BFA Biological Aerated Filter

BFA Biological Aerated Filter

Working Principle of BFA Biological Aerated Filter:
The BFA Biological Aerated Filter is used in aeration, filtration, interception and backwash with the contact oxidation process.
The biological film formed on the medium surface when wastewater flew into tank. At the same time, air flew into tank from aerating pipe. The wastewater can be cleaned by organics degradation under the metabolism of microorganism.
Solid substance and biological sludge can be intercepted by filtrate medium.
The backwashing starts when pressure loss over a set value.

Features of BFA Biological Aerated Filter:
(1) Small size and low cost.
(2) High water quality of effluent. ( SS≤10mg/l)
(3) High efficiency of oxygen utilization and low aeration rate
(4) Strong capability of resisting sudden load change and low temperature tolerance.
(5) Easy to form biological film

Applications of BFA Biological Aerated Filter :
(1) Middle water reuse in two-stage aeration
(2) Wastewater treatment in food and paper making industries.
