The Blue PRO^® reactive filtration process achieves the lowest total phosphorus levels in municipal wastewater, reduces metals and other contaminants cost-effectively, and can lower total mercury to less than 1 ppb. This patented process achieves these results by optimizing adsorption of contaminants onto hydrous ferric oxide (HFO) coated sand, a highly effective adsorptive media. Best of all, the media is continuously regenerated within the filter bed, so there is never a need for exchange or disposal of spent media. Waste contaminants are removed from the continuously backwashing system, and the iron is recycled to benefit from its excess adsorptive capacity.

Nearly every wastewater conference quietly buzzes with conversation on removal of emerging contaminants such as endocrine disruptors, pharmaceuticals, and other complex organics from wastewater. Pharmaceuticals and personal care products (PPCPs), sometimes known as endocrine disrupting compounds (EDCs), are slowly changing the biology of aquatic life around the world. The impact to drinking water quality and human health is a growing concern.
