Products > membrane > Large Hollow Fiver Module Because of the use of cellulose acetate (CA) with high hydrophilicity, the membrane surface is less subject to contamination, and therefore high stable permeability is maintained. In addition to water purification, these models are widely used for recycling wastewater in the industry. * Easier handling * High corrosion resistance(All resin made） * Light weight・Compact type * Easy connection with using the victoric joints * Cellulose acetate (CA) membrane with high hydrophilicity provides stable, high permeability. * Dead end filtration is available according to the feed water condition. * Composed of acetate and celluloses of natural origin, cellulose acetate (CA) is an ecofriendly, biodegradable substance, and can be disposed of as waste without concern. * Because its membrane surface is negative charged, it is less susceptible to deposits of negative-charged particles, thus keeping high permeability. * The cartridge type designed with a separate housing saves waste. * Economical-cost is greatly reduced. * Cartridge now in a larger size (6 inches) * Choice of cartridge case material according to the application:   FK20---Heat-resistant type (Case made of polysulfone)   FN20---For use in ordinary temp. (Case made of polyvinyl chloride)
