The unique chemical and physical properties that can be displayed by polypropylene and its copolymer derivatives are enabling its development as a truly versatile material for water filtration. Well known applications include spiral wound cartridge filters commonly used for household water or the office drinking fountain, to pressure membranes that provide micro, ultra or nano size filtration barriers, whilst needle-felt or woven cloth filter belts or inline pressure bag cloths are well known to the hydro metallurgist and process engineer._x000D_
A relatively new filtration concept that is generating interest and applications across all industries including the mining sector involves use of a unique fabric type filtering media made from polypropylene fibres. This technology not only has a vastly wider window for potential applications, it delivers an attractive cost saving alternative to the traditional sand media or diatomaceous earth type filters, along with potential benefits for integrated filtration units._x000D_
This paper discusses the proven potential of the fabric media technology with examples of performance comparisons and confidence gained from full scale operating installations at mine sites and other locations._x000D_
