In recent environmental regulations have been stringent and requiring high quality of treated wastewater and also there is an increasing trend to require more efficient method wastewater from industries. We have developed a new treatment method called an advanced oxidation process coupled coagulation, flocculation, and biological treatment based on laboratory experiments to treat wastewater. The aim of research work was select optimal conditions of laboratory experiment. In this experiment NOXXALL is liquefying ozone, hydrated lime, poly aluminium chloride, polyelectrolyte, and intermittent cycle extended aeration system were used an oxidizing agent, coagulants, flocculent, and an aerobic treatment respectively. In this method reduction of suspended solids, total dissolved solids, chlorides, sulphate, biological oxygen demand, chemical oxygen demand, oil and grease, phenols, and arsenic were 97,54,79,78,98,96,85,66,53% respectively. Zebra fish used in bio assay test, and were survived 100% in final treated wastewater.
