Treatment HCHO (5ppm) in water by using carbon filter, RO and Anion resin?

[nvthien14]

Hi everyone !
Our demineralized water system (DWS) has inlet water contain 5ppm HCHO. Our process include: Carbon filter => RO => Cation resin => Anion resin => Mixbed. Whether our DWS can treat HCHO (5ppm) ?
Is there any other solution to treat HCHO in water?

Thanks very much !

Sounds like you got it. What is the source? Can you limit it before it gets into the water? If your source is airborne a simple carbon air filter is a potential solution. We have used formaldehyde in manufacturing pharm products for years, removing it from air has been fairly simple. Water removal is typically done through ion exchange.
