Treating wastewater including wet weather flows, phosphorus removal and water re-use
Shortly after the development of the ACTIFLO® process for drinking water treatment in the early 1990's, investigations into the use of the process for wastewater treatment applications began.With its exceptional solids removal capabilities, the ACTIFLO® process can be utilized in any wastewater application that needs solids separation to include treating wet weather flows, phosphorus removal and water re-use to name a few.The ACTIFLO® process utilizes microsand as a seed for floc formation which later acts as a ballast or weight. The resulting sand ballasted floc, display unique settling characteristics, which allow for clarifier designs with high overflow rates and short retention times. These designs result in system footprints that are between 5 and 20 times smaller than conventional clarification systems of similar capacity.
With over 30 municipal wastewater treatment installations in the United States alone (as of August 2010) the ACTIFLO® process can be found treating wet weather flows at wastewater treatment plants or at satellite facilities, polishing wastewater flows to low phosphorus levels (< 0.10 mg/l) and reducing total suspended solids for water reuse production.
