BWB reverse osmosis systems are used for treating most bore water types, for treatment of feedwaters with TDS values up to 10,000ppm, or where a permeate flush feature is required.
RO pressure vessels are FRP high pressure types with high performance membranes and the open frame is electro-polished 304 grade stainless-steel.
