DEXSORB® Treatment Of Landfill Leachate In Pennsylvania

Landfill leachate ranks among the most complex industrial wastewater streams, often containing extreme total fluorinated organic loadings exceeding 120,000 ppt along with high background dissolved solids. While membrane bioreactors effectively stabilize heavy organic compounds and nutrients during primary treatment, persistent chemical contaminants pass through intact, necessitating a high-capacity polishing step before discharge. Deploying a multi-vessel packed-bed filtration system directly downstream of a membrane bioreactor provides continuous, single-step contaminant removal. Across 102 days of pilot operation treating over 150,000 gallons of post-MBR effluent, this filtration configuration delivered total removal of key target compounds like PFOS, PFHxS, and PFNA without experiencing biofouling, clogging, or backwashing requirements.
