Hoʻohana nui ʻia ʻo DMDC i ka wai huaʻai a ʻoi aku kona ʻenehana.Hoʻopili ʻia ka hopena sterilization o DMDC i ka wai hua e ke ʻano a me ke kānana o ka wai huaʻai, a ʻo ka hoʻohana pū ʻana o DMDC a me nā ʻenehana sterilization e hiki ke hoʻomaikaʻi nui i ka hopena sterilization.
He wai kala ʻole ʻo Dimethyl Dicarbonate (DMDC) me kahi ʻala ʻala iki.Hoʻohana mua ʻia ʻo ia ma ke ʻano he mea mālama inu, kōkua hoʻoponopono, a i ʻole sterilant (Helu 242).ʻOi aku ka maikaʻi o ka hoʻohana ʻana o DMDC i ka wā e pono ai ke hoʻomaʻemaʻe ʻia ka waina akā ʻaʻole hiki ke kānana ʻia, pasteurized, a i ʻole sulfured.Hoʻohana pū ʻia ʻo DMDC no ka hoʻopaʻa ʻana i nā mea inu ʻole e like me nā mea inu wai kalapona a i ʻole nā mea inu ʻona, nā mea inu haʻuki isotonic, nā kī hau, a me nā wai ʻono.
Hiki i ka DMDC ke komo i ka membrane cell a launa pū me nā enzymes i loko o nā microorganisms e ālai i ka metabolism, no laila e loaʻa ai ka hopena bactericidal.ʻOiai ma nā haʻahaʻa haʻahaʻa loa, hiki i ka DMDC ke pepehi maikaʻi i ka mea inu maʻamau spoilage bacteria me ka pili ʻole i ka ʻono, ka ʻono a me ke kala o ka mea inu.Eia hou, hiki i ka DMDC ke hoʻoheheʻe koke ʻia a piha i ka hydrolyzed e ʻike i ka nui o ka carbon dioxide a me ka methanol i loko o nā mea inu.He mea hoʻohui maoli nō kēia i ka wai hua.

ʻO ka sterilization anuanu o kēia mau ʻano mea inu: nā mea inu hua, nā mea inu ikaika (me ka carbon dioxide a i ʻole ʻole), nā mea inu kī (me ka carbon dioxide a i ʻole ʻole), nā mea inu wai hua (me ka carbon dioxide a i ʻole, ʻike wai hua i 100% ).
