and check bottom cone anchor nuts are tightened.

G. The area under the cones will be completely filled with concrete in three separate pours. Do not fill with one pour as damage to cones may result. The concrete pump hose and vibrators can be pushed through the square opening at the top corners of the cones. The primary requirement for the concrete is that it should flow easily to fill all spaces. The final pour has to fill the gaps between the cones to as close to the top as possible.

The following concrete mix can be used under the bottom cones:

• 8.125 Cu. Yd. per cone

• 2000 psi @ 28 days

• Cement 420#

• Fly Ash 180#

• Fine Agg. 1850#

• 3/8” Max Agg. 1000#

• Water 36 US Gallons

• Water Reducer 24 Fl. Oz.

• Superplasticizer 64 Fl. Oz.

2-2

H. Close the access hatch with the slips provided. Make first pour to minimum depth of 18". Remove any concrete that drops inside bottom cones before it hardens.

Allow to cure. Use duct tape to seal around hatch to prevent leakage of concrete into cones.

I. The second pour should fill to half way to the top of the cones. Remove any concrete that drops inside bottom cones before it hardens. Allow to cure.

J. The third pour should fill the gaps between the cones to as close to the tops as possible. Any gaps remaining will have to be filled afterward with grout or caulk.

Remove any concrete that drops inside bottom cones before it hardens. Allow to cure.

K. Use a grout or caulk to fill the remaining gaps between cones and between cones and walls. All joints must be filled to the top.

2. INSTALLATION OF FEED ASSEMBLY, FEED MANIFOLD AND SUPPORT CHANNELS

Once the feed assemblies are in place it is impossible to reach the bottom of the bottom cones. All trash should be removed before feed assembly installation and care taken to prevent trash from building up in the cones. Everything dropped into the cone will have to be removed eventually by reaching down with a hook on the end of a stick and pulling it out.

A. Before setting feed assemblies in place the leveling screws in the internal brackets in the bottom cones on which they will rest must be adjusted. All these screws must be at the same elevation with respect to the effluent weir. At this point, do not set locking nuts.

If you have a deep bed filter (effluent weir 18.33 feet above the bottom of the bottom cones) then the tops of these screws should all be 14.12 feet below the weir elevation.

If you have a standard bed filter (effluent weir 15.00 feet above the bottom of the bottom cones) then the tops of the screws should all be 10.79 feet below the weir elevation.

B. Anchor the support angles, Item 310, in the positions shown on Drawing

15083701-01, Rev. 1 & 15083701-07 Rev.1 Strike line along the wall 9 1/2" below the top of the wall. (Assuming 8" reject support frames and 1-1/2" grating.) The top of the support angles should be aligned with this line.

2-3

C. Position the 8" rubber boots, Item 460, over the feed connections on the feed assemblies, Item 290. Slide them well down out of the way so that they will not interfere with positioning the feed manifold.

D. Lower the feed assemblies into place making sure that the feed connection points in the right direction to connect to the main feed manifold. Check that the feed assembly is vertical. THE TOP END OF

THE FEED ASSEMBLY MUST BE IN THE RIGHT POSITION. CHECK

THAT THE TOP OF THE ASSEMBLY IS DIRECTLY ABOVE THE

POSITIONS SHOWN IN THE LOADING DIAGRAM, DRAWINGS

15083701-04, Rev. 1. With a wrench, adjust each leveling screw so that all four are making solid contact with each cone bottom, then tighten the locking nuts to maintain the leveling screw settings. It is extremely important that each feed assembly is vertical and solid contact is made with all four leveling screws. IF THE TOP OF THE FEED ASSEMBLY IS

NOT IN THE CORRECT POSITION MANY PROBLEMS WILL BE

EXPERIENCED LATER ON.

E. Place the long lengths of the reject manifold pipe down in the basin at this time. It may be difficult to do so at a later stage.

F. The feed manifold is suspended in the basin by pipe clamps, which hang from the reject support frames and grating supports. Note that some of the frames and supports may be different with holes for handrail mounting, hangers or other requirements. Determine which supports go where from the drawings. Mount frames and supports and assemble the feed manifold supported by the clamps so the pipe cannot move up or down. Connect the feed manifold to the feed assemblies with the rubber boots.

3. INSTALLATION OF REMAINDER OF FILTER COMPONENTS

A. Bolt the sand washer reject troughs Item 390, Drawing 15083701-02/03, Rev. 1, to the underside of the reject frames over each feed assembly orienting the reject pipe as shown. The top of the feed assembly should be centralized in the hole at the bottom of the reject trough. If it is not centralized make adjustments with the position of the trough on the frame and the position of the frame on the support angles. If sufficient adjustment cannot be made then the leveling screws, which the feed assembly sits on will have to be adjusted so that the top of the feed assembly moves to the required position.

B. Refer to Drawings 1012217-01, Rev. 0 and 1012218-01 Rev.0, for assembly of the remainder of the sand washer. Slide the airlift pumps down into the feed assemblies making sure the head of the airlift is properly seated. If all elevations are correct the distance from the top of the airlift pipe to the top of the reject trough should be close to 11-3/4". Call Parkson if it varies more than 1" from this.

2-4

C. Now assemble the sand washer. Position the lower guide collar, Drawing 1012217-01, Rev. 0 and 1012218-01 Rev.0, as shown. Bolt the inner wash ring halves, Item 100, together with the nylon hardware. DO NOT OVERTIGHTEN NYLON HARDWARE. Do not try to bolt the two halves tight together or plastic ring moldings may break. The outer wash ring halves are assembled with one neoprene gasket around the top and a second pair of gaskets between the two halves. The two halves bolt together with nylon hardware and then the assembly is bolted up to the bottom of the reject trough with stainless hardware. Bolt the two halves together first. Then bolt the assembly up to the bottom of the reject trough.

All gaskets must be in place. Slide the upper guide collar into place and secure.

Now back out the bolts on both the guide collars to centralize the wash rings around the feed assemblies. Locate the splash hood clamp on the splash hood so that the splash hood sits in the position shown.

D. Assemble the PVC reject manifold. This connects to the reject troughs with rubber boots and is supported by pipe hangers.

E. Mount the instrument panel to its support bracket on the feed channel wall as shown. Inside the panel are the required fittings to connect the airlifts to the panel.

F. Mount the level switch, Item 670, to the reject frame just below the panel so that the float is at the same approximate elevation as the main effluent weir. Make electrical connection to panel as shown.

4. SAND LOADING

A. Refer to O & M manual section on sand loading.

B. Sand should not be loaded until all work above the filter has been completed and shortly before start up. It is absolutely essential to filter operation that no foreign objects are dropped into the sand. This is impossible to avoid if work continues above it.

C. Remove every other grating panel to allow sand to be delivered to all areas of the basin.

D. Before sand loading ALL TRASH MUST BE REMOVED FROM THE BOTTOM

OF THE FILTER. SAND IN FILTER MUST BE KEPT FREE OF FOREIGN

OBJECTS.

2-5

E. When filter is clean fill with water to within one foot of effluent weir level. This will help distribute the sand and protect the components from sand blasting. FILL

BASIN VIA THE FEED MANIFOLD. IF THIS IS NOT POSSIBLE AND BASIN

MUST BE FILLED BY ANY OTHER MEANS THE FEED VALVE AT THE END

OF THE MANIFOLD MUST BE OPEN TO ALLOW AIR TO ESCAPE.

F. Sand will be blown into filter from pneumatic trucks. DIRECT THE SAND INTO

THE WATER. DO NOT SAND BLAST INTERNAL COMPONENTS OR WALLS.

Distribute the sand evenly within each basin ensuring that the total sand amount to be delivered is divided evenly among the basins. When level the sand should be at the level shown on the drawing. Typically the amount of sand delivered will be a little more than is required to reach this level. A few inches of extra sand is not a problem. Drain water to below the sand to level it out.

G. ANY OBJECT DROPPED ONTO SAND BED AT ANY TIME MUST BE

REMOVED IMMEDIATELY. IF NECESSARY DRAIN WATER TO FIND OBJECT.

IF AIRLIFTS ARE OPERATING STOP AIRFLOW IMMEDIATELY AND

RETRIEVE OBJECT.

H. NEVER ALLOW WATER TO FLOW BACKWARDS THROUGH FILTER. This could occur if a filter feed valve is closed with the filter full of water and the feed channel is allowed to drain down. Opening the feed valve to the full filter would allow the water to drain out through the feed pipe. This can cause sand backflow to occur which would plug the feed assembly.

NOTE: WE DO NOT ACCEPT LIABILITY FOR ANY CORRECTIVE OR OTHER

3.1 Function of The DynaSand® Filter

The Parkson DynaSand® Filter provides a unique filtration system since it continuously cleans the sand bed while filtering liquid suspensions to the designed effluent quality.

Feed water is passed upwards through the sand bed, exiting from the top of the filter as clean water. At the same time, sand is continuously removed from the bottom, cleaned, and returned to the top. A small portion of the filtered water is used to wash the sand and leaves the filter as a reject stream.

The feed is introduced into the filter through the FEED PIPE. See Figures 1 and 2. The feed then passes down through the FEED PIPE to the DISTRIBUTION RADIALS where it is introduced into the sand bed. The distribution radials serve to distribute the feed water flow evenly across the sand bed. From there, feed water passes upwards through the sand bed, being cleaned in the process. The clean water (FILTRATE) passes over the FILTRATE WEIR at the top and leaves the unit.

Dirty sand is continuously removed from the bottom of the unit by the AIRLIFT PUMP and is lifted to the CENTRAL REJECT COMPARTMENT at the top of the unit. The airlift pump has air injected into the bottom causing dirty sand and water to rise up it. This process also creates a powerful air scour of the sand, which helps to separate solids from the sand.

From the central reject compartment, the dirty sand falls back to the top of the sand bed through the SAND WASHER. The sand washer is a section of pipe, which is connected at the top end to the reject compartment and is open at the bottom to the top of the sand bed. At the same time, a portion of the filtrate is passing upwards through the washer and this counter flow washes all the dirt from the sand. As a result, the sand that falls out of the washer onto the top of the sand bed is now clean. The wash water carries the dirt out of the top of the sand washer into the central reject compartment. From there it flows over the reject weir and out of the unit as REJECT WATER. The amount of reject water flow is controlled by the height of the REJECT WEIR in the central compartment relative to the level of water in the filter tank.

3.2 Inspection, Installation and Assembly of the Filter

Prior to installation of the filter please refer to the following items in addition to this section:

Drawings included at the back of this manual.

A Components Check Out Before installing the filter internal components they should be thoroughly checked for damage and missing items. Please refer to the general arrangement drawing and the packing lists.

B Splash Hood

The splash hood, which is shipped loose, is a short length of white PVC pipe with four (4) brackets. See Figure 3. Threaded rods from the reject trough assembly pass through the holes in the brackets. The long bolts that hold two

(2) of the brackets to the splash hood rest on top of the airlift splash plate.

Wing nuts secure the splash hood to the threaded rods.

The splash hood directs sand and water from the airlift into the reject compartment. If it is not correctly placed, sand loss and poor performance will result.

C Air Control Panel

One or more compressed air control panels are provided for the filter. See drawing entitled “Instrument Panel” and “Including the Top-Feed DynaSand® Filter in Your System” in section 3, for details. The control panels are mounted at the top of the filter. Air hoses connect them to the top of the airlift air supply tubes, which protrude from the top of each airlift assembly. Attach the air hose to a 1/4” flexible tubing as shown in Control Panel drawing.

The air control panel allows control of the rate at which air is feed to the airlift.

This is how the rate at which sand is pumped in the filter is controlled. To provide a constant pressure to the flow meter, a pressure regulator is provided which is normally set to 30 psi. A constant pressure and flow rate will be maintained as long as the supply pressure is higher than the setting on the regulator. The panel has a rotameter gauge, which allows control and measurement of the rate of airflow to the unit. Above it is a back pressure gauge that shows the backpressure being produced by the airlines and air chamber on the airlift pump.

3-6

The air panel may also include a solenoid valve to control air flow through the panel. This is controlled either by an interlock with the feed water pump or by a float switch mounted at the top of the unit.

The air panel may also include a second solenoid valve and a timer which are associated with an “air burst” feature. This system provides a timed burst of high pressure air to the airlift whenever it is started up.

This air burst bypasses the control gauges and helps the airlift to start pumping sand.

The air control panel is provided to control the supply of air to the airlift.

See the control panel drawings at the end of this O&M Manual. The panel contains the following items:

a. Air Filter: This provides final filtration and water separation for the air entering the panel. Open the drain at the bottom of the filter if any accumulated water is seen.

b. Regulator: This reduces the supply air pressure down to the pressure required by the system. It should be set to 30 psi.

c. Solenoid Valve #2 with Manual Operator: This is provided for automatic control of the air supply to the airlift. It is controlled by the level switch, which registers the water level at the top of the filter. When water is flowing through the filter, the water level rises to the level of the effluent weir. At this level, the level switch is closed and the solenoid valve is open allowing air to flow to the airlift. When there is no water flowing through the filter, the water level drops to the level of the reject weir. At this level, the level switch is open and the solenoid valve is closed so that no air flows to the airlift. This system is provided so that the airlift will not continue to bring up dirty sand to the top of the filter when there is no water available to wash the sand. The manual operator allows the solenoid valve to be opened in case of electrical failure.

d. Rotameter: This allows selection of the rate of airflow to the airlift. See section 3.4 for settings.

e. Back Pressure Gauge: This shows the backpressure being produced by the airflow through the airlift and associated tubing.

It should normally read below 15 psi. See section 3.7.F.

3-8

f. Solenoid Valve #1: This solenoid valve is associated with an

“Air-Burst” feature, which also includes a timer. The airburst provides a timed burst of high-pressure air to the airlift whenever it is started up. The normal air rate setting, while sufficient to pump sand, is not always high enough to get it started. The burst of air ensures that the airlift starts to pump sand when flow to the filter starts. When the level switch closes, the timer cycle begins and solenoid valve #1 opens. At the end of the timed cycle, the valve closes.

g. Timer: The timer is provided for the airburst solenoid valve described above. It should normally be set to three seconds.

Set the range setting in the little window to 10 seconds. Set the knob on the front to 3.

NOTE: Whenever the air supply line on the airlift is not connected, seal it off with tape to prevent entry of sand or dirt.

D Headloss Gauge

The headloss gauge type depends on the feed arrangements to the filter.

If there is an open top feed channel, the headloss gauge consists of a float and pointer attached to a scale. This gauge mounts to the wall of the feed channel.

If feed water is piped directly to the filter, the headloss gauge is a transparent plastic tube. It has inch markings on the outside and a float ball inside. This gauge is to be connected to the fitting provided in the vertical feed tube just below the top of the tank top.

The headloss gauge shows the water pressure, or head, on the feed side of the filter. It gives a direct reading, in inches, of the loss of head through the sand bed. Headloss is an important measure of filter performance.

E Piping and Valving

Correct piping and valving to the filter are VERY IMPORTANT FOR PROPER OPERATION. Please refer to “Including the DynaSand®Filter in Your System” The most important consideration is prevention of air entering the feed.

3-9

NOTE:ONLY Drain the unit through the provided drain valve. See Section 3.9.A in this manual for the correct draining procedure.

F Sand Addition

IMPORTANT: BEFORE FILLING WITH SAND CHECK THAT THE

FILTERIS COMPLETELY FREE OF FOREIGN OBJECTS. REMOVE

THE INSPECTION PORT PLATE TO CHECK THAT NOTHING HAS

FALLEN INTO THE FILTER. THIS SHOULD THEN BE REPLACED

AS EXPLAINED IN THE INSTALLATION INSTRUCTIONS.

ONCE THE FILTER CONTAINS SAND ANY FOREIGN OBJECT

DROPPED INTO THE FILTER WILL CAUSE BLOCKAGE OF THE

AIRLIFT. PLEASE ENSURE THAT THIS DOES NOT OCCUR.

ANYTHING DROPPED IN MUST IMMEDIATELY BE REMOVED.

STOP THE AIRLIFT (IF RUNNING) AND REMOVE THE OBJECT

FROM THE TOP OF THE SAND BED.

Use the following procedure to add sand:

1. Check that the unit is free of all foreign material.

2. Check all piping connections and ensure that all filter components are in place.

3. Fill the unit with clean water. Fill to three feet below the level of the filtrate weir. This will minimize dust production; protect the internal components and help spread out the sand. Check for leaks.

4. Place a coarse screen over the filter so that no foreign objects can enter with the sand. If sand delivery is by pneumatic truck, a simple cover may be used to control the large amount of dust created.

5. IN COMPLIANCE WITH O.S.H.A. STANDARD 1910.134, A

DUST RESPIRATOR MUST BE WORN BY ALL PERSONNEL

ASSOCIATED WITH SAND LOADING. See the Material Safety Data Sheet included. See page 3-12.

6. Add sand at a slow rate and distribute evenly across the filter.

Adding sand at a high rate and failing to distribute it evenly across the filter can cause shifting of the internal components. Sand in 100-

lb. Bags can be loaded by hand from a fork lift truck. 3000-lb. Jumbo bags will require a crane or hoist. Pneumatic truck delivery requires close enough access for the short delivery hose.

3-10

When filling from a pneumatic truck, a simple cover may be used to control the large amount of dust created or a “dust-arrestor” device which connects to your fresh water supply via garden hose, keep hose end under control. DO NOT SAND BLAST WALLS OR

INTERNAL COMPONENTS.

7. Fill unit with sand until the level is 6’-1” below the top edge of the filtrate weir. This is the large weir at the top of the unit that the clean water flows over before leaving the filter. Use a marked measuring rod to determine the sand level. The sand should be leveled out across the filter to get a reasonably accurate average level. Do not add all the sand supplied since an excess is usually supplied for loss during shipment. Sand left over may be stored in a dry location for possible future use.

8. The sand must be washed before putting the filter into operation.

See section 3.2.I for the sand washing procedure.

9. The sand specified for your filter application is in conformance with Parkson's 0.9 mm filter media specification. The sand weighs approximately 100 lb. Per cu. ft. dry. See section 3.9.D.

G Reject Weirs and Reject Rate

Reject flow rate is one of the most important operating parameters of the filter. Reject water is produced by allowing a small but steady flow of clean filtered water to flow up through the sand washer. As it does so, it washes out the dirt from the sand that is falling down through the washer. The dirty reject water flows out of the top of the sand washer into the central reject compartment, then over the reject weir and out of the filter.

The amount of reject flow is controlled by inserting or extracting loose reject weir plates. These weir plates slide into a slot in the central compartment that has a permanently-glued-in-place 5" weir at the bottom.

Normally, four different reject weir sizes are supplied in a set, one set for each airlift. They are shipped loosely.

If possible, consider a means for occasional measurement of the reject flow. Flow rates are usually small, and bucket and stopwatch methods are adequate. Because of the high solids concentration in the reject, in-line flow meters are liable to foul.

H Sand Washing Procedure

New sand has a certain amount of fine material that must be washed out before the filter is put in operation. Use the following procedure:

1. Check that all removable weir plates are out of the slot in the reject compartment.

2. Start a supply of clean water to the filter. It is essential that enough flow is supplied to provide the reject flow given in Section 3.4.C. Do not provide less than this amount for each filter. It may be possible to use the water, which the filter is intended to treat if the solids concentration is low, but clean potable water is preferable. The water may be supplied by hose to the top of the unit or through the feed piping.

3. Start the air supply to the airlift at the rate given in Section 3.4.B This will start pumping sand to the top of the airlift. If the airlift does not pump sand, see Section 3.7.C. The fine material will be cleaned from the sand by the reject water flow.

4. Sand washing will require at least 6 to 12 hours. Check that sand is being pumped and that water is running over the reject weir during this time. The sand will be clean when the reject water is no longer cloudy.

5. Some of the fine material will settle out in the reject compartment where it will build up. At the end of the sand washing procedure swirl the water around in the reject compartment by hand so that this material is carried out over the reject weir.

3.3 Pre-Startup Check

Before start-up the following components should be checked and tested separately.

The filter cannot be started up nor operated until ALL of the ancillary equipment is fully operational. All pumps handling feed, reject and filtrate flows must be up and running. The air supply must be connected. Any chemical pretreatment equipment should be on-line and a supply of chemicals should be available.

It is not possible to do a meaningful start-up unless the filter is fully configured for normal operation.

3-13 pmurphy Highlight

A. Check all piping and connections. It is a good idea to hydraulically test the system before sand addition.

B. If sand is in place, check that it is at the proper level. Check that the headloss gauge and splash hood are in place.

C. . Do not test-run the feed pump for more than a few minutes if sand is in place.

D. Adjust the regulator on the control panel to 30 psi. Check that air can pass through the system up to the maximum reading of the air flow meter without more than 10 to 15 psi backpressure.

E. Check that chemical-metering pumps are properly connected and are delivering their rated flow to the system. The appropriate chemicals should be available for this test.

F. Check other equipment manufacturers' start-up instructions.

3.4 Start-Up

After the sand has been washed (see Section 3.2.I), use the following procedure for initial start up:

A. Place a two-inch reject weir plate in the reject compartment slot. Start the feed flow at a reduced rate.

B. When the reject weir overflows start the air supply to the airlift pump. If your unit is equipped with a solenoid valve operated by a float switch or pump interlock this should happen automatically. The float switch should be adjusted to switch on when the water level is just below the filtrate weir.

Adjust the airflow to 90 SCFH as a safe starting condition. If the air supply fails, or the airlift pump does not begin pumping sand, stop the feed and see section 3.7.C. Sand should be seen coming out of the top of the airlift or felt by hand at the bottom of the splash hood. If just water, or air and water, comes out of the top of the airlift pump then sand is not being pumped.

C. Insert or remove reject weir plates to produce a reject flow of approximately 7-14 GPM. Flow can be found by measuring water depth over the reject weirs.

See the table at the end of this section. Note that if sand is not being pumped the reject flow rate will be much higher for any given weir height. This is because the reject flow is slowed down by the sand as it falls down through the sand washer. Any time the air rate is adjusted, the reject flow should be checked. It may be necessary to change the reject weir height.

3-14

D. Check the headloss gauge reading. It should be in the neighborhood of 6-26 inches at the design flow of 2750 GPM. The headloss is a measure of the feed pressure required to drive water through the sand bed. For a fixed flow rate it will vary according to how dirty the sand is. If the headloss reading is seen to be climbing out of the normal range then the sand must be cleaned at a higher rate by increasing the air rate.

E. Gradually increase the feed flow to the rated value for the filter. Check that the headloss reading is stable and is at or below the value given above.

F. After the operator is familiar with the installation and the upstream plant conditions are stable, then the sand (air) rate and the reject rate may be reduced for more efficient operation. For stable operation do not decrease the air rate below 70 SCFH and the reject rate below 7 GPM per filter.
