Case study of a brackish water Reverse Osmosis plant in Virginia which has been in operation on original membranes for eleven years will be presented. The raw water from wells has a high silica content. Various blending scenarios were investigated during study phase. The plant final design was based on optimum bypass blend, which has been proven to be the best option after 11 years of successful operation. Proper custom formulated scale inhibitor to minimize silica fouling/scaling will be also discussed.
