Description
Summary:This project proposes a contact tank prior to the aeration tank in conventional wastewater treatment plant (WWTP) for energy recovery purpose. The main function of the contact tank is to provide a suitable environment for rapid uptake of organic substrates by activated sludge. A physical sorption process during a short time period following the sludge/effluent contact is called biosorption, which occurs at the interface of the sludge/effluent and is defined by the amount of COD retained by biomass.
