Product Introduction

BW (Brackish Water) series brackish water reverse osmosis membrane elements are suitable for complex water quality brackish water and industrial wastewater treatment applications with TDS value below 10000ppm. They have a relatively wide cleaning pH range (1~13), which can quickly and effectively solve membrane element fouling problems. The product has won the "China Patent Award".

Product Features

  • High Desalination Rate Suitable for high salinity feed water quality;
  • Strong Anti-Fouling Performance Unique anti-fouling coating technology combined with 34mil wide feed spacer design can ensure normal use of membrane elements under extreme conditions;
  • Strong Chemical Resistance Can be cleaned with acid and alkali multiple times, with long service life.
