Proposing of an aerated water treatment plant for reducing water pollution problem in Losari Beach after reclamation

. Losari Beach is the most important site in Makassar. It lies at the west side of Makassar city. This place is\udknown as the place where people are relaxed and gathering with friends or family after working, and now it becomes the\udicon of Makassar city. As the biggest city in eastern Indonesia, Makassar grows very fast. We can find constructions for\udbuilding hospitals, shopping malls, bussines activities, and residences everywhere. The most important construction\udactivities that will effect Losari Beach is the reclamation to build the Center Point of Indonesia that takes an area of 157\udhectares and it is located at the west side of Losari Beach. In the last research presented in 9th International Conference\udon Marine Technology (October 2014) using surface-water modeling system (SMS) software showed that reclamation\udwill significantly increase concentrations of BOD and COD (?? 7 mg / L for BOD and 6.2 mg / L for COD). This\udcondition will cause Losari Beach becomes very polluted. A probable solution to overcome this problem is to clean the\udwastewater before introducing to the sea. This paper will describe the type of the wastewater treatment plant that can be\udused to solve the water pollution problem in Losari Beach
