After being fed with low-voltage direct current, N₃EO series products will generate a large number of hydroxyl radicals, active oxygen and hydrogen peroxide, which can completely convert organic pollutants, sulphur compounds and ammonia nitrogen into carbon dioxide, sulphate and other substances. This world’s leading ‘cold combustion’ technology can be widely used in the degradation of wastewater in the pharmaceutical, chemical, brewery, municipal, tobacco, new energy and other industries without adding any chemicals, with no sludge and no secondary pollution, is entirely safe and efficient.
