SOME ASPECTS OF THE DESIGN OF FILTER FABRICS FOR USE IN SOLID-LIQUID SEPARATION PROCESSES

Textile filter fabrics are an essential part of countless industrial p rocesses, contributing to product purity, savings in energy/production costs and a cleaner environment. The paper describes, in general term s, the factors which are taken into account when designing a fabric fo r a solid/liquid separation process. It briefly discusses textile raw materials and, with particular reference to filtration and filtration equipment considerations, the elements of cloth constructions and fini shing procedures.
