Abstract

The paper presents comparison among the most frequently used waste water systems in developing countries. Various physico-chemical and biological techniques have been used for the treatment of domestic wastewater. The wastewater is conventionally treated either by suspended growth system, by attached growth system or combined suspended and attached growth system. The system studied were oxidation pond, activated sludge, upflow anaerobic sludge blanket, trickling filter and constructed wetland. All the above systems were designed and analysed based upon the various factors such as BOD removal efficiency, land required, power required, HRT, quantity of sludge to be handled, initial, operational & maintenance cost. The main summary table for quantitative analysis is prepared based on per capita values. It also includes the advantages and disadvantages of the treatment processes.
