Aurea®
Aurea® is the best-in-class technology for sustainable and cost-effective removal of micropollutants from (waste)water.
Aurea® synergically combines: biological activated carbon filtration followed by chemical oxidation. The biological process removes organic matter and a wide range of organic micropollutants, without activated carbon replacement. The chemical oxidation step, requiring minimal oxidant input, eliminates remaining recalcitrant pollutants. Aurea® ensures high removal efficiency for a wide spectrum of substances, minimizes energy consumption and CO2 emissions and leading to lower operational costs.
