N2 - DAF (Dissolved Air Flotation) is an effective method for removing low density particles from suspension such as oil-water emulsions. Using various air pressures in the pressure chamber with 44.7; 54.7; 64.7; 69.7; 74.7 and 79.7 psi, saturated air is pushed into flotation coloumn brought oil particles to creep up to the surface of oil-water solution. The content of oil in the solution is in the range of 250 - 1000 mg/l. To improve the capability of oil particles removing, aluminium and ferric sulphate are used as coagulants with 20 mg/l aluminium sulphate and 120 mg/l ferric sulphate. The work focuses on the influence of air saturated pressure DAF on the procentage of oil removal from wastewater using different coagulant. Ferric Sulphate is more effective than aluminium sulphate for reducing oil concentration in the wastewater. Oil removal of 96.74 % is reached for ferric sulphate whether using of aluminium sulphate reached 95.08 % of oil removal. Increasing of saturated air pressure caused the procentage of oil removal increased. The increasing of oil removal procentage is proportional with the increasing of oil concentration in the influent.
