ESNA™ (Energy Saving Nanofiltration) Series

ESNA™ membranes can be operated at very low pressure, making them suitable for water softening and the removal of pesticides and pathogens. They can also remove iron and total organic carbon (TOC) while allowing monovalent ions, such as sodium and chloride, to pass through.

Features

ESNA membranes are capable of removing iron and organic matter while allowing monovalent ions, such as sodium and chloride, to pass through. This makes them ideal for drinking water production systems. Additionally, ESNA membranes can be operated at very low pressure, contributing to significant savings in operating costs and energy.

Applications

・Drinking water production
・Industrial wastewater treatment (mining wastewater)
・Organic matter removal

Model Type

Membrane Type Size Feature
ESNA1-LF2-LD-4040 4-inch ESNA1-LF2-LD 4-inch small type
ESNA1-LF2-LD 8-inch

High flow rate nanofiltration membrane with excellent natural organic matter (NOM) removal and moderate hardness removal performance, operating at pressures below 0.7 MPa. This design saves energy and reduces costs.
Additionally, the thicker feed spacer (34 mil) improves resistance to suspended solids in the feed water, reducing the frequency of cleaning and further lowering treatment costs.

ESNA4-LD 8-inch ESNA4-LD can be used to provide high quality permeate while removing certain contaminants such as nitrates and large organic compounds from water with low salinity.
Additionally, the thicker feed spacer (34 mil) improves resistance to suspended solids in the feed water, reducing the frequency of cleaning and further lowering treatment costs.
