Waste is the residue resulting from an activity and production process, both at household, industry and mining. The purpose of this study was to determine the wastewater treatment process. This research method using the Waste Water Treatment Plant (WWTP) with a system of Dissolved Air Flotation (DAF). Waste processing results before processing, that wastewater treatment chemicals (coagulant and flocculant), suspended solids with a value of 10 348 ml / L, BOD 100 ml / L, and COD of 300 ml / L. So can reduce suspended solids 4.194 ml / L, BOD 80 ml / L and COD 160 ml / L, the value per cent reduction in suspended solids 85-95%, 50-70% reduction in BOD and COD reduction of 50-70%.
