Abstract
A catalyst for use in abatement of organic compounds, including noxious compounds in water, wherein the water in a first step is enriched with ozone/oxygen. The enriched water is then passed through a catalyst, consisting of activated carbon as carrier for metal oxides including iron oxide, cobalt oxide, nickel oxides, manganese oxide. Furthermore, the catalyst can contain one or more of the noble metals, preferably platinum or palladium. By the catalyst, undesired intermediate products from the ozone treatment are avoided. The catalyst is employed in a water treating plant and in a process for treatment of water.
Claims10
A continuous process for abatement of organic compounds in ground water, comprising the steps of:
- enriching the ground water at usual ground water temperature with ozone and/or oxygen to obtain enriched water;
- and
- passing the enriched water to a catalyst comprising activated carbon as carrier material and at least one metal oxide supported on the activated carbon and selected from the group consisting of the oxides of iron, cobalt, nickel and manganese to obtain purified ground water.
