Abstract
This invention relates to the removal of hypochlorite groups from aqueous effluent solutions, so as to permit the disposal of the effluent by deep well injection. More particularly this invention relates to the catalytic decomposition of such hypochlorite groups from scrubbing water effluent used to remove chlorine from a gaseous effluent, wherein a solid catalyst is dissolved, recycled and reprecipitated in situ.
