Abstract

A system for removing ammonia from wastewater includes a series of interconnected reactor tubes that each comprise an outer cathode and an inner cathode that is centrally positioned within the outer cathode to form a spacing of between 3 mm and 10 mm through which wastewater may flow. At least one of the reactor tubes includes an inner cathode having a MMO coating. Hypochlorite or another chlorine based element can be supplied to wastewater prior to passing through the reactor tubes. The presence of the hypochlorite within the wastewater and the generation of chlorine by the MMO coated cathode result in an increased level of hypochlorite being present in the wastewater which speeds the breakdown of ammonia. A portion of the wastewater processed through the reactor tubes can be diverted through a feedback path to the input to the reactor tubes to increase the amount of hypochlorite present in the unprocessed wastewater.
