Prototype High-Temperature Chlorine-Resistant RO Elements. Test and Demonstration Report. Phase 1
Abstract
The overall objective of this test is to generate reverse osmosis performance data documenting the performance of a new membrane element prototype designed for improved resistance and high temperature operating characteristics. The specific objective fo this Phase I test is to provide baseline test data on these prototype elements under three feedwater test conditions (fresh water, brackish water, seawater). These baseline test data are to demonstrate minimum flux and chloride rejection characteristics as a basis for approval to conduct Phase II and III tests. Sixteen prototype spiral wound reverse osmosis elements were designed, fabricated, and subjected to an extensive Phase I test protocol for acceptance. These prototype elements contained a high rejection grade of FilmTec's FT30 membrane especially treated by a propertied process to enhance its chlorine resistance. Spiral elements were additionally designed ot operate at a feedwater temperature of 140 F. Flux and salt rejection of these elements averaged 2220 GPD and 99.0% of ASTM synthetic seawater at 800 psi and 25 C.
