biological aerated filter (baf) is a kind of water treatment process with biofilm process. it has the advantages of short residence time, small floor area and little excess sludge. it is widely used in short process sewage treatment plants, advanced sewage treatment, eutrophication and other fields.

qingquan, shenzhen, is the first enterprise to do biological aerated filter in china. the developed non clogged biological aerated filter completely solves a series of problems such as clogged filter head of conventional biological aerated filter, easily damaged aerator, easily lost filter material, uneven water distribution, unclean washing, etc. the technology has a number of invention patents, and has been approved and accepted by the ministry of science and technology of the people's republic of china.

1. the innovative water and air distribution system solves the problems of filter plugging, uneven water distribution, easy damage of aeration system and uneven aeration;

2. innovative low-intensity backwash technology, not only wash clean and short biological recovery time (at least 3 times shorter), but also wash interval up to 168 hours (48-168h);

3. reasonable pool structure, no filter material running in the backwashing process, and low-level washing for the impact of new microorganisms;

4. as a secondary treatment, it will greatly reduce the amount of sludge produced in the sewage treatment process.
