Abstract
Waste water containing biodegradable matter is fed to a rotating biological contactor (RBC) (15) from an inlet tank (10) and is discharged from the RBC-containing chamber into a humus tank (21). The RBC is divided into separated upstream (15A) and downstream (15B) sections, the chamber (17) containing the downstream section being fed with water to be processed at a controlled rate from the chamber (16) containing the upstream section. A balancing chamber, for isolating the downstream section of the RBC from variations in flow of waste water to the inlet tank (10), includes the upstream section (15A, 16) of the RBC which can act sacrificially in respect of toxic incursions in the waste water.
Claims9
In a method of processing wastewater containing biodegradable matter which involves feeding a chamber containing a rotating biological contactor (RBC) with wastewater from an inlet tank and discharging from the RBC-containing chamber into a humus tank, the RBC being divided into separated upstream and downstream sections, the chamber containing the downstream section being fed with water to be processed at a controlled rate from the chamber containing the upstream section and a balancing chamber is provided for isolating the downstream section of the RBC from variations in flow of wastewater to the inlet tank, the improvement which comprises the upstream section of the RBC forming part of the balancing chamber.
