Enwere igwe na-eme ka ịcha ọcha dị iche iche dị maka ịchacha akwa nke nwere ike imepụta ihe na-acha ọcha dị ka sodium hypochlorite. Nke a bụ ụfọdụ nhọrọ: 1. Igwe ọkụ eletrik: Igwe a na-eji nnu, mmiri na ọkụ eletrik emepụta sodium hypochlorite. Usoro electrolysis na-ekewa nnu n'ime sodium na ions chloride, na-agwakọta gas chlorine na mmiri ka ọ ghọọ sodium hypochlorite. 2. Batch reactor: Ogbe reactor bụ akpa maka ịgwakọta sodium hydroxide, chlorine na mmiri iji mepụta sodium hypochlorite. A na-eme mmeghachi omume ahụ n'ime ụgbọ mmiri mmeghachi omume na usoro ngwakọta na-akpali akpali. 3. Reactor na-aga n'ihu: Onye na-arụ ọrụ na-aga n'ihu yiri nke batch reactor, mana ọ na-aga n'ihu ma na-emepụta usoro sodium hypochlorite mgbe niile. 4. Ultraviolet Disinfection Systems: Ụfọdụ igwe na-eji ultraviolet (UV) oriọna na-emepụta ịcha ọcha maka ákwà ịcha ọcha.
