The feed process wastewater enters the Redux^TM DAF treatment system via an influent equalization tank (EQ) which helps stabilize the feed water characteristics such as flow rate, pH, and contaminant loading. This standardizes the treatment process and effluent quality. The feed water is pH adjusted (if needed), and precipitating and coagulating chemicals are added upstream of the Cornell DAF pump to provide optimal separation characteristics for the wastewater. Chemical requirements and dosing are determined in Milieu-Nomics’ development laboratory at The DuPage Technology Center, or by the clients’ chemical supplier. Inline mixing ensures complete reaction of the chemicals with the wastewater. The chemically treated stream then travels through the Cornell DAF pump which efficiently introduces and dissolves air into the wastewater and boosts the pressure of the combined fluids.

The wastewater is pumped under pressure to the unique Redux^TM clarifier, enroute a flocculant may be added and mixed with the pressurized stream. Just before entering the clarifier the stream is released to atmospheric pressure, and the dissolved air in the wastewater comes out of solution as extremely fine, stable bubbles, and quickly begin to rise to the top of the liquid in the clarifier, carrying the solids and other contaminants in the wastewater that attach to the bubbles with them. The Redux^TM clarifier’s unique hydraulic design ensures uniform flow and distribution through the clarifier, as well as providing extremely effective separation of the float from the liquid phase. This increased effectiveness allows higher flows per unit area of clarifier. The highly clarified water flows out from the lower side outlet of the clarifier to a clean water holding tank for subsequent transfer, treatment and reuse, or discharge. The floating solids are compacted as they rise up the clarifier cone, and are discharged through the angled exit pipe to a sludge holding tank for further transfer and treatment. If VOCs are a concern, the exhaust gases can be captured through the vertical exit pipe and routed to a scrubber or other treatment system for control. The conical clarifier is designed and constructed to eliminate all fugitive emissions. The solids compaction in the clarifier results in higher sludge solids, and lower water content, which can make further treatment less costly. The clarification and float separation process is continuous and involves no moving parts, ensuring consistent and high quality effluent results, with minimal maintenance and process upsets. Combined technology provides the best operating DAF system in the market today.
