Day-Glo’s Radiant Color business recently engineered a wet air scrubber that, in six months, has eliminated wastewater generation and significantly reduced formaldehyde emissions during the manufacturing of its specialty pigments and resins. This is just one of the many ways that RPM is building a better world through its environmental, social and governance (ESG) initiatives.
Designed to eliminate harmful pollutants from process exhaust systems, this wet air scrubber technology moves air that is contaminated with formaldehyde through the filtration system using process water as a solvent. The formaldehyde is then captured and transported to the process tank, where hydrogen peroxide is used to convert the formaldehyde into water and carbon dioxide—which effectively dissolves the pollutant gas. Once the formaldehyde has been eliminated, the process water can then be reused in the wet air scrubber. Radiant Color now has a total of four wet air scrubbers in operation.
