EquaCel® is a unique Wastewater Pretreatment process that utilizes the Parkson EquaReact® process along with Dissolved Air Floatation (DAF) technology as a system offering to achieve both hydraulic flow equalization and high efficiency soluble BOD and ammonia removal for Industrial wastewater pre-treatment. This process provides owners and operators with a more compact, efficient and cost effective, single or two-stage DAF treatment system. A poured in place concrete, precast concrete, prefabricated steel, or stainless steel structure is utilized, in which one or more DAF cells are combined with the Parkson EquaReact in one common structure. This provides controlled, consistent Soluble BOD and Total BOD removal and if necessary, TKN and Ammonia-N removal.
