Catalytic Diamond® Technology

Catalytic Diamond® is a novel state-of-the-art technology capable of removing persistent contaminants from groundwater and industrial waste streams. The system is based on an effective combination of molecular adsorption filtration and catalyst induced advanced radical oxidation.

Adsorption

The first step of molecular adsorption ensures the removal of specifically charged molecules and suspended organic compounds. The water is fed into a column packed with ceramic material via a distribution plate. The ceramic adsorption material has an open uniform structure and is chemically charged to enable the binding of specific target molecules. In the Catalytic Diamond® system molecular adsorption serves as a highly efficient pre-filtration step to provide optimal conditions for an efficient oxidation of the most persistent contaminants in the next stage.

Catalyst induced advanced oxidation

After the adsorption step, catalyst induced advanced oxidation will ensure the breakdown of contaminants into their basic elements. The oxidants hydrogen peroxide and in-situ produced doubly ionized oxygen are efficiently mixed with the water in a patented mixing chamber. The resulting mixture is injected into the oxidation column, which contains an immobilized chemical catalyst that will accelerate the conversion of the hydrogen peroxide into reactive radical species. The type of catalyst and radical species produced is selected based on the chemical nature of the contaminant. The produced radicals have large oxidation strength and will ensure decomposition of the most recalcitrant contaminants at a high energy-efficiency.
