The company’s portfolio includes unique, patented water treatment technologies – SELPAXT and SELMEXT – based on proprietary chemistry. Chromafora’s PFAS removal technologies eliminate ultra-short-, short-, and long-chain PFAS from water streams, while its metal extraction technologies target the removal of heavy metals and contribute to the conservation of critical raw materials by enabling the recovery and recycling of valuable metals from waste. ## SELPAXT removes up to 99.7% of PFAS from water SELPAXT is an advanced water treatment technology designed to effectively concentrate and remove PFAS contamination from various water streams, including landfill leachates, industrial process water, firefighting training grounds water, and more. **[Read more on selpaxt.com](https://selpaxt.com/technology)** SELPAXT has demonstrated much higher reduction rates on more PFAS variants than other PFAS removal technologies on the market, capturing up to 99.7% of PFAS chains, both long and, otherwise hard to capture, short-chain PFAS. Compared with other, conventional methods such as activated carbon or ion exchange, The SELPAXT method is also more cost-effective and generates minimal waste; only 0.1% of the treated water volume.

This process, known as flocculation, removes up to 95% of PFAS. It can also be used to pre-treat leachate before PFAS removal, as well as to remove heavy metals and other contaminants. **Proven in real-world applications** Our team has extensive experience with PFAS flocculation. It is a proven technique that we have used to remove PFAS at landfills and other waste facilities across Scandinavia. **Benefits of PFAS flocculation** **Effective:** Removes up to 95% of PFAS **Low cost:** No specialized equipment required **Reliable:** Simple to operate and maintain [Contact an expert](https://chromafora.com/contact-us#contact-form) ## SELMEXT – Leading technology for removing heavy metals and extracting value metals from wastewater​. **SELECTIVE HEAVY METALS REMOVAL** The patented SELMEXT technology de-toxifies wastewater streams and reduce the waste masses through selectivity by selective separation/removal of toxic heavy metals from wastewater and effluents. Focus on treatment of landfill leachate and wastewater/effluents from mines and other industries. **SELECTIVE VALUE METALS EXTRACTION** The SELMEXT extraction technology recovers valuable materials and enables re-circulation by extraction of rare-earth elements and other value metals for recycling and re-usage from wastewater and effluents. Applications can be found in mining, industrial wastewater and landfill leachate.
