Abstract Effluent treatment A process for treating effluent wherein an oxidising agent in the effluent is decomposed on contact with a catalyst bed. The oxidising agent can be a pollutant present in the effluent, for example hypochlorite in the effluent from chlorine- producing brine electrolysis cells or from the scrubbing of chlorine gas. In an alternative the effluent may contain oxidisable pollutants and the oxidising agent is purposefully added thereto. Passage over the catalyst bed catalyses the decomposition of the oxidising agent and oxidisable pollutants. The catalyst bed comprises an intimate mixture of an oxide of Group III, nickel oxide and, optionally, cobalt oxide, supported on pieces of a non-porous substantially inert material.
