RO System Specifications

Table 1 – RO System Electrical Specifications

Operational Notes

1. All systems rated at 77 Degrees Fahrenheit (25 Degrees Celsius) using 1000 ppm sodium chloride (NaCl) solution. System capacity decreases significantly with decrease in feed water temperature (see temperature correction chart).
2. Chlorine requirements for the feed water are as follows:
   Thin-Film (standard)| 0| ppm
   ---|---|---
   CA (special order only)| 0.1| ppm Minimum
3. Feed water must be filtered to a turbidity of less than 1 NTU.
4. System recovery (permeate to concentrate ratio) must be maintained at the recommended level. A higher than recommended recovery will lead to a premature fouling of the membrane with a loss of permeate flow and permeate quality.
5. Softened water should be used for the feed water to the RO system.

System Installation

Location
Locate R.O. system with adequate clearance from walls and other equipment to enable membrane servicing. Run three polyvinyl tube lines to the system as follows:

• Line #1: Connect raw water feed supply to the solenoid valve inlet in front of the first cartridge filter housing. This will require ½ inch threaded pipe fitting and adaptor for the feed line. If desired, install an isolation valve in this line; ensure the valve opening does not restrict the water flow.

Illustration 3 – Line 1 Connection

CAUTION: Pump and system performance will be adversely affected if the feed/suction line is restricted.

• Line #2: Run a 3/8″ line from the open end of the concentrate valve to a drain. Ensure that no liquids from other lines in the plant flow back through this line.

Illustration 4 – Line 2 & 3 Connections

• Line #3: Run a 3/8″ line from the permeate outlet to desired permeate storage container. Pressurized storage or atmospheric storage tank options are available separately.

Note: The recirc flow line is pre-connected at the factory.

CAUTION: Be sure that all lines are connected before plugging in unit power.

Connection of Multi-Media, Carbon or Softeners to Lock-Out (Shut-down) RO during back-wash or regeneration: If you have pre-treatment equipment and you wish to shut-down the RO system during backwash or regeneration, a microswitch is required (standard with Applied Membranes equipment). Wire the microswitch to terminal labeled Pretreat inside controller. See photo – Page 12.
When equipment goes into backwash or regeneration, the pre-treat limit switch opens and turns power off the inlet solenoid valve, which then turns the RO pump off – and back on when the cycle is complete.

Series 50 Controller

Specifications

Power: 120VAC – 240VAC, 50/60 Hz, +10/-15%, 2.5 watts. Input power is auto selected
Inputs: 3 switch inputs, selectable normally open or normally closed
Outputs: RO pump 1HP (Based on service factor of 1.0 max), Inlet solenoid 5A, 20A maximum total load If you desire to change any switch functions, move that switch to the ON Position.

Note: The switches are factory set to the OFF Position: Auto Reset (disabled), Pressure Fault Retry (disabled), Tank Full restart time delay (2 seconds), Input contact type (NC, open to operate).

Illustration 5 – DIP Switches

CAUTION: The controller is rated for maximum 20A total load. Terminal strip P11 is dry contact for input signals from tank full, pressure fault and pre-treat lockout. Use small gauge 2 conductor cable for these  wire connections.  Illustration 6 – S50 Controller Illustration 7 – Controller Components and Wiring Connections

RO Pump Wiring
The RO pump connects to P4 (L1) and P5 (L2) RO pump terminals. This output can operate 120/240VAC motors up to 1HP directly.
Inlet Wiring
The inlet solenoid valve connects to P6 (L1) and P7 (L2) inlet terminals.
Pressure Fault Switch
The feed pressure switch is connected to the pressure fault input. Low pressure (factory preset 8 psi) will shut system off.
Pretreat Switch
In systems with pretreatment, a pretreat lockout switch can be connected to the pretreat input. This switch should operate when the pretreatment device is out of service.

Note: The output from the pre-treatment device must be a dry contact and must not supply voltage.

Tank Full Switch
In systems with a level or pressure switch, the switch can be connected to the tank full input.

System Operation

Series S50 RO System Controller Operation

General Operation
The unit has a single mode of operation ON with 6 sub-modes or states as indicated by the steady or flashing panel lights. Any light condition other than steady Power ON indicates the unit is effectively in stand-by. If there are no lights – system is OFF and all outputs are turned off. In the operating mode, the unit operates automatically. All inputs are monitored, and the outputs are controlled accordingly. Pressing the Power key will toggle the unit from off to operate or from operate to off. If power is removed from the unit, when power is reapplied, the unit will restart in the mode it was in when power was removed.

Illustration 8 – Controller Sub-Modes

• Power Key: Places the controller in operating mode.
• Pressure Retry: Steady red light.
• Pressure fa u lt: Flashing red light.
• Power On: Steady green light. System operating.
• Pretreat: Flashing green light.
• Tank F u ll: Steady amber light.
• Flush: There is no Flush sequence.

When the power switch is turned ON, the center status LED will light Green, the inlet valve will OPEN and the RO pump will START. (Refer also to Switch – pages 12.)
Under normal operation the RO unit will run until: (A) the storage tank is full (right LED Amber) or (B) Pretreat lockout has occurred (center status LED Flashing Green). When A or B has cleared, after a time delay, the RO unit will restart, and the center status LED will return to Green. Switch setting 3 selects a 2 second- or 15-minute tank full restart time delay.
Upon an alarm signal for Pressure Fault, the left status LED will Flash Red, the RO pump will stop and the inlet valve will close and the RO pump will turn OFF.
If switch 1 and 2 are in the OFF Position (disabled), the left status LED will be a steady RED and the RO will not restart until the Power Switch has been manually cycled OFF then ON to reset the unit. If switch 1 is in the ON Position (auto reset), every 60 minutes the RO will start and stop again if a pressure fault continues.
If switch 2 is in the ON Position (pressure fault retry), the RO will attempt to restart after 30 seconds, then 5 minutes, then 30 minutes. If the pressure alarm has not cleared after the third try, the RO unit will remain off until manually reset.
If switch 1 and 2 are in the ON Position, after a pressure fault condition, the RO unit will continually attempt to restart after each 60-minute cycle, until the pressure switch input has cleared.

Initial System Start-Up

System Flush

Note: Direct permeate flow to drain for first 30 minutes of operation.

1. Connect the system to the appropriate electrical outlet, 110vac or 220vac 1 phase.
   Note: Follow all NEC and local electrical codes.

2. Ensure all plumbing connections are open to allow flow. Open Concentrate Valve (counterclockwise). CloseRecirc Valve (clockwise). Illustration 9 – Concentrate & Recirc Valve
   Ensure sufficient pressure (40 psi recommended) is in feed line. If pressure is less than 8 psi, the low-pressure switch will disallow start-up until pressure is adequate.

3. Press the Power button; the solenoid will open and the unit will start operating.

4. After water is flowing from the concentrate line, adjust the control valve to obtain designated flow for the specific model. (See Specifications Table – Page 6.)

5. Allow the unit to run for 30 minutes to ensure proper flushing of system.

6. After the flush time is over, press the Power button off.

7. Redirect the permeate line to the desired location.

Normal Operations

1. Turn the power back on. After the pump starts, adjust the control valve to the desired flow / pressure (not to exceed 150 psi).
2. The recycle valve may now be adjusted to achieve desired recycle flow rate, ensuring concentrate flow rate is as specified (Page 6).

CAUTION: To prevent concentrate from precipitating and causing irreversible fouling of the RO membrane, do not operate the system with the control valve CV2 completely closed. Also, do not exceed recommended maximum recovery.

Shutdown

1. Press power button to shut unit off. Close isolation valve, if installed on feed line.
2. If the unit is to be shut down for more than 1 week, a membrane preservative should be used. To accomplish this, perform 30 second flush using cartridge filter insert AMI No. C-C4210-A88. After 30 seconds, press Power button (Off) and close “Concentrate” valve. This will hold the preservative in the pressure vessel. (Complete instructions – Page 21.)
3. When the system is restarted after an extended shutdown, follow initial system start up procedures.

Maintenance Tips

Maintain proper operating conditions:

• Do not exceed 150 psi on the system inlet pressure gauge.
• Do not overuse recycle flow. This can cause premature scaling of the membrane. A proper concentrate flow is required for a long membrane life.
• To ensure no chlorine reaches the RO membranes, test the water from your carbon filter periodically for chlorine break through. To do this, a ‘bucket’ sample could be obtained by briefly removing the Feed TDS probe at the downstream side of the cartridge filters. Brief Power On/Off will be needed to perform this. See Component Identification photos – Page 9.

When To Change Cartridge Pre-Filters
Cartridge filters (both sediment and carbon) should be changed regularly to maintain proper pressure and flow. The carbon filter removes chlorine and will exhaust its capacity over time. This is dependent upon feed source concentration and flow rate. Check chlorine removal efficiency regularly.
Change the filters when the difference between the two cartridge filter pressure gauges increases by 10 psi – over the initial pressure difference. For example, if initial readings are 60 psi in / 58 psi out – the difference is 2 psi. So, when that difference reaches 12 psi – it’s time to replace the sediment and carbon cartridges.

When To Clean Membranes
In normal operation, the membrane in reverse osmosis elements can become fouled by mineral scale, biological matter, and grime. These deposits build up during operation until they cause loss in water output or loss of salt rejection, or both. Elements should be cleaned whenever the water output rate drops by 10 percent from its initial flow rate (the flow rate established during the first 24 to 48 hours of operation) or when salt content in the product water rises noticeably.
It should be noted that the water output rate will drop if feed water temperature decreases (about 1-1/2 percent per degrees Fahrenheit). This is normal and does not indicate membrane fouling. A malfunction in the pretreatment, pressure control or pump can cause a drop in feed water delivery pressure, feed water flow, or product water output, or an increase in salt passage. If such adjustments are needed, the element may not require cleaning.

Membrane Cleaning and Preservative Cartridges:

• Clean and Preserve Membranes without Removing them from your System.
• Reduce Downtime.
• Maintain Your System Performance at a Higher Level.
• Prolong Membrane Life by Regular Use of Cleaning Cartridges.

Temperature Correction Factor

The water temperature is one of the key factors in the performance of the reverse osmosis membrane element. The higher the temperature, the more the product flow, and vice versa. All reverse osmosis membrane elements and systems are rated at 77° Fahrenheit (25° Celsius).
To find the membrane permeate rate at a different temperature, follow these steps:

1. Find the temperature correction factor (TCF) from the below table.
2. Divide the rated permeate flow at 77° Fahrenheit by the temperature correction factor.
3. The result is the permeate flow at the desired temperature.

EXAMPLE
QUESTION: For a thin-film membrane permeate rated at 1800 gallons per day at 77º Fahrenheit, what is the actual permeate rate at 59º Fahrenheit?
ANSWER: Temperature correction factor (from below table) for 59ºF = 1.47
Permeate flow at 59 degrees Fahrenheit = 1800 ÷ 1.47 = 1224 gallons/day
