Membranes cannot function properly as a result of calcium, fungi, polymers, silica, sand and pollutants formed on the membranes blocking the pores on the membrane surfaces. For this reason, Tetra membrane washing systems are used to open the membranes and allow the water to pass again and perform the purification process.
Tetra Membrane washing system is designed to be controlled manually with the panel on the chassis. The chemical storage tank is mounted on the chassis. It is connected by PVC pipe and fittings. Before shipment, all wiring and piping is completed and tested in our factory and shipped.

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 done at a pH of about 2-3. Alkaline cleaners are used to remove biological materials, organic and silica residues and should be done at a pH of about 10-11.
MEMBRANE WASHING PROCEDOR
You may experience performance degradation due to the accumulation of residues on the surface of Reverse Osmosis membranes. Mineral precipitation, colloidal particles, biological material, and insoluble organic compounds are the usual causes of membrane contamination. Membrane washing should be done when the production capacity decreases by 15% or if the differential pressure increases by 15% over normal operating conditions. See the operating instructions for more information.
