OPERATING INSTRUCTIONS LC Manual 11/02 Rev. 3 H. Set the percent rejection alarm setting to 90%. I. Check for plumbing leaks and make appropriate repairs as necessary. All systems are leak checked at the factory but vibration during transit can cause new leaks to develop. J. Once the system is checked out and operating correctly, place the controller in the desired mode. Read the next section on initial flushing before directing product water to the water storage tank or user system. 3.3 INITIAL FLUSHING OF THE SYSTEM Since the RO membranes are shipped with sodium bisulfite preservative solution, initial flushing of the system is required. Before operating a new system, and also after the replacement of a RO membrane, perform the following steps: A. Direct the product water to a convenient drain. B. Ensure a steady feed water supply, turn on the system pump and let the system run for four hours. This will flush residual bisulfite solution and any particulate impurities from the membranes, housings and plumbing of the system. C. Product quality will increase slowly for 1 hour. Monitor the inlet quality vs. the product quality by observing the conductivity meter outputs. NOTE: The system should have better than 90% rejection within 2 hours as the membranes equilibrate. If the product quality does not improve, refer to section 5.0 Troubleshooting. D. After flushing product to drain for a minimum four hours, turn off the system and reconnect the product line. The system is now ready to be put into a normal operating mode. Refer to the Product Description/Equipment Specifications in the Appendix for design flowrates and pressures. 3.4 NORMAL OPERATIONS The following procedure is for operating a USFilter Reverse Osmosis System that has been installed and initial flushing has been completed. Refer to the MC10 Controller manual in the Appendix for detailed instructions. Use this section for daily startup or to restart the system after a short-term shutdown. A. BEFORE starting the RO unit, verify that the following conditions exist: DEVICE CONDITION Pump discharge throttling valve 1/4 to ½ OPEN Reject throttling valve ¼ to ½ open Reject recirc throttling valve 1/8 to 1/4 OPEN Any valves in the reject to drain line OPEN Any valves in the process supply line OPEN Pre treatment equipment ready for use 3-2 USFilter
LC Manual 11/02 Rev. 3 OPERATING INSTRUCTIONS Storage tank (if applicable) ready for use IF ALL THE ABOVE CONDITIONS EXIST, THE SYSTEM IS READY TO START. IF ONE OF THE SETTINGS IS INCORRECT, CORRECT THE SETTING PRIOR TO PROCEEDING. B. Verify the Controller is set to the proper operating mode, either TANK FEED or DIRECT FEED as described in the MC10 RO Controller manual in the Appendix. C. Press the SYSTEM START button on the Controller. This will start the system. The inlet solenoid valve will open then the pump will start after a 15 second delay. D. Verify that the product, reject, and reject recirculation flows are correct. If not, adjust the pump discharge throttling valve and the reject and reject recirculation valves. Refer to the Product Description/Equipment Specifications in the Appendix for design flowrates and pressures. Adjustment procedure: First, adjust the unit to make the correct amount of RO product water by adjusting the system pressure. This can be accomplished by regulating the pump discharge throttling valve. Further open the valve to increase the system operating pressure and productivity, further close the valve to reduce the system operating pressure and productivity. Second, adjust the unit to make the correct amount of reject to drain flow by adjusting the reject throttling valve. Open the valve to obtain a higher flow rate or close the valve to reduce the flow rate. Third, adjust the unit to make the correct amount of reject recirculation flow by adjusting the reject recirculation throttling valve. Further open the valve to obtain a higher flow rate or close the valve to reduce the flow rate. NOTE: This is somewhat of a "balancing act", in that as you close the reject valves, the product flow increases and the reject flow decreases. As you open the pump discharge-throttling valve, the product and the reject flows increase. You may have to adjust the pump discharge-throttling valve to reestablish the operating pressure to obtain the correct product flow as established in the first step. E. Once the RO unit is operating at the parameters outlined in this manual, record the operating parameters on the “RO Data Collection Form” as described in Section 4.4, and found in the Appendix. It is imperative to record the operating parameters daily, since RO trouble shooting may require a trended analysis of the RO operating parameters. NOTE: If the RO will not start, or can not achieve the correct flows, go to the trouble shooting section for more information. USFilter 3-3
