Application of GA and mathematical models in long sea outfall designing and concentration predictions

Abstract

Long sea out-fall is an acceptable method of domestic wastewater disposal, provided that the design is done properly, and it is constructed robustly and according to the design. The dispersion of the sewage after discharging to the sea has come under increased scrutiny in recent years, due to the sea and seashore pollution. In a properly designed and constructed long sea out-fall, the waste is discharged at a point in sea, away from any environmentally sensitive areas such as coral reefs, and far enough from the beach so that the quality of water reaching the beach conforms with stipulated standards. In this paper the development and applications of SOS (Sea Outfall System), a model developed at University of Moratuwa, will be demonstrated. SOS can be used in sea outfall designing, data analyzing and concentration predicting. The system is developed using OA optimizations and mathematical models.
