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