The semi-permeable membrane for reverse osmosis applications consists of a thin film of polymeric material several thousands angstroms thick casted on a fabric support.

The commercial grade membrane must have high water permeability and a high degree of permeability. There are two major groups of polymeric materials which can be used to produce satisfactory reverse osmosis membranes; cellulose acetate (CA) and polyamide (PA).

The membrane manufacturing, operating conditions, and performance differ significantly for each group of polymeric material. QFS can manufacture custom designed RO plants for each unique application.

Membranes are sourced internationally to supply the correct RO membrane to the customer.

Please send us the detailed chemical analyses of the water to be treated with the flow and final quality requirements.
