The API® Parallel Belt Filter is suitable for treating water where the solid content is made up of foliage, small material and detritus that are difficult to intercept with grill systems. It is particularly suitable for large level excursions. In the mat filter the filtering mesh is made up of a special strip of stainless steel with a particular profile with a passage of 50x2 mm or 50x4 mm, depending on the filtration requirements. When the filter is immersed, the water to be filtered passes through the mat from the outside towards the inside, leaving the retained material on the surface, which is then removed by backwashing and using pressurised water jets. The operation of the belt filter machine is electromechanical by means of a gearmotor unit which acts on a drive drum and return drum. The filter frame is hot-dip galvanised for outdoor installation and is equipped with a control system and external electrical panel with PLC for automatic or manual operation.
