ʻO ke kānana kahi ʻano hana kino maʻamau i hoʻohana ʻia e wehe i nā mea hiki ʻole ke hoʻoheheʻe ʻia mai nā wai. Ma muli o ka ʻoiaʻiʻo he mau ʻāpana maikaʻi, amorphous, sticky nā mea paʻa i loko o nā wai, a maʻalahi hoʻi e ālai i nā lua lole kānana, inā kānana ʻokoʻa ʻia, kū pinepine nā pilikia e like me ka paʻakikī i ke kānana ʻana a me ka filtrate maopopo ʻole, ʻaʻole hiki ke hoʻopili ʻia ma ka hana. Inā hoʻohui ʻia kahi mea kōkua kānana i ka hopena a i ʻole ua uhi mua ʻia kahi papa o ke kōkua kānana ma luna o ka ʻili o ka lole kānana, hiki iā ia ke hoʻomaikaʻi nui i kēia kūlana. He wikiwiki ka wikiwiki o ke kānana ʻana, ua moakāka ka filtrate, a ua paʻa loa ke koena kānana, hiki ke hoʻokaʻawale ʻia mai ka lole kānana. ʻO ke kōkua kānana i hoʻohana pinepine ʻia ma nā ʻoihana like ʻole, ʻo ia ka lepo diatomaceous. ʻO ia ka mea a mākou e kapa pinepine ai he mau mea kōkua kānana honua diatomaceous.

ʻO ke kōkua kānana honua diatomaceous kahi ʻano hou o ka medium kānana pauka kiʻekiʻe i hana ʻia a hana ʻia me ka hoʻohana ʻana i ka lepo diatomaceous ma ke ʻano he mea maka kumu ma o nā kaʻina hana pani mau e like me ka mālama mua ʻana, ka hoʻokaʻawale ʻana, ka hoʻohuihui ʻana, ka calcination, a me ka grading. Hiki iā ia ke hana i kahi keke kānana paʻa paʻa, hiki ke kāohi i nā ʻāpana liʻiliʻi i loko o ka wai kānana mua i loko o nā haumia colloidal ma ka iwi lattice. No laila, he permeability maikaʻi kona a hāʻawi i kahi ʻano keke kānana porous, me ka porosity o 85-95%, hiki ke hoʻokō i kahi ratio kahe kiʻekiʻe i ke kaʻina hoʻokaʻawale o ka paʻa a me ka wai, a hiki ke kānana i nā mea paʻa i hoʻokuʻu ʻia. Loaʻa i nā kōkua kānana honua diatomaceous ke kūpaʻa kemika maikaʻi a hiki ke hoʻopili pono ʻia i ka kānana ʻana o kekahi wai koe wale nō ka hopena caustic i hoʻopaʻa ʻia. ʻAʻole lākou e haumia i ka wai i kānana ʻia a kūlike me nā koi maʻamau o ke Kānāwai Hoʻomaʻemaʻe Meaʻai. A hiki ke hoʻohana maikaʻi ʻia ma nā media e like me ka lole kānana, ka pepa kānana, ka ʻupena uea metala, nā keramika porous, a pēlā aku. Hiki iā ia ke hoʻokō i nā hopena kānana maikaʻi ma nā mīkini kānana like ʻole a loaʻa nā pono o nā media kānana ʻē aʻe. Ke lilo nei ka hoʻohana ʻana i nā mea kōkua kānana honua diatomaceous i mea laha nui. Hoʻohana ʻia i ka ʻoihana e hana i nā mea kānana. Hoʻohana ʻia i ka ʻoihana meaʻai no ka kānana ʻana i ka pia, nā pīpī hua, nā wai huaʻai, nā mea inu like ʻole, nā syrups, nā ʻaila mea kanu, nā hoʻomākaukau enzyme, ka waikawa citric, a pēlā aku. Hoʻohana ʻia i ka ʻoihana kemika no ka kānana ʻana i nā dyes, coatings, electroplating, solvents, acids, electrolytes, synthetic resins, chemical fibers, glycerol, emulsion, a pēlā aku. Hoʻohana ʻia i ka ʻoihana lāʻau lapaʻau no ka kānana ʻana i nā antibiotics, glucose, a me nā extracts lāʻau lapaʻau kuʻuna Kina. No ka palekana o ke kaiapuni, hoʻohana ʻia no ka mālama ʻana i ka wai e hoʻomaʻemaʻe i ka wai kūlanakauhale, ka wai ʻauʻau, ka wai ʻino, ka wai ʻino ʻoihana, a pēlā aku.

1, Kōkua kānana honua diatomaceous: He ʻano kōkua kānana honua diatomaceous i hana ʻia ma o ka hoʻomaloʻo ʻana, ka calcination, ka luku ʻana, a me ka grading, hiki ke hoʻohana ʻia no nā ʻano hoʻokaʻawale wai-paʻa like ʻole. Ua koho ʻia nā ʻano kōkua kānana honua diatomaceous like ʻole no nā hoʻokaʻawale wai-paʻa like ʻole. Hoʻohana nui ʻia i ka hoʻolālā. Hoʻohana nā ʻano he nui i ke ʻano porous o ka lepo diatomaceous a me nā pūpū silica. I ka wā o ka hana ʻana, pono e uku ʻia ka nānā ʻana i ka mālama ʻana i ke ʻano a me ke ʻano kūikawā o nā iwi diatomaceous, ke koho pono ʻana i nā lako hana kuʻi a wili kūpono a me nā kūlana loea, a me ka mālama ʻana i ka pono o ke ʻano diatomaceous e like me ka hiki ke pale aku i ka ʻāpana lua. ʻO ka lako hana wili i hoʻohana pinepine ʻia he mea haki kahe ʻana o ka ea.
2, ʻO nā hana koʻikoʻi ʻekolu o ke kōkua kānana honua diatomaceous: 1. Ka hopena kānana. He hopena kānana ʻili kēia. Ke kahe ka wai ma o ka lepo diatomaceous, ʻoi aku ka liʻiliʻi o nā pores o ka lepo diatomaceous ma mua o ka nui o nā ʻāpana o nā ʻāpana haumia, no laila ʻaʻole hiki i nā ʻāpana haumia ke hele ma waena a ua keʻakeʻa ʻia. Ua kapa ʻia kēia hopena he hopena kānana. 2. I ka wā o ka kānana hohonu, hana ʻia ke kaʻina hana hoʻokaʻawale i loko o ka medium, me kekahi o nā ʻāpana liʻiliʻi e hele ana ma o ka ʻili o ke keke kānana e ālai ʻia e nā pores i loko o ka lepo diatomaceous. ʻO ka hiki ke kānana i nā ʻāpana paʻa e pili pono ana i ka nui a me ke ʻano o nā ʻāpana paʻa a me nā pores.
3, ʻO ka Adsorption e pili ana i ka hoʻokumu ʻia ʻana o nā hui kaulahao ma waena o nā ʻāpana i huki ʻia e nā uku kū'ē, a laila e pili pono ana i ka lepo diatomaceous.
