BIOMODULE is a variant of the activated sludge biological process which allows continuous inflow of raw wastewater and intermittently discharged influent.

​

Provides flow equalization, biological oxidation and sedimentation with decanting of supernatant in a single tank.

 

Process can be operated on any cycle duration based on the required degree of treatment. Each cycle consist of aeration, sedimentation and decantation phases. The aeration phase can be operated on an oxic/anoxic mode for the purpose of nitrification/denitrification and biological phosphorus removal. Oxygen is provided to the mixed liquor by the blowers and aeration system. The blowers are either positive displacement or centrifugal type. The most common aeration system utilizes coarse bubble diffusers. Jet aeration and fine bubble system have been used effectively as well. A master control center completely automates the process.
