This presentation describes the full scale installation of a wastewater treatment system at the Ocean Gold Seafood ("OCS") plant in Westport, Washington, USA. Local Government requires that fish processors remove total suspended solids (TSS), fats, oil and grease (FOGs) and colloidal materials almost completely in order to allow for efficient disinfection. Clean Water Technology, Inc. ("CWT") and OCS teams designed the system with an underground equalization tank, 1/8 inch rotating drum screens, flocculation– flotation ("GEM System") and chlorination–dechlorination. Hybrid centrifugal–dissolved air flocculation–flotation (the GEM System), is the key component of the wastewater treatment plant. TSS and FOGs are almost completely removed to less than 20 mg/l and 1 mg/l, respectively. This allowed for successful breakpoint chlorination–dechlorination and fecal coliform removal (99.995%). Novel ultrahigh molecular weight polyacrylamide flocculants used in the process enabled TSS and FOG removal even at high salinity.
