Shanxi Runtong Environmental Engineering Limited was founded in 2005 in Shanxi waste water filters, is a professional sewage treatment, waste gas treatment, dust handling and other types of environmental projects and research and design of high-tech enterprises. Chinese Ancient filtering technology already applied in production, 200 BC has been made of plant fiber paper. 105 AD Cai Lun improved the paper making process. He will plant fiber pulp papermaking process in dense fine finishes on bamboo. Water filtered through bamboo slits, a thin layer of wet bamboo pulp left in the face, dry Serve paper. The first filter mostly gravity filtration, then pressurized filtration improves filtration rate, which in turn appeared vacuum filtration. Early 20th century invention of vacuum drum filters to achieve a continuous filtration operation. Thereafter Shanxi sewage filter, various types of continuous filter has emerged. Filter intermittent operation (such as plate and frame filter press, etc.) because it can be developed to automate operations, filtration area is growing. In order to obtain a low moisture content of chemical residues in Shanxi filter, mechanical filter press has been developed. Sewage Filter Applications sewage treatment filters using the occasion to have a drainage system metallurgical industry --- casting and rolling water systems, blast furnace water system, turbidity, net loop water recycling systems and water systems; steam turbine power plant cooling water systems industry ; boiler wet cooling water systems; large air compressor, a large oxygen machine, large air-conditioning cooling water system; Turbine sea, lake, river DC cooling filtration system. In agricultural drip irrigation system has also been widely used.
