Hydranautics 4" Nanofiltration Membranes

Hydranautics nanofiltration membranes are first-rate nanofiltration membranes that have been specifically manufactured for water softening utilization, and the eradication of biological organisms such as bacteria, viruses etc.

Hydranautics nanofiltration membranes are designed to eliminate large percentages of carbon and iron, while allowing the crossing of ions such as sodium and chloride. In addition, these membranes coupled with the unique features of ESNA provide large savings in power & energy costs. These benefits have allowed Hydranautics nanofiltration membranes to be the most widely used elements for municipal clean water systems.

Hydranautics nanofiltration membranes effectively remove more than 92% salt rejection through low pressure performance and power & energy usage, which greatly reduces installments and operation expenses. These membranes clean organic material with maximal productivity in order to prevent the accumulation of impurities within feed waters. For this reason ,they are viewed as the perfect membrane based water softeners. The benefits provided by Hydranautics ESNA membranes consist of:

  • Up to 92% salt rejection
  • Eradication of organic substances
  • Optimal hardness rejection
  • Ultra low pressure and power & energy savings
  • Lower OPEX
  • Utilization of advanced technology for maximum productivity and easy cleanability
