Abstract: Environmental issues have become serious social concerns of a global scale. Among these issues, the impact of water pollution is getting more serious. As the steel industry commits itself to sustainable development, the importance of identifying alternative methods for wastewater treatment becomes more apparent. The removal of pollutants from wastewater is an important and integral part of any industrial process. “ACTIFLO” process which is a new and developing technology. It is an alternative method for conventional clarifiers due its retention time, size,chemical consumption comparatively very less than clarifiers, nearly 20 times less than in size. Actiflo has wide range of applications: advanced treatment of secondary effluent, CSO and storm water treatment, drinking water etc; The Actiflo has many benefits like small process footprint, suited for restricted spaces and low system head loss, flexibility, short start-up time, minimum equipment maintain etc; This process has found very effective in removal of TSS and Turbidity.

Keywords: Actiflo, wastewater, physico-chemical treatment, microsand, weighted flocculation, lamellar settling, compact treatment unit.
