LC Manual 11/02 Rev. 3 SYSTEM MAINTENANCE A. Feed water 1. Check pressure daily; record weekly. Adjust as necessary to maintain 15 to 50 psig (minimum 25 psig recommended). 2. Monitor feed and product conductivity and record weekly. 3. If there is a possibility of the presence of chlorine in the feed water, measure free chlorine weekly. (It must be non-detectable or the membranes may be damaged). 4. If there is a possibility of significant pH variations (i.e. the feed is pH controlled) monitor and record pH weekly by independent pH meter or litmus paper. 5. Measure total hardness monthly. 6. Measure total alkalinity monthly. B. Prefilter C. Pump 1. Measure differential pressure daily; record weekly. 2. Change prefilter cartridge when the differential pressure is greater than 10 psi or every month, whichever occurs sooner. 1. Check pressures daily; record weekly. 2. If the pressures have fallen off, check product, reject and reject recirculation flow rates. D. Conductivity 1. Observe feed and product conductivity daily; and record weekly. 2. Record percent salt rejection weekly. Conductivity Feed - Conductivity Product 100 X = % Rejection Conductivity Feed E. Flow Rates 1. Check daily and record product and reject flow rate weekly. 2. Calculate the percent recovery using the following formula: Product Flow Rate 100 X = % Recovery Product Flow Rate + Reject Flow Rate The percent recovery should not exceed the design value shown on the Equipment Specifications sheet in the Appendix. If minimizing water usage is critical, the percent recovery should be maintained near, but not above the maximum value. Operating with too high a percent recovery will lead to premature fouling of the membrane. USFilter 4-9
SYSTEM MAINTENANCE LC Manual 11/02 Rev. 3 F. Bacteria 1. For critical applications, such as dialysis and pharmaceuticals, measure the number of bacteria in the product water weekly. Record the results as colony forming units per milliliter (CFU/ml). Sanitize as necessary. 2. For non-critical applications, measure the number of bacteria in the product water monthly. Record the results as colony forming units per milliliter (CFU/ml). Sanitize as necessary. G. If the maintenance log shows steady deterioration in results (product flow, percent rejection, etc.) corrective action should be taken. (Described in Section 5.0 Troubleshooting.) 4-10 USFilter
