Filter Bags are an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air. These bags are used for the clarification/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. Filter Bags are placed inside of bag filter housings for the purpose of purification by removing solids from wastewater. They are typically used in the treatment of industrial process water, wastewater, groundwater, and cooling water, along with many others.
