Selection of filtering cloth

Main function of the filtration medium is to separate the solid particles out from the flowing liquid by consuming minimum energy. 

Effective filtration, to a large extent, depends on proper selection of applicable filtration medium, the customer may refer to those technical specification and information as results of research efforts and experience of the industry concerning performance and selection of filtration medium, however, to select the filtration medium, relevant experiments and tests shall be conducted to the solid and liquid mixture to be separated extremely carefully as a tiny change in process of experiments/tests might bring major impact to the results.

Diversity of the filtration medium makes it a hard job to select the proper applicable one, you can hardly define which filtration medium is the most applicable for the specific separation operation simply by referring to its particle size and size distribution, in fact, change of particle concentration and shapes will make your decision of filtration medium harder. 

Woven filter cloth and non-woven filter cloth made of polymeric material:  Polypropylene, polyethylene, polyester, polyamide, polyvinyl chloride and others.

        Single wire double-layer composite filter cloth: It’s a double-layer filtering medium, with satin weave texture on smooth surface of the top layer, such smooth surface may be subject to matting treatment for improvement. The bottom layer is made of single wire woven cloth of higher strength which is supportive and helpful for discharging. Particles penetrating or passing through the top layer would not be retained there resulting in clogging, instead, it will flow down along the funnel in between the top layer and bottom supportive layer, which is good for regeneration of filtering cloth.   

Metal net or mat sheet could be selected as filtering medium for large particle solid to achieve higher filtering efficiency.
