Bag Filters are used for the filtration of fluids that have a relatively small loading of particles to be removed. The particle suspension passes through and the particles settle in the bag. The Filtration occurs from inside to outside with a water pressure of more than 2kg/cm2. Therefore, these bag filters are normally used with a supporting vessel called bag filter housing. In situations where support cannot be used, the pressure drop across the filter needs to be lower.
It is normally made from needle-punched nonwovens and acts as depth filters. Also, the bag is stitched from the edges.
A bag filter is currently used in many industries where filtration is less critical and the bags can be easily disposed of. The main purpose of a Bag Filter is to filter out the impurities such as sand, dust, etc from water.
A Bag filter filters all the physical impurities like sand, dust, mud, and silt from the water, and the color white. The Bags can be removed by hand, with all solids contained for disposal.
bag Filter has a low price and is available in many materials and configurations for multiple applications and compatibility.
