3.0 System Description
This section explains how water moves through the system. This system is a collection of components working together. If one component fails, it may shut down other components or the entire system. Understanding the overall system helps troubleshoot.
3.1 Theory of Operations
The drawings in Appendix A show tag identifiers.
a. System components upstream of the ProAct system are (in order of primary treatment water flow):
i. An influent weir tank; and
ii. Two influent frac tanks.
b. The ProAct system water-bearing components are (in order of primary treatment water flow):
i. A transfer pump (TP1), draws water from the influent frac tanks;
ii. A 2-18 sand filter (Pods 1 and 2), which removes particulates;
iii. Two 2-stage bag filters in series, which remove smaller particulates;
iv. An anti-scalant injection system; and
v. A reverse osmosis system, from which treated water (permeate effluent) flows; and
vi. A discharge line with flow meter, pressure transmitter, and sample port which marks the end of the ProAct system.
c. Secondary flows include:
i. A sand filter bypass line;
ii. A sand filter backwash line; and
iii. A concentrate effluent line, leaving the RO system.
iv. The sand filter backwash line and concentrate effluent line run into the influent weir tank.
In addition, many valves, gauges, and transmitters control flow and allow the operator to monitor system operations. Water leaving the ProAct system flows into the three effluent frac tanks (by others).
d. ProAct non-water-bearing components are:
i. A control panel with a programmable logic controller (PLC);
ii. An air compressor for operating the sand filter backwash valves and for blowing down the bag filters; and
iii. Trailer accessories, such as heater, fan and lights.

4.2 Allen Bradley CompactLogix & Red Lion Touchscreen
The PLC actively monitors and controls the treatment system. The PLC controls system operations in proper response to system conditions. The PLC gets inputs from transmitters and switches, then signals the pump to start or stop and valves to open or close.
The PLC also safeguards the system. Automatic shutdowns programmed into the PLC protect operation. During fault conditions, the PLC trips an alarm and shuts down malfunctioning component(s) or, if needed, the entire treatment system.
The operator communicates with the PLC through human-machine interface (HMI) screens, which are described in the following pages.
All screens have a MENU button in the lower left corner. Press this button to return to the Main Menu screen. An alarm banner at the bottom of each screen cycles through active warnings and alarms. Blue arrows on many screens let the user go to the upstream or downstream screen.

5.3 Electrical Connections
This system needs an external power source; it has no generator. The electrical system is currently configured for a specific configuration. The box below gives details on the system’s current electrical configuration.
The electrical system for this unit is configured for a specific power supply. Failure to connect the correct power to the remediation system will result in substantial damage.
ProAct Services recommends using a professional electrical contractor or a certified ProAct technician to connect the main power supply to this remediation system.
Never power up the system unless absolutely certain the correct power supply is connected.
Severe damage to the electrical components is likely if the wrong power supply is connected and the system is powered up.
The correct power supply for this system is as follows:
Power Supply 480-3-60, 3-wire Service: 200 A Maximum Fuse: 125 A
FLA: 92 A
Follow these steps to connect the system to a power source:
a. Turn OFF the unit main power disconnect switch.
b. Shut OFF all circuit breakers in the control panel and in the single-phase breaker box to the left of the control panel.
c. Connect the correct electrical power to the trailer main disconnect.
d. Have a qualified person use a multimeter and verify the voltage is correct. It can often be useful to record these voltages.
e. Turn ON the main power disconnect switch.
f. Turn ON the Main Control Panel breaker that supplies power to the transformer.
g. Bump test TP1 (3 phase) to ensure proper motor rotation.
i. Have a qualified person open the Main Control Panel. Exercise caution -the panel is live.
The panel is live. Touching components or wires could result in electrical shock, burns or electrocution.
ii. Briefly switch TP1 to HAND using the control panel mode select screen.
iii. Have an assistant verify that the motor rotates in the proper direction shown by the arrow on the pump housing.
iv. If rotation is correct, go to Step l, otherwise go to Step h.
h. Turn OFF the Main Control Panel breaker that supplies power to the transformer.
i. Turn OFF the main power disconnect switch.
j. Have an electrician swap and 2 of the 3 main power (hot) lines.
k. Go to Step e.
l. The system is properly connected to the main power supply.
5.4 Startup Sequence
Follow these steps to turn on the WTS electrical components. If an alarm is triggered, a component fails to operate, a leak is detected, or any other malfunction is observed, stop the WTS, troubleshoot the problem and resolve before continuing.
1. Set the Reverse Osmosis unit (RO) controller to desired operation BEFORE starting the entire system. (Please see OEM Operation and Maintenance Manual for specific startup criteria of the RO unit).
2. Ensure all filters have elements/socks.
3. Set valves to recirculation configuration to prevent discharge until WTS is checked.
4. Follow Steps a–g for each of the system units. Start at the beginning of the treatment train and move downstream.
a. If the unit has a power switch, turn it to “ON”
b. If there is a 3-way or 2-way switch, turn the component to “ON” or
“HAND.”
c. If the associated component starts running, go to step d, otherwise, troubleshoot.
d. Prime pump, if needed.
e. Check all plumbing connections and resolve/repair any leaks.
f. Turn switch to “OFF.”
g. Repeat leak test for all components in the treatment train.
5. After verifying that all components work, and there are no leaks, turn all 3-way switches to “A” or “H,” and turn all 2-way switches to “OFF” or “ON.”
6. Continue to recirculate, or set valves to discharge into the effluent tanks, as desired.
7. Record all gauge readings.
5.5 Cold Weather Operation
Water can accumulate in the filters/membranes, filter media, pumps and plumbing. If the water in these components freezes, system damage is likely. Do not allow the machine to freeze unless it has been totally drained for at least 8 hours. The system must also thaw a minimum of 24 hours before starting.
This system has components that are sensitive to antifreeze, winterization of the system will require draining all equipment and plumbing completely without the use of antifreeze for storage.
When operating the system in outside air temperatures less than 32°F, protect the system from freezing. Failure to do so will cause equipment damage.
5.6 Normal Shut-down
The system may require shut down (deactivation) for repairs, maintenance, or general servicing. ProAct Services recommends these steps:
1. Before deactivating the system, record all flow rates, pressures, and other system or site conditions if needed.
2. On the control panel mode screen turn all components OFF.
3. Turn OFF all disconnects and breakers in the Control Panel and in Breaker Panel.

Table 6.2.4 Troubleshooting Reverse Osmosis System Problem Possible Cause Corrective Action
Low operating pressure
Insufficient feed water pressure or flow Open the feed pressure, open the feed water valve, check for restrictions.
Clogged pre-filter cartridge Replace the pre-filter cartridge.
High flow rates Close the concentrate valve, check the permeate and concentrate flow rates and adjust if necessary. Excessive permeate flow may indicate a damaged O-ring.
Dirty or fouled membrane elements Flush and clean the membrane elements.
Solenoid valve not opening Clean or replace the solenoid valve.
Pump rotating backwards (three-phase power only) Switch any two of the three-phase leads to the motor starter.
Insufficient electrical power Check the fuses or circuit breaker, measure the voltage.
Pump not operating correctly See the pump instructions.
Low permeate flow rate
Low operating pressure See the possible causes for low pressure.
Dirty or fouled membrane elements Flush and clean the membrane elements.
Operating on cold water less than 55ºF (13ºC)
Install a hot/cold feed water tempering valve if more permeate flow is needed. Operate with a feed water temperature of 72º - 77ºF (22º - 25ºC).
Membrane elements installed backwards or damaged concentrate seal
Install membrane elements in the direction of fluid flow. Flush and clean the machine immediately. Membrane elements with damaged concentrate seals should be cleaned and may be returned for repair.
Flow meter inaccurate Check the flow rate manually with a stopwatch and calibrated container.
Low concentrate flow rate, normal or higher than normal pressure
Concentrate valve plugged Remove the concentrate valve stem and/or disassemble the plumbing.
Clean the valve.
Concentrate outlet line restricted Examine the concentrate line for obstructions or kinks, repair or replace the tubing.
Flow meter inaccurate Check the flow rate manually with a calibrated container.
Pressure does not drop when concentrate valve opened
Dirty concentrate valve Disassemble and clean the plumbing to the valve.
High operating pressure
Recycle or concentrate valve plugged
Disassemble the plumbing to the recycle valve and remove foreign particles. Check the concentrate valve stem.
Inaccurate pressure gauge Replace or calibrate the gauge as required.
Restricted or reduced permeate flow rate See possible causes for low permeate rate.
Excessive pressure drop [over 50 psig (3.4 barg)] (high primary pressure -low final pressure)
Restricted flow after pump outlet Check for blockage of the concentrate flow at the inlets and outlets of membrane element housings.
Telescoped membrane element covering membrane element housing outlet port
Ensure that the anti-telescoping (ATD) is located properly on the membrane element.
Severely fouled or dirty membrane elements Flush the machine, then clean it with detergent.
Water flowing when machine is turned OFF
Inlet solenoid valve not closing or seating properly
Clean or replace the valve. Clean the membrane elements with detergent immediately. Water must not pass through the inlet when the machine is
OFF.
Declining rejection (high permeate conductivity)
Dirty or fouled membrane elements Flush and clean the membrane elements.
O-ring seal broken or damaged Replace the O-ring, check the sealing surfaces on the O-ring groove, interconnectors, and end caps. Replace damaged parts.
Change in incoming water quality Open the concentrate valve and flush. Test the water for pH, hardness, TDS, and iron content. A water analysis should be sent to GE Osmonics.
Inaccurate conductivity monitor or fouled probe
Calibrate the monitor with a solution of known conductivity or check the readings with another conductivity meter. Replace or clean the probe.
Check the connections between the probe and monitor.
Switch ON, unit not operating
Pressurized storage switch or float switch has cut power to machine Check the permeate back pressure or position of float in the storage tank.
Thermal overload in motor has tripped
Allow the machine to cool; check the feed water supply and/or AMP draw to the motor.
