ʻO ka wai kai electro-chlorination kahi hana e hoʻohana ai i ke au uila e hoʻololi i ke kai i loko o kahi disinfectant ikaika i kapa ʻia ʻo sodium hypochlorite.Hoʻohana mau ʻia kēia mea hoʻomaʻemaʻe i nā noi kai e mālama i ka wai kai ma mua o ke komo ʻana i loko o nā pahu ballast moku, nā ʻōnaehana hoʻomaha a me nā mea hana ʻē aʻe.I ka wā electro-chlorination, hoʻoheheʻe ʻia ka wai kai ma o kahi cell electrolytic i loaʻa nā electrodes i hana ʻia me ka titanium a i ʻole nā ​​​​mea hana ʻole.Ke hoʻohana ʻia kahi ʻano pololei i kēia mau electrodes, e hoʻohuli i ka paʻakai a me ka wai kai i ka sodium hypochlorite a me nā huahana ʻē aʻe.ʻO ka sodium hypochlorite kahi mea hoʻoheheʻe ikaika i ka pepehi ʻana i nā maʻi bacteria, nā maʻi maʻi a me nā mea ola ʻē aʻe e hoʻohaumia i ka ballast o ka moku a i ʻole nā ​​​​pūnaewele hoʻomaha.Hoʻohana ʻia e hoʻomaʻemaʻe i ka wai kai ma mua o ka hoʻokuʻu ʻia ʻana i ke kai.ʻOi aku ka maikaʻi o ka electro-chlorination i ka wai kai a ʻoi aku ka liʻiliʻi o ka mālama ʻana ma mua o nā lāʻau lapaʻau kuʻuna.ʻAʻole ia e hoʻopuka i nā huahana ʻino, e pale ana i ka pono o ka lawe ʻana a mālama i nā kemika pōʻino ma luna o ka moku.

ʻO ka holoʻokoʻa, he mea hana nui ka electro-chlorination o ke kai no ka mālama ʻana i nā ʻōnaehana kai i ka maʻemaʻe a me ka palekana a me ka pale ʻana i ke kaiapuni mai nā mea haumia ʻino.
