Flotation is an important process in water technology for liquid- solid separation in industrial wastewater treatment. Electro- Flotation Treatment Technique (EFTT) can be used for many industrial wastewater. The objective of this work is to study the efficiency of electro- flotation (EF) technique compared with other ordinary classical methods. The water quality parameters resulted from using this treatment technique were confide with local environmental legislation. Pollutants removal efficiency was reached 57-85%. Parameters used in this study include: Hydrogen Ion Concentration (pH), Total Dissolved Solid (TDS), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), oil and grease, total phosphorus, salinity, conductivity and bacteria total count.
