ʻO ka ʻenehana hoʻomaʻamaʻa neutralization o ka wai holoi wai ʻakika kahi hana koʻikoʻi i ka wehe ʻana i nā mea ʻakika mai ka wai ʻino. Hoʻopau nui ia i nā mea waikawa i loko o nā mea kūʻokoʻa ma o nā hopena kemika, a laila e hōʻemi i ko lākou pōʻino i ke kaiapuni.

1. ʻO ke kumu hoʻohālikelike: He hopena kemika ma waena o ka waikawa a me ka alkali, ka paʻakai a me ka wai. ʻO ka wai ʻawaʻawa holoi maʻamau he mau ʻakika ikaika e like me ka sulfuric acid a me ka waikawa hydrochloric. I ka wā o ka mālama ʻana, pono e hoʻohui ʻia kahi nui kūpono o nā mea alkaline (e like me ka sodium hydroxide, calcium hydroxide, a i ʻole lime) e hoʻopau i kēia mau mea ʻawaʻawa. Ma hope o ka hopena, e hoʻoponopono ʻia ka pH waiwai o ka wai ʻino i kahi pae palekana (maʻamau 6.5-8.5).

2. Ke koho 'ana i nā mea ho'oku'u: 'O ka sodium hydroxide (caustic soda), calcium hydroxide (lime), a pēlā aku. Hoʻopili wikiwiki ka sodium hydroxide, akā pono ka hana akahele e pale aku i ka huʻa nui a me ka paʻi; Hoʻopili mālie ka calcium hydroxide, akā hiki ke hana i ka wai ma hope o ka mālama ʻana, kahi kūpono no ka wehe ʻana ma hope.

3. Mana o ka neutralization kaʻina hana: I loko o ka neutralization kaʻina hana, pono e nānā i ka pH waiwai o ka wastewater i ka manawa maoli e hōʻoiaʻiʻo i ka kūpono acid-base ratio. ʻO ka hoʻohana ʻana i kahi ʻōnaehana hoʻokele automated hiki ke hoʻokō i ka dosing pololei a pale i nā kūlana o ka nui a i ʻole ka hemahema. Eia kekahi, e hoʻokuʻu ʻia ka wela i ka wā o ke kaʻina hana, a pono e noʻonoʻo ʻia nā moku pane kūpono e pale i ka wela nui.

4. Lapaʻau ʻana ma hope: Ma hope o ka hoʻokaʻawale ʻana, hiki ke loaʻa i ka wai ʻino nā mea paʻa i hoʻopaʻa ʻia a me nā ion metala kaumaha. I kēia manawa, pono e hui pū ʻia nā ʻano lapaʻau ʻē aʻe e like me ka sedimentation a me ka kānana e hoʻoneʻe hou i nā koena haumia a hōʻoia i ka hoʻokō ʻana o ka maikaʻi o ka effluent i nā kūlana kaiapuni.

Ma o ka ʻenehana lapaʻau neutralization kūpono, hiki ke mālama pono ʻia ka wai holoi wai wai, e hōʻemi ana i kona hopena i ke kaiapuni a me ka hoʻoikaika ʻana i ka hoʻomohala mau o ka hana ʻoihana.
