Hydronautics CPA5-LD series reverse osmosis membranes are suited to brackish water applications and incorporate Low Foulding Technology
Manufacured from high quality composite polyamide membrane, these membranes operate at standard operating pressure of 225 psi, while maintaining a typical rejection rate of 99.7% (99.5% minimum) and are able handle high TOC, hardness and silica levels.
Combining the latest 'Low Fouling Technology' of thicker feed spacer channel and treated with biofouling and colloidal resistance properties, these membranes offer longer service life while maintaining high rejection rates.
The CPA5-LD-4040 membrane is suited to applications including drinking water, boiler make-up water and ultrapure water for semiconductor manufacturing.
Membrane Dimensions: 3.95x40" (4040)
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.
