Media Installation Instructions [Type here] Page | 1

AquaFloc Filters Media Installation Instructions

General Media Installation Information:

Do not let the bags of media be exposed to direct sunlight, as the bags will rot. Outside storage is generally acceptable. Try not to let the media get frozen by storing it outside.

If it does become frozen, it will not become damaged, but it MUST be thawed before it is installed.

Backwash water must be available to clean the media once you complete the installation of the silica sand layer. Installation of all of the gravel layers and the air wash grid can be completed before any backwash water is available. Installation of the sand and anthracite cannot be completed without full backwash flow.

To complete the installation of the media the following water will be required:

1500 gpm Max for 10 - 12 minutes up to 5 backwash cycles for each of the four filters.

360,000 Gallons Maximum Total

To avoid bed upset maximum backwash rate without air scour is 15 gpm/ft2 or 1500 gpm.

All layers except the gravel will need to be skimmed to remove the very fine material.

Operators can choose to backwash at faster rates and longer times as opposed to doing multiple skimmings, but every layer (except gravel) must be skimmed at least once.

There are many ways to get media into the filter safely and effectively. It can be lowered in bags, dropped down a chute, dropped down a pipe, etc. One method that has worked effectively on large filters is to attach a length of hose to the bottom of a drum or basin.

The media is then dumped in the basin and is spread by a person in the filter holding the hose. Otherwise the person in the filter must spread the media with a shovel or rake.

With this technique, the hose must be at least 2-1/2” (fire hose) or larger.

To control dust when placing media in the filter, it is effective to place a garden hose in the chute or pipe that the media pours down. Filter masks must be used to avoid exposure to the silica fines from the sand and gravel.

Normally more media is shipped than is required for the layer depth required. Add only the media required for the proper layer depth of the gravel regardless of quantity shipped. Load all of the sand.

Media Installation Instructions [Type here] Page | 2

Filter Preparation:

1. With the filter empty, mark the media layers on the wall of the filter in a visible location.

Put Marks at 10-3/4”, 17-3/4” 21-3/4”, 25-3/4”, 29-3/4” from the bottom.

Record the depth of the media (measurement from the top of the filter) for each layer after it has been installed.

2. Check that the filter floor and the laterals are all level. If the floor is not level, level the header and laterals, do not make them parallel to the floor.

3. Install the PVC laterals by screwing the male threaded end into the integral underdrain ports. Hand tighten only. Install with drilled orifices facing the bottom.

Support the end of the lateral at all times. Be careful to avoid cross threading. Use Teflon tape or paste on the threads of the laterals.

Gravel Installation:

All gravel layers can be installed dry.

Procedure

1. After the filter has been prepped, the first layer to be added is the gravel, 1-1/2” x

3/4”. Be very careful not to slip and fall on the underdrain laterals. When slightly less than the calculated amount of gravel has been added, grade the gravel gently to the level of the markings on the wall, adding more media if necessary. Stand on the plywood to avoid upsetting the graded sections.

2. Repeat step one for the 3/4” x 3/8” layer, 3/8” x 3/16” layer, and the 3/16” x 3/32” layer. This is not going to be a quick process, but it is important that the layers be flat and segregated.

Air Wash Installation:

The airwash must be placed after the 3/16” x 3/32” gravel has been installed and before the 2-3 mm gravel.

Procedure

3. Place the header and the support pipes first, securing them into position. Make sure that the header is securely tightened to the filter wall. If air leaks at this point, the airwash will not work and the leak may upset the filter bed.

4. Once the header and supports are in place, thread in the laterals. Make sure that the slots/holes in the lateral pipe are pointing downwards.

Media Installation Instructions [Type here] Page | 3

Final Gravel Installation:

Procedure

5. Install the 2-3 mm Gravel after the Air Wash Grid has been installed.

If you use a garden hose to control dust, make sure that it is not allowed to run or drip directly onto the media. Even a dripping hose can create a divot in the fine media. Use a spray nozzle instead of open hose.

Workers may not walk directly on the media any more. After the 2-3 mm gravel has been installed pieces of plywood 2’ - 3’ square must be used to evenly distribute the weight of the workers.

After all of the silica gravel is placed the next layer to be added will be the filter sand.

This will be placed in the same manner as the gravel.

Sand Installation:

6. Now the layer of .45-.55 mm sand is ready to be added. This layer is 12” thick. The media must be poured as gently as possible onto the 2-3 mm gravel. Add 1/4 of the sand that has been shipped to each filter. Spread the fine sand equally and level it with a 2x4.

At this point, water will be required to backwash the silica sand.

Backwash/Initial Bed Cleaning

7. Fill the filter at 500 gpm until the water is above the backwash troughs. NEVER BACKWASH AT 15 gpm/ft2 UNLESS THE SAND IS IN AND THE WATER IS POURING

OVER THE BACKWASH TROUGH.

8. Once water starts pouring over the backwash troughs, increase the backwash rate to 15 gpm/ft2 or 1500 gpm. Hold that rate for 10 - 12 minutes. Drain the filter to about 18” below the top of the sand.

9. There should be a layer of fines on the top of the sand. Remove the top ¼” of the sand by undercutting with a flat trowel or shovel and discard. Do not rake the material, as this will cause the fines to be pushed into the filter bed.

10. Repeat steps 7 through 9.

This should remove the extra 1/2” of media that was added in step 3.

At this point all fines should be removed. If they are not, filter runs will be shortened, and backwashing will be needed more frequently than it would be in a fully cleaned bed.

It may be necessary to backwash a third or even up to five times as determined by Filter Tech Systems’ Technical Representative.
