This facility processes recyclable collected from over 250,000 households in Washington state. The 6.49-acre facility is currently permitted under the WA Industrial General Permit (ISGP) and triggered a level 3 corrective action in 2017 for total zinc. Clear Water conducted a pollutant source assessment and bench-scale treatability testing to determine the most effective chemical coagulant/flocculant and/or adsorption filtration. The final treatment system configuration was pretreatment with BHR-P50, flocculation, gravity settling and filtration. Clear Water was able to show efficacy and performance of a permanent active treatment system to treat contaminants of concern to below permit benchmarks. In late-2017, Clear Water installed a 150-GPM treatment train. Since the installation of the treatment system, this facility has met all applicable ISGP parameters.
