Synergistic effects of bacterial consortium and thermal energy on treatment of sewage by waste stabilisation pond.

ABSTRACT: The low rates of biodegradation of organic pollutants in wastewater have been attributed to the daily fluctuation of temperatures, which affects microbial metabolism and activities in reactors.  This work aimed to develop a method to degrade sewage pollutants using a synergistic effect of bacterial consortium and thermal energy, while a grey concrete pond served as the control. The results demonstrated that the temperature profile of ICCP showed that all through the experiment, the temperature was above 25 °C, which is a suitable temperature for mesophilic bacterial growth. A properly-stabilised effluent was achieved by the ICCP with a low biodegradation index between 0.11 and 0.14.  The values of BOD (95%) and COD (74%) removal efficiencies were obtained at a 10-day retention time in ICCP
