OXIDATION ORGANIC SLUDGE
I.T.A.R. builds biological treatment with activated sludge, continuous and sequential (sequential bach reactor).
The choice between the two systems depends on the type of discharge and the processing carried out.
In practice, in the bath of purification takes place in a forced way what happens in nature,
ie the biological degradation of the waste by selected microorganisms that give rise to biological sludge.
The microorganisms that form the biological sludge are selected from oxygen which is forcibly injected into the oxidation tank.
These organisms feed on pollution.
Not surprisingly, the amount of pollution is measured in COD (chemical oxygen demand)
and BOD (Biochemical Oxygen Demand), which is the amount of oxygen-consuming microorganisms to degrade the pollutants.
The air in the oxidation tank is distributed evenly by means of a series of pans placed on the bottom of the tank,
or by means of turbines and submersible aerators.
