Membrane Troubleshooting Guide
The following chart illustrates the procedure for determination of RO membrane
performance. However, the chart represents only rough guidelines for determin-
ing performance of RO membrane. Depending on your tap water chemistry, the
rejection characteristics of the membrane may vary significantly.
