What is the wedge wire screen ？ As a filtering element, wedge wire screen, know as the wedge wire silk screen or T-shaped screen , is manufactured by the welding of the surface wire and support wire with special techniques. The surface were has a requirement of precise size ans is welded to the support wire with a precise clearance. It have the flat mesh and cylindrical type in structure. Why is the wedge wire screen selected The filtering element plays a crucial role in the filtration equipment. The filtering element of wedge wire screen can meet the requirements of high precision and strength.Besides high precision and strength、non-clogging, the use of it in the automatic back-washing equipment can make the equipment change the filtering element without a pause and improve the efficiency. High precision+ high strength+non clogging +high efficiency = cost reduction The wedge wire screen has two bases structure, one is flat mesh shape and the other is wire wrapped screen (johnson screen) , these two type can make out almost full shape ans size wedge wire filteration parts. In filtration, the solids are blocked and deposited on the smooth surface, forming a filter cake which can block smaller solid particles. The unblocked tiny particles will not obstruct the V-shaped slot. The inverted water(gas) clears the filter cake and dirts from the surface of the filter element.
