Abstract

The present invention relates to a process for removal of ammonium from an ammonium-containing aqueous solution obtained by regenerating an ammonium-loaded ion exchange material (1) with an eluant liquid (2) comprising a chloride-containing salt, said process comprising the step of feeding said ammonium-containing aqueous solution or an ammonia-containing condensate obtained by stripping said ammonium-containing aqueous solution and removing ammonia from the stripping gas by condensation, and a separate aqueous solution of an alkali metal hypochlorite into a reactor (4) for converting the ammonium/ammonia to nitrogen gas (7) and for producing an essentially ammonium-free effluent stream (8), a portion (10) of said effluent stream (8) from the reactor being returned as the eluant liquid (2) to the regeneration of the ammonium-loaded ion exchange material (1).
