ROTATING BIOLOGICAL CONTACTOR(RBC)
The rotating biological contactor or RBC is a biological treatment process used in the treatment of wastewater following primary treatment.
Attached growth process is associated with this
Attached growth process
Biological treatment technique in which micro organisms are attached to some inert medium, such as rock, slag, or specially designed ceramic or plastic materials
Advantages offered by rotating biological contactors:
Short contact periods are required because of the large active surface
Operating costs are low because little skill is required in plant operation
Short retention time
Low power requirements
Low sludge production and excellent process control
Applications
Municipal wastewater treatment
Food & Beverage wastewater treatment
Refinery & petrochemical wastewater treatment
Pulp & paper wastewater treatment
Sewage treatment
chemical analysis
COD , DO and Turbidity for the treated and untreated samples were analyzed in accordance with the standard methods for wastewater examination
