Flocculation Technology

Enhanced flocculation technology for removing PFAS is positioned as a simpler option for sites where traditional PFAS treatment can be too expensive or difficult to operate. The process is designed to deliver reliable treatment performance without specialized equipment.

The process is described for highly contaminated wastewaters such as landfill leachate, industrial process water, foam fractionation residuals, reverse osmosis reject and complex fire suppression system matrices. This makes it relevant for sites dealing with dirty, variable influent.

Enhanced flocculation technology for removing PFAS can be used as a pretreatment step before downstream PFAS removal. It can also support removal of heavy metals and other pollutants, helping teams address more than one water quality challenge within the same treatment strategy.

The treatment approach uses flocculation, solids separation and dewatering to bind PFAS to the treatment solution and remove suspended solids. Its simplicity supports easier operation and maintenance for waste management teams.

Onterris supports the full delivery path from laboratory testing and pilot evaluation through system build and ongoing service. This helps tailor treatment design to site-specific water quality, emissions requirements and operational needs.

The source materials describe experience using flocculation to remove PFAS at waste management sites, including landfill-focused applications and projects across Scandinavia. That background supports practical implementation in real operating environments.
