Abstract:
1. A single-pass flow-through mixing apparatus for incorporating a dry treatment product into a liquid waste, said apparatus comprising: a pump for directing a liquid waste from a storage pit/tank; a mixer receiving said liquid waste from said pump, said mixer comprising a jet nozzle, a venturi tube and a high-shear assembly for incorporating said dry treatment product into said liquid waste; a valve downstream of said mixer for either recirculating said liquid waste back to said storage pit/tank via a recirculation conduit, or directing said liquid waste to a discharge conduit; wherein said recirculation conduit defines a calibration loop for determining an appropriate treatment regimen including an amount of dry treatment product necessary to treat said liquid waste based on the characteristics of the liquid waste; said recirculation conduit also permitting homogenization of said pit/tank contents prior to addition of said dry treatment product; and wherein dry treatment product introduced at the mixer is subjected high shear forces, thereby incorporating the dry treatment product into the liquid waste with increased dispersion and reduced agglomeration.
