Bag filtration works by the principle of pressure filtration. The substance to be filtered is pumped from the inside out within the bag filter, in such a way that the impurities remain in the bag and the clean substance is evacuated through the bottom of the filter holder.
Bag filter system is designed for optimum filtration performance. In the process industry, it provides filtration solutions for a wide variety of fluid applications. Large volumes of high viscosity liquids can be filtered with them effectively. In general, bag filters consist of filter housings, filter bags, inner support cages, positive sealing arrangements, and choice of connections. The internal support ensures bags will not burst as high differential pressures build up during operation. Made with unique materials, each bag is constructed for strength and does not allow any pollutants or any other harmful particles to pass.
