Low-Energy Membranes

Benefit from 100-150psi operating pressures and 98-99% rejection

Low pressure reverese osmosis membranes operate at low pressures of 100-150 psi (7.9 - 11.9 bar) while maintaining typical rejection rates of 98-99%

Fast becoming the new industry standard, these elements combine low operating pressures and excellent permeate production and rejection rates, these membranes offer reduced energy consumption, lower operating costs and reduced wear and tear.

Available in a full range of 2.5-inch and 4.0-inch commercial sizes and from a variety of trusted brands, Aquastream delivers across Australia directly to industry partners.
