A Study on the Foam Wastewater Treatment and Foam Collection by Inhalation Force at the Outlet of Power Plants

발전소 방류구의 흡입력을 이용한 거품수거 및 거품액 처리 연구

Power Plant is requested, by environmental bodies and fisherman, to correct the pollution of coastal area due to the outflow of foam from the outlet of the power plants. Foam wastewater cause a lot of environmental problems, expecially in aesthetic points of view. Therefore, It is needed to be collect from the stream into nearby ocean, and the collected foams should be treated before being discharged into nearby ocean. The most effective and feasible treatment method researched for the effective treatment of foam wastewater generated at the power plants. The result of the test is confirmed with collecting Foam wastewater by inhalation force. The treatment pilot ($3m^3/hr$) collected wastewater was operated by Biological degradation method(Aerobic/anaerobic Processes) for approximately two months. It was removed SS, COD, nutrient(T-P, T-N), etc. The System is expected successfully by Minimizing the operating costs such as electricity, repair expenses, chemicals and supplies expenses.
