Membrane 4040

LCM reverse osmosis membrane is a thin film composite membrane made of three layers. A bottom poly ester support web. A middle microprous support layer composed of polysulphone and an ultrathin top barrier layer of poly amide. A micro porous layer of poly sulphone is cast In to the web surface with partial penetration of polysulphone in to the polyester web.
The Lexcru TFC membrane is an aromatic polyamide made from meta phenylene diamine and tri acid chloride. Lexcru membranes are chemically stable enabling multiple chemical cleaning. The thickness of barrier layer is nearly 200 nanometer .The moderate thickness of barrier layer make these membranes strong and stress resistant. Lexcru membrane sheets are less susceptible to fouling due to fouling resistant protective coating over it.
