Textile filter belt screen are an essential part of countless industry processes, contributing to product purity, savings in energy/production costs and a cleaner environment. This paper describes, in general terms, the factors which are taken into account when designing a filter belt screen for a solid-liquid separation process, touching on textile raw materials and, with particular reference to filtration and filtration equipment considerations, the elements of cloth constructions and finishing procedures.

        

In the last 20 years the European Community has introduced more than 100 legal regulations in the area of environmental protection, the majority of which are directed towards the control of environmental pollution. It is, therefore, not surprising that industry should look to filtration technologies to assist in meeting the increasingly stringent statutory requirements, but, in addition, industry is also looking to the same technologies for both technical and economic reasons. The technical reasons include aspects such as improved product quality whereas economic aspects may be in respect of shorter process cycle or reduced manning levels or perhaps drier filter cakes and therefore the need for less thermal energy in subsequent processing.

This paper reviews some of the factors which are taken into account when selecting or designing a filter belt screen for a particular application. The types of raw material available are described, Together with some basic polyester mesh constructions and finishing processes. Suggested procedures for fabric evaluation are also briefly examined.
