The size of the CIP container should be a minimum of three times the permeate rate. When set properly, the RO machine, the CIP pump, and the CIP container should be assembled in a loop configuration to recirculate the water through the machine and back to the container during cleaning. The size of the CIP container should be a minimum of three times the permeate rate. N GE recommends the use of a CIP or booster pump to provide the proper feed water pressure and quantity to the RO machine during cleaning. Figure 2.5 Clean-In-Place Pump and Tank Hook-Up With the machine set-up in the CIP configuration and the cleaning solution mixed in the container, you are now ready to start the CIP process. Follow the Steps below. STEPS 1. Check to ensure that the feed, permeate, and concentrate valves and line are open and unrestricted in the tank loop. 2. Start the CIP and RO machine pumps together. As they start up, observe all RO machine pressures and flows. 3. Recycle the cleaning solution for about 15 minutes. Damage may result to membrane elements if the temperature of the CIP solution exceeds 105°F (40°C). If the water temperature exceeds 100°F (38°C), place bags of ice into the CIP container to absorb the extra heat. 4. After recirculating the cleaner for 15 minutes, shut down the RO and the CIP pump. 18 5. Let the CIP solution dwell in the machine for 20 minutes. 6. After the 20 minute dwell time, start the CIP recirculation process again for 10 minutes. 7. After the 10 minute recirculation time is complete, de-energize the machine. Then, open the inlet water line and route the concentrate and permeate lines to the drain. 8. Start the RO machine and flush to drain for 20 minutes. Verify the permeate quality is good before returning to normal operation. 9. After permeate quality is verified as good, route the permeate to point of use and concentrate to drain. You are now ready for normal operation. 2.20 Suction Cleaning GE does not recommend the suction cleaning method to clean the E4-Series RO machine. If using suction cleaning, reference cleaning with a CIP pump above (Section 2.19.2, Procedure to Clean with a CIP Pump). STEPS 1. Arrange the RO and the CIP container in a closed loop situation with the cleaning solution, reference Section 2.19 (Membrane Element Cleaning). 2. Move the L1 and L2 wires on the pressure switch across to the motor terminals (Figure 2.1, Three Phase Allan Bradley Motor Starter). The wires can also be temporally jumped. 3. Open the inlet feed valve. 4. Start the RO machine 5. As the machine starts up on inlet feed water, slowly close the inlet feed water valve while slowing opening the feed water valve to the CIP tank. You will begin to hear the RO pump draw the CIP solution into the machine and circulate it back into the CIP tank. After achieving prime, observe the RO closely to ensure that you do not loose pump prime, which may result in pump damage. 6. Refer to the CIP cleaning procedure (Section 2.19.2) for cleaning steps. WARNING: LOSS OF PRIME DURING SUCTION CLEANING MAY RESULT IN SERIOUS DAMAGE TO THE PUMP. 19 NOTE: As previously mentioned, the manufacturer recommends use of a CIP or booster pump to circulate the cleaning solution during membrane element cleaning. 7. After suction cleaning cycle is complete, reopen inlet water and flush machine to drain for twenty minutes. 8. After permeate quality is verified as good, return machine to normal operation mode. 2.21 Changing Out Membrane Elements CAUTION: Replacement membrane elements are shipped from the factory in a plastic bag with a small amount of bactericide solution to prevent biological growth. When installing the membrane elements, always provide adequate ventilation and wear gloves while handling the membrane elements as recommended. The membrane elements must be kept moist at all times in to prevent possible damage to the membrane element material. STEPS 1. Remove the top end caps and clamps from the membrane element housings. Lubricate all O-rings and brine seals, and the PVC membrane element stems (stingers) with a non-petroleum based lubricate (i.e., glycerin or poly water). 2. Load the down flow membrane elements first, by inserting the membrane element into the membrane element housing with the brine seal end of the membrane element up. Slowly turn the membrane element as you lower it into the membrane element housing. As you reach the bottom of the housing slowly guide the PVC stem or stinger on the end of the membrane element into the head of the end cap. As the membrane element slides into the housing the brine seal will be on the top. 3. Next, load the up flow membrane elements, by lubricating all brine seals, O- rings, and the membrane element stingers. With the up flow membrane element and the brine seal will be on the bottom of the membrane element. Turn the membrane element slowly as you lower it down into the housing. As with the down flow membrane element, one must slowly guide the PVC stinger on the end of...
