Evaluation of Cleaning Spiral Wound Membrane Elements with the Two-Phase Flow Process

Novaflux Technologies, Inc.; Princeton NJ. June 2003

Report #101 - Summary -

A protocol to achieve the cleaning of 8" spiral elements using the Novaflux two-phase patented method has been established and validated. The technology has demonstrated capability of significantly improving the flux of 8" spiral elements, and decreasing presure drop between the two ends of the modules to acceptable levels. In addition, the two-phase flow process was systematically validated for cleaning 2.5" and 4" spiral elements in series using a short 10-minute cycle.
