Our technologies

Advanced water treatment powered by selective chemistry

 

Chromafora offers technologies that remove PFAS and metals from complex water streams – and recover valuable resources in the process.

Every solution is built around one idea: selectivity. By targeting exactly what needs to be removed, we treat even the most demanding water streams efficiently, with less waste and lower long-term cost.

Three technologies. Different challenges.
One selective approach.

SELPAXT. 
Advanced PFAS removal

For the most demanding PFAS challenges – including long-, short- and ultra-short-chain compounds – SELPAXT combines proprietary chemistry with ultrafiltration, concentrating PFAS into a residual stream as small as 0.1% of the treated volume.

PFAS Flocculation.
A simpler way to remove PFAS

For highly contaminated, complex water such as landfill leachate, flocculation offers a practical, lower-cost route to PFAS removal – up to 95%, using equipment your team already knows how to run.

SELMEXT. 
Selective metal extraction

SELMEXT selectively separates metals from water and hydrometallurgical process streams – removing what's unwanted, recovering what has value. Current development spans gold, uranium, scandium and mercury.

We can also offer...

Not every water stream needs a purpose-built selective technology. For simpler polishing needs – or where a conventional method is genuinely the right fit – we also provide granular activated carbon (GAC) and ion exchange (IX) systems, either standalone or as a polishing step after SELPAXT or flocculation.

Granular Activated Carbon (GAC)

A familiar, well-proven adsorption technology for long-chain PFAS – well suited as a polishing step after a primary PFAS-selective treatment stage.

Ion Exchange
Resins

Higher-selectivity adsorption media that can improve removal of certain short-chain PFAS – offered standalone or integrated into a broader treatment train.

EXPLORE IX

Different challenges. One selective approach.

 

PFAS and metals behave differently in water. That's why our technologies are designed around the specific contaminant, water matrix and treatment objective – combining proprietary chemistry with established separation processes to remove what matters while reducing unnecessary waste.

Technology

PFAS chain-length coverage

Residual waste

Sensitivity in complex leachate

Best fit

SELPAXT™ (SAMF)

Long, short & ultra-short – up to 99.7% removal demonstrated

Very low – as little as ~0.1% of treated volume

Low sensitivity to TOC and pH swings

High-strength, complex leachate; demanding or tightening discharge limits

PFAS Flocculation

Long- and short-chain – up to 95% removal

Moderate – dewatered sludge for disposal

Can be used to pre-treat high-DOC water

Cost-sensitive sites; pretreatment ahead of a polishing step

Reverse Osmosis

Broad-spectrum, high overall removal

High – 15–30% concentrated reject stream

Prone to fouling from salts, metals and organics

Sites with an established plan for concentrate destruction

Ion Exchange Resins

Long-chain; improved removal of some short-chain PFAS

Low media volume, but regeneration can generate brine/secondary waste

Fouls with high chloride and organic loading

Polishing step, or simpler matrices with lower fouling risk

Granular Activated Carbon

Long-chain; limited affinity for short- and ultra-short-chain PFAS

Spent carbon requiring replacement/incineration

Reduced adsorption efficiency in high-DOC matrices

Polishing step, or simpler streams dominated by long-chain PFAS
