Industrialization is spreading rapidly and is necessary for the development of nation. On the other side, there is a threat to nature. Harmful emission in the air or water can damage the environment hence it is important to recover such toxic particulate matter from the exhaust gas. There are numerous ways to ensure that such pollutants are not released. Scrubbers, electrostatic precipitators, bag filters are some of the designs that retains particles and release clean air. Bag filters have been the choice for most of the industries these days. Bag filters have equally distributed 6 to 8 septa filters to avoid over expansion due to pressure. The filters are placed close to each other to ensure efficient filtration. The newer type of filters makes use of weaver of composite material to turn off the harm that may cause people. The static filter helps in efficient trapping of micro dust or minute particulate matter. This property also enhances good air permeability and long life of the bag filters. The filter bags needs to be intact and physically strong so that the wind pressure does not disrupt its structure. This can be achieved by fixing bonding jumper to the bag filter. They have self cleaning ability because it can blow the blowback air by itself to blow off the dust in the bag.
