3.4 Testing and Compliance

3.4.1 The Government shall be responsible for the ongoing routine water sampling of the system in accordance with ANSI/AAMI ST108 requirements.

3.4.2 The results of the Government’s water sampling shall be provided to the vendor for incorporation into their system O&M management plan.

3.4.3 Upon notification from designated Government representative (LCO, COR, or appropriate designee) that the test results indicate non-compliance with ST108 requirements, the vendor shall:

3.4.3.1 Respond within 6 HOURS by acknowledging receipt and communicating plans to investigate the issue to the appropriate VA POC.

3.4.3.2 Respond to the site, diagnose and identify the root cause of the non-compliance and provide written documentation to the Government within 36 HOURS.

3.4.3.3 Implement corrective actions necessary to restore compliance with ANSI/AAMI ST108 standards within 72 HOURS.

3.5 Sanitization

3.5.1 The Vendor shall perform sanitization of each SPS RO/DI system at least twice annually, and no less than as prescribed in accordance with the manufacturer’s recommended procedures.

3.5.2 Additional sanitization events may be requested by the VA at any time. Upon such request, the Vendor shall respond within 24 HOURS.

3.5.3 Two (2) routine annual sanitizations shall be included in the fixed annual O&M cost.

3.5.4 Sanitization performed in response to non-compliant water quality results will be reimbursed separately, subject to prior VA approval and submission of cost documentation. It is the intent of this SOW that the Vendor’s program will maintain the system in a configuration that ensures additional sanitization is not needed due to non-compliance, so approval of these additional costs will depend largely on demonstration by the Vendor that the non-compliance was due to external factors beyond this scope and not within their ability to foresee and correct.

3.5.5 Each sanitization shall be considered complete only after Government’s water sampling results demon-strate water levels within ANSI/AAMI ST108 limits identified in Table 3. Upon sanitization, the vendor is responsible for any additional sanitization steps if follow-up water sampling results are not in compli-ance with ANSI/AAMI ST108 standards.

3.5.6 The VA may request an additional sanitization which would be funded by the repair CLIN associated with this contract with pricing provided in the contract proposal.

NOTE 2: The pH range for steam is wider than for Critical Water as some steam may not be generated locally but from a centralized/facility system. The need to add chemicals to the boiler and the steam to travel distances over black iron piping may result in higher pH requirements.. A pH of 7.5 in these systems should be avoided.

*NOTE 1 The recommendations for frequency of testing in this table are the recommended minimum frequency. If problems or issues arise with the water quality, it may be necessary to increase the frequency until they are resolved.

**NOTE 2 When using these tests, the user should carefully follow the manufacturer’s written IFU for accurate results.

When measuring Critical Water levels, the water sample must be filled to the brim for these test kits, sealed and, if the sample is held, allowed to cool to room temperature before testing. Testing within 15 minutes of sample collection prevents carbon dioxide absorption that can result in an inaccurate pH.

A.4 Deficiency and Corrective Action

A.4.1 Deficiencies will be documented by the COR. The Contractor may be required to submit a corrective action plan. Continued deficiencies may be escalated to the CO.

A.5 Performance Documentation

A.5.1 The COR will maintain documentation of inspections, communications, deficiencies, and corrective actions in the official contract file.

Point of Use UV Disinfection

• The controller on the left will cycle through part numbers, transmittance, and days until UV Light Bulb replacement.

• To change the bulb, unplug the unit, unscrew the ground wire at the top of the round housing, the push down and turn slightly the large black cap on top to unseat the bulb.

Recirculation Flow

• This recirculation flow is required to meet the water Quality Regulations.

• It is currently set at about 2 gpm. Try to keep it there.

• The flow can be changed by the red handled valve to the right.

Drain from RO, Carbon Tanks, and Hallet UV Purge.

Overflow from RO Storage Tank.

RO Storage Tank Drain.

Drain from Ultrasonic Cleaner.

DI Polishing Tanks.

Water Distribution Pumps

• The pumps will automatically speed up and slow down based on water demand to maintain constant pressure.

• They will cycle between them to even out run time.

On / Off Button

Increase / Decrease Pressure buttons

• Currently set about 50 psi. That should be sufficient.

Operation Indicator:

• Stationary Green = Pressure is at setpoint.

Pumps is OFF and ready to start if pressure drops.

• Rotating Green = Pump running and operating OK.

• Red = Fault. Turn off power and restart.

DI Polishing Tanks.

Tank Vent. When changing the DI Cartridges, isolate the Tanks, open the Drain Valve, press the vents to relieve pressure and drain the water.

High efficiency UV Disinfection

The Units will run Automatically as long as they are turned on.

Isolation valves if you choose to run only one at a time.

Main Disconnect for RO System

Distribution Pumps Control Panel

RO Control Panel.

All that can be done is basically ON and OFF.

System Control Valves.

RO System Pressures

RO System Flow Meters

RO System Inlet Pressure.

This meter is to read 30 PSI atleast while the system is running.

Currently, the incoming water pressure is too low and the Pressure Switch has been bypassed to allow the system to run.

RO System Internal Pressure. It must not be above 200 psi. It can be adjusted by the amount of WASTE is produce. More waste means lower pressure.

Keep the pressure around 150.

The pressure can be adjusted with the Waste Control Valve.

Opening the Recirculation Valve can “help” with the Low Inlet Pressure.Inlet pressure while running is

WAY TOO LOW.

Good system pressure.

Adjusting the Waste Control Valve can change the System Operating Pressure to maintain about 150 PSI.

This is the Waste Flow Rate reading about 1.6 gpm. This seems to be a good setpoint as the System Pressure is about 150 psi.

The Recirculation Rate is about

2.1 gpm. This seems to be good as it is allowing the Inlet Pressure to be above 0 psi.

This is the production flow rate of about 10.8 gpm.

These are “sediment filters”.

They remove small pieces of dirt, rust, and other small particles. These are the first step in the treatment process.

This is the wrench is used to remove the gray housings to change the cartridges inside.

NOTE: All pressure must be removed from these filters or you will not be able to turn the housings.

Isolation Valves to the RO System.

RO System Sediment Filter

NOTE: All pressure must be removed from these filters or you will not be able to turn the housings.

Self Backwashing Carbon Filters.

The display cycles between time of day and days remaining until backwashing.

They are wired such that they both cannot be backwashing at the same time. This allows for a continuous supply of water to the RO System.

This is the MAIN ISOLATION VALVE for the entire system.

This should be shut during any maintenance actions with the exception of filling the Anti-Scalant Tank.

Anti-Scalant Tank.

This tank must not be run dry!

It is to prevent inorganic chemicals like calcium, iron, magnesium from permanently fouling the RO Membranes.

When the tank is about empty…likely after about 2 – 3 weeks, pour a full bottle of the HyperGuard in and fill with the RO Water.

Fill Valve for Anti-Scalant.

Open the black cover on the Anti-Scalant Tank and put the nozzle into it and open the valve.

Influent Flow Meter showing how much water is flowing to the system.

Main Influent UV Light Disinfection.

This is the one that Aleres Engineering Firm requested.

These are the Water Quality Monitors.

These are “extra” in addition to the Contract.

They show the water quality as it goes through the entire system.

The first one on the left is what is coming into the system from the VA water supply. It is reading 59.8 ppm (parts per million) of TDS (total dissolved solids).

The middle on is what is coming out of the RO System.

The one on the right is what is being recirculated and what is actually being used.

GREAT WATER QUALITY. Far better than what is requested in the Contract.

When this meter starts to climb up to around 7, it is best to change out the DI Canisters.

The specification is 14 PPM for SPS Decon Water.

Be sure to check the entire RO system for any shipping damage or parts loss. Also note damage to the shipping cartons. Contact US Water Systems at 1-800-608-8792 to report any shipping damage within 24 hours of delivery. Claims made after 24 hours may not be honored.

Safety Guide

• Check and comply with your provincial / state and local codes. You must follow these guidelines

• Use care when handling the RO system.

• The RO System works on 220 volt - 60

Hz 1PH electrical power only.

• DO NOT exceed 150 psi on the pump or membrane pressure gauge. Damage or injury could occur as a result of exces-sive pressure.

Proper Installation

This RO system must be properly installed and located in accordance with the Installation Instructions before it is used or the warranty will be void.

• Do not install or store where it will be exposed to temperatures below freezing or exposed to any type of weather. Water freezing in the system will break it. Do not attempt to treat water over 100°F.

• Do not install in direct sunlight. Excessive sun or heat may cause distortion or other damage to non-metallic parts.

• Properly ground to conform with all governing codes and ordinances. Use only lead-free solder and flux for all sweat-solder connections, as required by state federal codes.

• Maximum allowable inlet water pressure is 125 psi. If daytime pressure is over 80 psi, night time pressure may exceed the maximum. Use a pressure reducing valve (PRV) to reduce the pressure.

• RO membranes will degrade in the presence of chlorine or chloramines. In these condi-tions, it is wise to consider purchasing a carbon filter system with a chlorine reducing media. Contact US Water Systems for chlorine and chloramine removal equipment.

Rejection, Recovery & Flow Rates

The US Water Systems Defender reverse osmosis system is designed to produce per-meate water at the capacities indicated by the suffix in the systems name under the conditions listed above. For example, the DFROM-4000 produces 4000 gallons per day of permeate water at the listed operating test conditions.

The amount of total dissolved solids (TDS) rejected by the membrane is expressed as a percentage. For example, a 98.5% rejection rate means that 98.5% of total dissolved solids do not pass through the membrane. To calculate the % rejection, use the following formula:

• % Rejection = [(Feed TDS - Product TDS) / Feed TDS] x 100

• Example: 98.5% = [(550 - 8.25) / 550] x 100

NOTE: ALL TDS FIGURES MUST BE EXPRESSED IN THE SAME UNITS, TYPICALLY

PARTS PER MILLION (PPM) OR MILLIGRAMS PER LITER (MG/L).

The Defender reverse osmosis system is designed to reject up to 98.5% NaCl, unless computer projections have been provided or stated otherwise.

The amount of permeate water recovered for use is expressed as a percentage. To calculate % recovery, use the following formula:

• % Recovery = (Product Water Flow Rate / Feed Water Flow Rate) x 100

• Example: 40% = (2.78 / 7.0) x 100

NOTE: ALL FLOW RATES MUST BE EXPRESSED IN THE SAME UNITS, TYPICALLY

GALLONS PER MINUTE (GPM).

System Connections, Requirements and Guidelines

PLUMBING

The membranes and high pressure pumps used on Defender systems require a continu-ous flow of water with a minimum feed pressure of 35 psi, not to exceed 105°F while the system is running.

FEED WATER CONNECTION

1. Locate the 1" FNPT inlet connection on the sediment filter housing.

2. Attach the inlet piping to the 1" FNPT Filter housing inlet.

NOTE: FEED LINE MUST BE MINIMUM 3/4". 12,000 and 16,000 SYSTEMS MUST

BE 1".

Need help? 1.800.390.5936 19 www.uswatersystems.com

PERMEATE (PRODUCT WATER) CONNECTION

1. Locate the 1/2" tubing labeled permeate and attach to the bulkhead in the top of the storage tank. 12,000 and 16,000 GPD systems will have a 1" MPT connection for the permeate line. Ensure that the permeate water can flow freely with no back pressure.

Back pressure can cause irreversible damage to the membrane elements.

NOTE: ALL PERMEATE PLUMBING SHOULD BE DONE WITH PLASTIC OR

STAINLESS STEEL. SOFT METALS WILL LEACH INTO THE WATER STREAM.

CPVC, PVC, PEX AND STAINLESS STEEL ARE THE MOST COMMONLY USED

MATERIAL.

CAUTION: THE PH OF THE REVERSE OSMOSIS PERMEATE WATER WILL TYP-

ICALLY BE 1-2 POINTS LOWER THAN THE FEED WATER PH. A LOW PH CAN

BE VERY AGGRESSIVE TO SOME PLUMBING MATERIALS SUCH AS COPPER

PIPING.

CONCENTRATE (WASTE WATER) CONNECTION

1. Locate the 1/2" tubing labeled concentrate and attach/convey to a drain. Run the con-centrate line to an open drain in a free and unrestricted manner (no back pressure).

It is recommended that an air gap be maintained on the drain line to prevent possible bacterial contamination.

CAUTION: ANY RESTRICTIONS OR BLOCKAGE IN THE DRAIN LINE CAN

CAUSE BACK PRESSURE, WHICH WILL INCREASE THE SYSTEMS OPERAT-

ING PRESSURE. THIS CAN RESULT IN DAMAGE TO THE SYSTEMS MEM-

BRANES AND COMPONENTS.

PERMEATE FLUSH CONNECTION (OPTIONAL)

1. Locate the 1/2" solenoid valve on the system. Connect a pressurized 1/2" pipe to the solenoid valve from permeate supply pump after the storage tank. This will provide clean permeate water to flush the membranes once the RO system has shut down.

Electrical Connections

Main System Power

The main power on the Defender system is available in 220 volt, 60 Hertz, 1 Phase.

Each Defender system is equipped with a 5 foot electrical cord. This can be hardwired in a disconnect box or an outlet box can be installed that matches the cord end for the respective voltage. This should be powered by an isolated 20 amp breaker.

NOTE: If the anti-scalant option was purchased, the injection check valve that comes with the anti-scalant pump should be put in the injection tee on the booster pump inlet plumbing. There is a 1/2" plug that must be removed and the injection check valve can be installed.

BE SURE to Teflon tape the injection check valve threads before installing it in…
