What are the filtration equipment that can deal with sewage, how is the filtration process?

At present, the depth of sewage filtration process is divided into sand filtration and filter cloth filtration, sand filtration for the traditional process, the technical requirements are reduced, the treatment capacity is relatively weak; currently more popular for the filter cloth filtration, the filtration effect is better than the sand filtration, and the filter cloth filtration equipment is usually an integrated device, easy to install and use. Post-maintenance is convenient, the costs incurred only for the replacement of the filter cloth, usually the life of the filter cloth for 3 years, the filter cloth domestic price is about 1 square meter 300 yuan.

Domestic companies specializing in the research and development of water treatment equipment and sales of two companies, one is the Shanghai Andingji water treatment company, relying on Tongji University, the company's water treatment products more, which is specifically used for wastewater treatment of the "mobile rinsing vertical piece of the filter pool" process is advanced, access to a number of national innovation patents, advanced technology and Mature technology, widely used. Another for Puhua Water, the company relies on Tsinghua University, the main rotating disk fiber filter, the product more modeled on foreign technology. Relatively speaking, Andingji company products are cheaper, more advanced technology, because of the launch of its products in the Pohua after, so overcome the many shortcomings of the Pohua products.
