PSI MEMBRANE® Pro-BW Brackish Water Membrane is a third-generation nanocomposite membrane (TFN) reverse osmosis membrane element that features unique anti-fouling technology. This technology not only offers superior anti-fouling and cleaning performance but also ensures an exceptional salt interception rate, reduces energy consumption, and extends the cleaning cycle.
1. Special coating to prevent microbial growth, significantly reducing membrane pollution.
2. Resistant to cleaning agents, ensuring long-term stable operation.
3. Anti-fouling coated surface enhances performance and extends the membrane's service life.
4. Product flux is 30% higher than traditional TFC membranes, with notably lower energy consumption.
