Frequently Asked Questions
Landfill leachate contains a complex and variable mixture of organic contaminants including PFAS, VOCs, AOX, pesticides, and pharmaceutical residues that require effective treatment before discharge. Activated carbon adsorbs these persistent compounds reliably, making it a proven polishing step or primary treatment technology for achieving discharge compliance. Puragen’s GAC solutions are engineered for the broad contaminant profiles and variable leachate compositions typical of municipal and industrial landfill sites.
Puragen’s activated carbon solutions remove PFAS compounds and pharmaceutical residues, dissolved VOCs including the BTEX group and adsorbable organic halides (AOX), and organic pesticides and herbicides such as Atrazine, Chlorpyrifos, and DDT. These contaminants are commonly found in leachate from municipal, industrial, and mixed-waste landfill sites. The specific carbon grade selected is matched to your leachate’s contaminant profile to ensure effective removal and consistent discharge quality.
Landfill leachate treatment in the US is subject to federal and state environmental regulations governing leachate collection, treatment, and discharge to surface water or sewer systems. Discharge limits are typically established through site-specific permits and pre-treatment standards that set maximum allowable contaminant concentrations. Puragen’s solutions are designed to support compliance with discharge permit conditions, and our technical team can assist in identifying the appropriate carbon treatment approach for your site’s requirements.
Mobile filtration is well suited to landfill leachate applications where treatment volumes vary seasonally, where a permanent system is pending, or where a compliance deadline requires rapid deployment. Puragen’s AquaSorber mobile units can be on-site quickly and require minimal site preparation, making them practical for both short-term and extended treatment programs. Mobile filtration also allows operators to trial carbon treatment performance before committing to a fixed installation.
Spent GAC from landfill leachate treatment is classified based on the contaminants it has adsorbed and handled accordingly through Puragen’s integrated logistics network, with reactivation or licensed disposal arranged to match the material classification. Puragen manages the full chain of custody from carbon exchange through to final processing, removing the handling burden from site operators. Contact Puragen to discuss spent carbon handling arrangements for your specific leachate application.
