Membrane Filters Manufacturers

Membrane Filters are thin polymeric structures with extraordinarily fine pores. These sheets of highly porous material are composed of pure, biologically inert cellulose esters or other polymeric materials. They remove from a gas or liquid passing through them all particulate matter or microorganisms larger than the filter pores. They are available in a wide variety of pore sizes in a number of different materials. There are two types of membrane filters: surface and depth. Surface type filters are used for final filtration or prefiltration, whereas depth type is used in clarifying applications where quantitative retention is not required. Membrane filters are used in liquid, as well as air and gas applications. Membranes are typically made from a thermoplastic material such as PTFE, or a synthetic polymer such as cellulose acetate.
