Product Introduction

LP series low pressure reverse osmosis membrane elements adopt the latest materials and production processes. They are membrane element products with high desalination rate, high water production and chemical durability. They are suitable for brackish water desalination, slightly polluted surface water purification, cooling circulating sewage reuse and other application fields with TDS value below 10000ppm.

Product Features

  • High Water Production
    High effective membrane area, high water production under low pressure operation;
  • High Desalination Rate
    High cross-linking degree of aromatic polyamide, dense desalination layer, and automated rolling process ensure high desalination rate;
  • Strong Chemical Resistance
    Can be cleaned with acid and alkali multiple times, with long service life.
