The working principle of liquid bag filtration is pressure filtration. The whole bag filter system consists of three parts: filter container, supporting basket and filter bag. Filtering of the liquid from the top into the container, from inside to outside, the bag to distributed evenly over the entire surface of the filter, filter out particles trapped inside the bag, no leak, human nature is changed and convenient design, the overall structure, operating efficiency, large capacity, long service life, is liquid filtration industry energy saving products, applies to any fine particles or suspension of coarse filter, filter, fine filter.

The design of the filtration system should take into account the process conditions (temperature, pressure, accuracy, medium characteristics, viscosity, flow rate, impurity type, content and size, etc.) and operation conditions (placement space, opening form, planned bag changing period, etc.) and the cost budget.
