Membrane Chemicals

As a leading supplier of reverse osmosis system we have bridged the gap between equipment supplier and formulator. The reverse osmosis membranes have such small pores, it is extremely important to provide a feed stream free of suspended impurities and stablised to prevent precipitation or scaling reaction. The susceptibility of the membrane to fouling by water borne debris is measured by a special filteration technique that determines the silt density index (sdi).  

because of high fouling rate of membranes, water with negative langelier index is feed into the system. Chemical cleaning is an integral part of the membrane maintenance program. The procedure must be matched to the nature of the deposit and may include detergent, biocide. Acids and alkalies.
