Filter belt screen filtration is a physical separation process in which a gas or liquid containing solids passes through a porous belt medium, which retains the solids. This process may operate in a batch or semi-continuous mode, regular removal of retained from the filter medium. An initial layer of filter cake must form at the beginning of the filtration operation.Filtration systems may also be designed to operate in a continuous manner. As with other filtration techniques, an accumulating solid cake performs the bulk of the filtration.

         

Filter belt screen filtration effectively controls environmental pollutants in gaseous or liquid streams. In air pollution control systems, it removes dry particles from gaseous emissions; in water pollution control, filtration removes suspended solids; in solid-waste disposal, filtration concentrates solids, reducing the landfill area required. Often, filtration processes simultaneously reduce air, water, and solid-waste disposal problems. An air pollution control system might, for example, remove particles and/or gases from an emission source and might consist of a scrubbing device that removes particulates by impaction and the gases by chemical absorption.

The reaction products of gases and chemical can produce a crystalline sludge. A fabric filter may also be used to remove solids from water so that the water can be recycled. Therefore, sewage sludge doesn't present a water pollution problem. Effective use (optimization) of a fabric-filter system would minimize problems with waste disposal.

Press filter fabric have the characteristics of good water permeability, air permeability and non-revealed sludge, acid-resisting and alkali-resisting. Because of their designing structure, the sludge can be peel off easily from the filter cake, so the filter belt creen are easily cleaned and have a long working time.
