Sizing and oxygen generator for waste water treatment

homepage

Sizing a system for waste water treatment is relatively simple.  As a guide the anount of oxygen dissolved in to the water should equate with the COD (Chemical Oxidation Demand) of the water.  Therefore if the COD of the water is 100mg/l and the water flowrate is 10 cubic metres per hour,  the actual weight of COD will be 1000 grammes per hour. The size of oxygen generator required will be 6.7.22. The number of diffusers required can be determined from the gas flow rate for the diffusers in the ceramic diffuser section.
