Emerging Technologies Treatment updated 2012 March 2013 Technology Summary BioActiflo® Process (continued) Comparison to Established Technologies: Compared to conventional biological treatment systems, the BioActiflo® provides treatment to all flows entering a plant. It also has a relatively small footprint due to its short hydraulic retention time and high surface loading rates. While the coagulation and flocculation tanks ahead of the Actiflo unit add to the system footprint, this is still a much smaller footprint option than a conventional secondary clarifier (Fitzpatrick et al, 2012). The clarification part of the BioActiflo® process also allows dual use operations for wet weather peak flow treatment and dry weather primary or tertiary treatment if desired. Compared to primary or chemically enhanced primary treatment processes, the BioActiflo® process is not as limited by existing clarifier capacity. By combining proven treatment technologies such as high-rate contact-stabilization and ballasted sedimentation, site constraints can be ameliorated at significant capital and operating cost savings (Katehis et. al, 2011). It should be noted that BioActiflo® testing to date has been based on site specific conditions. As such, more data is needed to determine if BioActiFlo could be utilized in lieu of conventional treatment. Available Cost Information: Approximate Capital Cost: Not disclosed by vendor.
