Page 7: Description
/ dissolved impurities occurs during the RO process. Unlike a filter, which separates by “normal” filtration, the General Electric (GE) Osmonics membrane element sep- arates using a process called cross flow filtration. Feed water solution is separated into two streams, permeate and concentrate, and collected from both sides of the membrane element. -

Some operating definitions are provided to help you further understand your machine: Permeate Rate [Product Water Rate (Q passed through the membrane element and out of the membrane element housing; expressed in gal/min (gpm) or gal/hr (gph) [in metric, liter/min (Lpm) or cubic meters/hour (m /h)]. -

2.2.4 Permeate Outlet Connection Install the CIP valve on the permeate outlet tee. The pure water (permeate) should be transported to the point of use via non-corroding-type tubing, pipe, or hose. Examples are: food-grade flexible nylon tubing, stainless steel tubing, or PVC hose. -
Page 18: Preparation And Start-Up
If the machine is to be run at a different location than was originally intended, a new water analysis is required for warranty consideration and should be sent to GE Osmonics for review and recommenda- tions for operation of the machine. - Page 19 STEPS Re-check the function and integrity of your pretreatment equipment. Ensure that your water softener, activated carbon filters and iron filters (where applicable) have been leak-checked, backwashed, and thoroughly rinsed for service before starting up your RO unit. Attach the feed water pipe to the inlet of the machine. Check for leaks at all connection points.
- Page 20 inlet stream to the RO pump. It is important to balance the operating pres- sure and the respective flows of these valves to ensure that your machine is operating correctly. It is also important to understand the relationship of these two valves, the pressure gauge, and your RO pump. The pump has a fixed amount of flow produced, and the valves are the control devices to distribute this fixed flow amount.
- Page 21 NOTE: Do not allow the pressure to exceed 250 psi (17.2 bar). If the pressure exceeds 250 psi (17.2 bar), open the concentrate flow control valve until the pressure gauge shows 250 psi (17.2 bar) or less. As the machine purges the air and fills with water, the pressure will grad- ually increase.
-
Page 22: Machine Recovery
Once the desired flow rate is achieved [250 psi (17.2 bar) operating pres- sure] no further valve adjustment is needed. The table below shows flow rates at 50%, 66% and 75% recovery for the E4H models. Use this table in adjusting flow rates. NOTE: Permeate flow rates are dependent upon temperature and con- ditions at your site. - Page 23 A Daily Log Sheet (Section 10.0) which includes general operating con- ditions (pressures, flows, concentrations, pH, and pretreatment condi- tions), and routine or special maintenance (flushing or cleaning as need- ed) must be kept. This Daily Log Sheet will be required by GE Osmonics if a warranty question arises.

Page 24: Operation And Maintenance
OPERATION AND MAINTENANCE The operation and maintenance of your GE Osmonics E4H Machine is relatively simple but requires regular data recording and routine preventative maintenance. We cannot emphasize too strongly the importance of filling out the daily log sheet during each operating shift. A data sheet was filled out upon start-up containing pertinent facts on the operation of your machine. -
Page 25: Flushing
GE Osmonics recommends cleaning at least every month to ensure good membrane ele- ment performance and long membrane element life. GE Osmonics offers a full line of chemical cleaners for specific cleaning needs. See Table 4.4 (Dry Chemical Cleaners). Do not operate the machine below the designated pressure without approval from GE Osmonics. -

DO NOT use on CA membrane elements. Osmo ET-70 Cleaner intended to deal with sulfate or iron precipitation fouling. -
Page 27: Draining Machine For Shipment
The RO is now ready for operation. Draining Machine for Shipment Prior to shipping or outside storage of a GE Osmonics E4H Machine, the system should be cleaned with the appropriate cleaner, flushed with water, and protected from biological attack with the appropriate solution for TLC membrane. -
Page 28: Membrane Element Installation
Remove the tubing connections on the inlets and outlets of the membrane element housings. Open the concentrate valve. Remove the drain plugs from all PVC manifolds. Be sure the flow meters are drained by disconnecting the bottom fitting of each flow meter. -
Page 29: Membrane Element Replacement
Inspect the membrane element housing and clean as necessary to remove any con- taminants, obstructions, etc. Apply a small amount of O-ring lubricant to all O-rings on the end caps, and the brine seal on the membrane element. Insert the downstream end of the membrane element in the upstream end of the membrane element housing (i.e., load in the direction of flow;... - Page 30 Remove all the membrane elements from the membrane element housings in the direction of flow, where possible. If necessary, a membrane element can be removed against the direction of flow. A heavy duty pliers or channel lock pliers may be necessary to pull the old membrane element our of the membrane element housing.

OPTIONAL ACCESSORIES Level Controls Float switches, pressurized storage switches or other level controls should be wired into the control circuit line prior to the switch on the unit. The following ensures that the inlet valve, instruments, and pump are not powered when storage tanks are full: float switch assembly with cord, counterweight, and plastic float (used with an atmospheric storage tank). -
