Water Treatment
Granular, powder, impregnated, and catalytic grades for drinking water, municipal systems, and wastewater purification.
Black Opal supplies activated carbon for drinking water, industrial process water, municipal systems, groundwater remediation, and wastewater polishing.

POU water filters
Water filters, cartridges, and carbon blocks are among the most widely used water-filtration technologies. Black Opal emphasizes balanced adsorption and pore structure, low ash, high strength, and consistent particle-size distribution.
Municipal and industrial water
Municipal and industrial systems use activated carbon for taste, odor, and color removal, plus adsorption of VOCs, pesticides, disinfectant by-products, chlorinated hydrocarbons, and inhibitory compounds.
Wastewater treatment
Granular carbon supports fixed-bed removal of dissolved non-biodegradable organics, while powder carbon supports sludge-contact treatment programs to improve stability and settling.
