Sea Water Desalination Membrane Elements

INTRODUCTION

Aromatic polyamide composite SW series membrane elements is newly developed for seawater desalination or treatment for raw water with high salinity, with stand high pressure.

It is mainly used for seawater or raw water with high salinity > 10000mg/L; Its application fields include seawater desalination, RO concentrated water reuse, zero liquid discharge for high salinity wastewater, materials concentration and so on. It has the characteristics of high desalination rate, stable performance and high flux.
