This slide presentation outlines a case study of the Bonita Springs, Florida, Reverse Osmosis (RO) Water Treatment Plant (WTP) that compared full-fit vs. fiberglass reinforced plastic (FRP) wrapped membrane elements. GE Water Technologies offered Bonita Springs Utilities (BSU) similar brackish water membrane elements with the option of a traditional fiberglass reinforced plastic (FRP) wrap or in a newly released municipal full-fit version. BSU loaded traditional FRP-wrapped elements in two trains (Train #1 and #2) and full-fit elements in two trains (Trains #3 and #4) to allow side-by-side comparison. Both sets of membrane elements have been operating successfully for more than two years. Topics covered include: full-fit membrane element discussion; BSU operational data; BSU feed pressure data; BSU differential pressure data; BSU Permeate TDS Data; membrane element performance; and, BSU Operating Cost Comparison. Includes figures.
