  • ʻO ka oxygen dissolved kahi ana o ka nui o ka oxygen kinoea i loko o ka wai.Pono nā wai olakino e kākoʻo i ke ola e loaʻa i ka oxygen dissolved (DO).
    Komo ka Oxygen Dissolved i ka wai ma o:
    ka omo pololei mai ka lewa.
    ka neʻe wikiwiki ʻana mai ka makani, ka nalu, ke au a i ʻole ka ʻenekini mechanical.
    ʻO ka photosynthesis ola mea kanu i loko o ka wai ma ke ʻano he hopena o ka hana.

    ʻO ke ana ʻana i ka oxygen i hoʻoheheʻe ʻia i loko o ka wai a me ka mālama ʻana e mālama i nā pae DO kūpono, he hana koʻikoʻi ia i nā ʻano noi lapaʻau wai.ʻOiai pono ka oxygen dissolved e kākoʻo i ke ola a me nā kaʻina hana lapaʻau, hiki nō hoʻi ke hōʻino, e hoʻoulu ai i ka oxidation e hōʻino i nā mea hana a hoʻololi i ka huahana.Hoʻopilikia ka oxygen dissolved:
    ʻAno maikaʻi: Hoʻoholo ka manaʻo DO i ka maikaʻi o ka wai kumu.Me ka lawa ʻole o DO, lilo ka wai i ʻino a maikaʻi ʻole e pili ana i ka maikaʻi o ke kaiapuni, ka wai inu a me nā huahana ʻē aʻe.

    Hoʻokō Hoʻoponopono: No ka hoʻokō ʻana i nā lula, pono pinepine ka wai ʻino e loaʻa kekahi mau manaʻo o DO ma mua o ka hiki ke hoʻokuʻu ʻia i loko o kahi kahawai, loko, muliwai a i ʻole ala wai.Pono e loaʻa i nā wai olakino e kākoʻo i ke ola.

    Ka Mana Kaʻina Hana: He mea koʻikoʻi nā pae DO no ka hoʻomalu ʻana i ka mālama ola kino o ka wai ʻōpala, a me ka pae biofiltration o ka hana wai inu.Ma kekahi mau noi ʻoihana (e laʻa i ka hana mana) he mea ʻino kekahi DO no ka hana mahu a pono e wehe ʻia a pono e hoʻopaʻa paʻa ʻia kona ʻike.
