ʻAgent Denitrifying Bacteria no ka mālama ʻana i ka wai ʻino
ʻO kā mākouAgena Bakteria Denitrifyinghe mea hoʻohui olaola kiʻekiʻe i hoʻomohala kūikawā no ka wikiwiki ʻana i ka wehe ʻana o ka nitrate (NO₃⁻) a me ka nitrite (NO₂⁻) i nā ʻōnaehana mālama wai ʻino. Me kahi hui ikaika o ka bacteria denitrifying, enzymes, a me nā mea hoʻoulu olaola, hoʻomaikaʻi kēia mea hana i ka maikaʻi o ka lawe ʻana i ka nitrogen, hoʻopaʻa i ka hana ʻōnaehana, a kōkua i ka mālama ʻana i kahi pōʻai kaulike nitrification-denitrification i nā noi municipal a me nā ʻoihana.
Ke ʻimi nei i nā ʻoluʻolu hoʻohemo ʻana i ka amonia? Hāʻawi pū mākou i nā Agents Nitrifying Bacteria e hoʻopiha i kēia huahana i kahi hoʻolālā hoʻokele nitrogen piha.

Hoʻolālā ʻia kēia ʻano hana e hana ma lalo o nā kūlana haʻahaʻa-oxygen (anoxic), e wāwahi ana i ka nitrate a me ka nitrite i loko o ke kinoea nitrogen ʻinoʻino (N₂), ʻoiai ke kūʻē nei i nā mea ʻawaʻawa maʻamau a kōkua i ka hoʻihoʻi hou ʻana o ka ʻōnaehana ma hope o nā haʻalulu haʻalulu.
Nā Hana Nui
1. Hoʻopau maikaʻi i ka Nitrate a me ka Nitrite
Hoʻololi i ka NO₃⁻ a me ka NO₂⁻ i ke kinoea nitrogen (N₂) ma lalo o nā kūlana haʻahaʻa-oxygen.
Kākoʻo i ka hoʻopau piha ʻana i ka nitrogen biological (BNR)
Hoʻopaʻa i ka maikaʻi o ka effluent a hoʻomaikaʻi i ka hoʻokō ʻana i nā palena hoʻokuʻu nitrogen
2. Hoʻihoʻi hou ʻana i ka ʻōnaehana wikiwiki ma hope o nā haʻalulu haʻalulu
Hoʻonui i ke kūpaʻa i ka wā o ka loli ʻana o ka ukana a i ʻole ka hoʻololi koke ʻana
Kōkua i ka hoʻihoʻi koke ʻana i ka hana denitrification ma hope o nā pilikia kaʻina
3. Hoʻoikaika i ka holoʻokoʻa holoʻokoʻa Nitrogen Cycle
Hoʻopiha i nā kaʻina hana nitrifying ma o ka hoʻomaikaʻi ʻana i ke koena nitrogen downstream
Hoʻemi i ka hopena o ka DO haʻahaʻa a i ʻole nā ʻano kumu kalapona i ka denitrification
