WT - New Type Aerated Biological Filter Process Package
The Biological Aerated Filter (BAF) technology is developed based on fully absorbing the advantages of foreign BAFs. BAF has the dual functions of biochemical treatment and filtration, which can simultaneously remove organic matter, nitrogen, phosphorus, and suspended solids from wastewater. The principle of wastewater treatment by the BAF is the oxidation and decomposition of microorganisms in the biofilm attached to the filter material within the reactor, the adsorption and retention effects of the filter material and biofilm, the food chain predation effect formed along the direction of water flow, and the denitrification effect in the microenvironment of the biofilm. As filtration progresses, the newly generated biomass on the surface of the filter material increases, and the retained SS continues to rise. In the initial stage, the head loss in the filter increases slowly. When the accumulation of solid substances reaches a certain level, causing the head loss to reach its limit, the head loss may lead to the penetration of SS. At this point, backwashing of the filter is required to remove the excess biofilm and SS within the filter bed, restoring its treatment capacity.
