Hydranautics RO Membrane - Low Energy - ESPA-2540

Hydranautics ESPA-2540 series low-energy reverse osmosis membranes are suited to brackish water and mains water applications. 

Manufacured from high quality composite polyamide membrane, these membranes operate at standard operating pressure of 150 psi, while maintaining a typical rejection rate of 99.4% (98% minimum)

Delivering a permeate flow rate of up to 750 gpd (2.84 m³/d), this membrane is suited to both municipal and light brackish water applications.

Membrane Dimensions: 2.4" x 40" (2540)

How an RO membrane works:

The spiral membrane is constructed from one or more membrane envelopes wound around a central collector tube. The pure water (permeate) passes through the membrane in the envelopes and spirals inwards to the collector tube and is diverted to the storage tank.

The waste water (concentrate or brine) carries all the impurities in the water and is discharged to drain.
