MEMBRANE WASHING CHEMICALS

The most common chemicals used for membrane cleaning are Acid and Alkali based. Acidic cleaners are used to remove iron and inorganic residues and should be made at a pH of about 2-3. Alkaline cleaners are used to remove biological materials, organic and silica residues and should be made at a pH of about 10-11.

MEMBRANE WASHING PROCEDURE

You may experience performance degradation due to the buildup of debris on the surface of Reverse Osmosis membranes. Mineral deposition, colloidal particles, biological material and insoluble organic compounds are the usual causes of membrane contamination. Membrane washing should be performed when the production capacity decreases by 15% or the differential pressure increases by 15% under normal operating conditions. See the operating instructions for more information.
