Product Introduction

ULP (Ultra-low pressure) ultra-low pressure reverse osmosis membrane elements are high water production and high desalination rate membrane element products developed by Bishuiyuan for desalination of surface water and groundwater. They have the characteristic of achieving high water production at lower operating pressure, which can greatly reduce system operating costs, while reducing investment costs for pumps, pipelines, vessels and other equipment, improving economic benefits. They are suitable for desalination fields such as brackish water, surface water and tap water with TDS value below 2000ppm.

Product Features

  • High Efficiency Filtration Effectively removes heavy metals (lead, arsenic, etc.), bacteria, viruses, organic pollutants and dissolved salts;
  • High Water Production Can achieve high water production and desalination rate at lower operating pressure;
  • Strong Chemical Resistance Can be cleaned with acid and alkali multiple times, with long service life.
