The HQ-RO/SW seawater desalination membrane is a spiral-wound polyamide composite reverse osmosis membrane element. Its unique anti-fouling membrane technology endows it with excellent anti-fouling capability and cleanability. While ensuring high salt rejection performance, it reduces energy consumption during operation and extends the cleaning cycle.

The wide flow channel reduces the probability of membrane fouling and improves the cleaning effect.
The chemically stable and cleanable membrane ensures long-term, reliable operation.
The TFC (Thin Film Composite) surface is coated with a super anti-pollution layer, which has excellent anti-pollution performance and a long service life.
The membrane has a high permeability and lower energy consumption.
