Some operating definitions are provided to help you further understand your machine: Permeate Rate [Product W ater Rate (Q p )] is the flow rate of purified water which has 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 3 /h)[...]

Flow Description - The feed water passes through a replaceable 5-micron cartridge pre-filter which removes bulk suspended solids. Filtered water then flows to the inlet con- trol valve. This solenoid-controlled diaphragm valve is wired to the ON/OFF switch and opens when the machine is turned ON, allowing water to flow to the pump inlet. When the m[...]

10 2.0 INST ALLA TION 2.1 Mounting E4H machines are equipped with a stand alone frame, 61-inch (155-cm) H x 132-inch (335 cm) W x 34-inch (86 cm) D, which supports the machine. At least 45 inches (1 14 cm) of space should be allowed on each end of the membrane element housings for removal and loading of membrane elements. If 45-inches (1 14 cm) are[...]

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. The permeate outlet is 1-inch FNPT . 2.3 Electrical The DLX and ECN [...]

3.0 PREP ARA TION AND ST AR T -UP 3.1 Pretreatment for W ater Purification All systems will operate most efficiently on filtered water with a pH of less than 6.5 and a Silt Density Index (SDI) of 5 or below . If the machine is operated on higher pH water , other forms of pretreatment may be necessary . A water analysis prior to start-up of the mach[...]

STEPS 1. 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. 2. Attach the feed water pipe to the inlet of the machine. 3. Check for lea[...]

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[...]

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. Y ou should see water flowing through the permeate a[...]

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. Contact your dealer[...]

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. 17[...]

18 4.0 OPERA TION AND MAINTENANCE The operation and maintenance of your GE Osmonics E4H Machine is relatively simple but requires regular data recording and routine preventative maintenance. W e 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 cont[...]

4.3 Flushing The machine should be flushed at least daily to remove sediment from membrane element surfaces. T o flush the unit: STEPS 1. Open the concentrate valve until the pressure gauge indicates the minimum pres- sure designated on the nameplate. This increases the flushing action on the mem- brane element. NOTE: If pressure will not decrease [...]

T able 4.4 Dry Chemical Cleaners CLEANING PROCEDURE STEPS 1. W ith the RO machine running, open the Clean-In-Place (CIP) permeate valve. After this valve has been opened, close the permeate service valve. Permeate water will flow into the CIP tank. Allow the water to run through the CIP tank and the CIP tank drain valve for a few minutes to ensure [...]

4. T urn the CIP ON/OFF switch to the ON position and recirculate the cleaning solu- tion through the machine. The cleaning solution should be recycled for approxi- mately 15 minutes or until the solution temperature reaches 85°F (29°C). If heat rise occurs too quickly , larger volumes of cleaning solution or the use of a heat exchanger will slow[...]

3. Remove the tubing connections on the inlets and outlets of the membrane element housings. 4. Open the concentrate valve. 5. Remove the drain plugs from all PVC manifolds. 6. Be sure the flow meters are drained by disconnecting the bottom fitting of each flow meter . 7. Allow the machine to drain for a minimum of eight hours or until the opened p[...]

7. Inspect the membrane element housing and clean as necessary to remove any con- taminants, obstructions, etc. 8. Apply a small amount of O-ring lubricant to all O-rings on the end caps, and the brine seal on the membrane element. 9. Insert the downstream end of the membrane element in the upstream end of the membrane element housing (i.e., load i[...]

2. 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. 3. T o reinstall replacem[...]

5.0 OPTIONAL ACCESSORIES 5.1 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,[...]
