A simpler way to remove PFAS

 Highly contaminated, complex water doesn't always need a highly complicated treatment system.
Chromafora's PFAS flocculation technology removes up to 95% of PFAS using a straightforward process built on familiar water treatment equipment.

Built for difficult water

Landfill leachate and industrial wastewater often contain PFAS alongside organic matter, suspended solids, metals and other contaminants – conditions that can make conventional PFAS filtration both difficult and costly.

Flocculation offers a practical alternative: it binds PFAS into separable solids, and can be used either as the primary PFAS treatment method or as a pretreatment step ahead of a polishing technology such as SELPAXT, GAC or ion exchange.

How it works

Flocculation – Chromafora's PFAS flocculant and supporting treatment chemicals are added to the water, causing PFAS to bind into flocs.

Flotation – the suspended solids are separated from the treated water.

Dewatering – the PFAS-containing sludge is dewatered, reducing the volume requiring further handling.

Why flocculation?

Effective

Removes up to 95% of PFAS, depending on water characteristics and operating conditions.

Low complexity

No specialized PFAS treatment equipment required.

Reliable

A straightforward process that is simple to operate and maintain.

Versatile

Can also support pretreatment and removal of heavy metals and other pollutants.

Where it fits

Landfill leachate

One of the primary, most established applications for PFAS flocculation. 

Industrial process water

For water matrices where PFAS occurs together with other contaminants. 

Fire-suppression water  

Including complex waste streams from firefighting activities and training sites.

CUSTOMER CASE

Proven in full-scale operation

Chromafora's containerised flocculation system has treated more than 8,000 m³ of PFAS-contaminated leachate for the Danish EPA, consistently achieving over 95% PFAS4 removal at a legacy landfill site.
