DOUBLE TREAT®compressed airinfluenteffluentAQUA FILTERAQUA -DAFAustephas a wide and exclusive know how in the Double Treat®technology application, integrated with special mixing and aeration systems in the biological oxidation basins.PROCESS DESCRIPTIONIn the Double Treat®process the secondary sedimentation is replaced by Dissolved AirFlotation (DAF) for a more efficient and reliable separation of the treated effluent from the biological sludge. The clarified effluent passes through a continuous self-cleaning sandfilterthat provides the final polishing step for the suspended solids removal, in order to guarantee a constant high quality effluent.Double Treat plants can operate at high biomass concentration, therefore they are very compact. Sludge thickening is obtained during clarification without further equipment and costs.Due to the robust aeration and sludge clarification system, Double Treat®plants are reliable and long-lasting without maintenance.
