PSI MEMBRANE® Pro-BW Seawater Desalination MembraneIntroducing the third-generation nanocomposite membrane (TFN) reverse osmosis element, Pro-BW. With its unique anti-fouling technology, this membrane ensures superior anti-fouling and cleaning performance. It guarantees a high salt rejection rate while significantly reducing energy consumption and extending cleaning cycles.
1. The wide flow path design minimizes the risk of membrane fouling, resulting in improved cleaning efficiency.
2. Enhanced cleaning resistance ensures stable long-term operation.
3. The anti-fouling coating on the surface enhances performance and extends the membrane's service life.
4. The product offers 30% higher flux compared to traditional TFC membranes while consuming less energy.
