Ke Hoʻomaopopo nei i nā ʻenehana kānana ʻoihana

ʻOi aku ka kānana ʻoihana ma mua o ka wehe wale ʻana i nā ʻāpana mai kahi wai. ʻOkoʻa ka pahuhopu ma muli o ka noi. Makemake paha kahi hale hana waina e wehe i ka noe me ka mālama ʻana i nā mea ʻala. Pono paha kahi mea hana lāʻau lapaʻau i ka kānana sterile i hōʻoia ʻia. Hoʻoikaika ka mea hana aila ʻai i ka hoʻonui ʻana i ka throughput me ka hoʻemi ʻana i ka nalowale o ka huahana. Ma muli o ka ʻokoʻa o kēia mau pahuhopu, ua ulu nā ʻenehana kānana i ʻelua mau ʻano like ʻole:kānana hohonua mekānana membrane.

He aha ka hohonuKānanaNā pepa?

Ua haku ʻia nā pepa kānana hohonu me kahi matrix mānoanoa a porous i hana ʻia mai nā olonā cellulose, nā mea kōkua kānana e like me ka lepo diatomaceous a i ʻole perlite, a me nā resins kūikawā e hāʻawi ana i ka ikaika kūkulu a me ka adsorption electrokinetic. Ma kahi o ka hopu ʻana i nā mea haumia ma luna o ka ʻili wale nō, ua paʻa nā ʻāpana ma loko o ka mānoanoa holoʻokoʻa o ka media kānana. ʻAe kēia ʻano ʻekolu-dimensional i ke kānana e mālama i nā mea haumia o nā nui like ʻole me ka mālama ʻana i nā kahe kahe paʻa ma luna o nā holo hana lōʻihi.

Ma muli o ka hoʻolaha ʻia ʻana o nā mea haumia ma nā wahi a pau o ka pāpāho ma mua o ka hōʻiliʻili ʻana ma kahi ʻili hoʻokahi, hōʻike nā pepa kānana hohonu i ka hiki ke paʻa i ka lepo. Hoʻohana nui ʻia lākou no ka hoʻomaʻemaʻe ʻana i nā mea inu, nā aila ʻai, nā wai hoʻouluulu, nā enzymes, ka gelatin, nā mea hoʻonani, a me nā kemika maikaʻi.

He aha nā kānana membrane?

Hoʻohana nā kānana membrane i kahi membrane polymeric lahilahi me nā nui pore i kāohi nui ʻia. ʻAʻole e like me nā kānana hohonu, hilinaʻi nui nā kānana membrane ma luna okānana ʻili. Hoʻopaʻa ʻia nā ʻāpana i ʻoi aku ka nui ma mua o ka nui o ka pore ma ka ʻili o ka membrane, ʻoiai nā mole liʻiliʻi e hele ana. ʻO nā mea membrane maʻamau e komo pū me PES, PVDF, Nylon, PTFE, a me ka cellulose acetate, me nā nui o ka pore maʻamau mai 0.1 a 1.0 μm no ka microfiltration.

ʻO ko lākou hiki ke hāʻawi i ka paʻa loa e hoʻolilo i nā kānana membrane i mea kūpono no ka kānana sterile, ka wehe ʻana i ka microbial, a me nā ʻanuʻu kānana hope loa kahi e pono ai ke kūlike a me ka mālama ʻana i nā hoʻoponopono.

Pehea e hana ai kēlā me kēia ʻano kānana

Kumumanaʻo Kānana Hohonu

E noʻonoʻo i ka ninini ʻana i ka wai lepo ma o kahi huʻahuʻa mānoanoa. I ka hele ʻana o ka wai ma o ka huʻahuʻa, ua paʻa nā ʻāpana i nā hohonu like ʻole ma mua o ka hōʻiliʻili ʻana ma luna wale nō o ka ʻili. ʻO ke ʻano kēia o ke ʻanokānana hohonuhana. Hopu ʻia nā ʻāpana nui ma kahi kokoke i ka ʻili o uka, komo hohonu nā ʻāpana waena, a mālama ʻia nā mea haumia maikaʻi ma loko o ka pūnaewele pore kūloko.

Ma waho aʻe o ka interception mechanical, hoʻohana pū kekahi mau pepa kānana hohonu i ka adsorption electrokinetic. Hoʻokipa nā media kānana i hoʻopiʻi maikaʻi ʻia i nā colloids i hoʻopiʻi maikaʻi ʻole a me nā ʻāpana liʻiliʻi e hele ma waena o nā pores mechanical. Hoʻomaikaʻi nui kēia hui pū ʻana o ka paʻa mechanical a me ka electrostatic i ka pono o ka wehewehe ʻana, ʻoi aku hoʻi no nā mea inu, nā wai olaola, a me nā hopena i loaʻa ka protein.

ʻOi aku ka hana o ka kānana membrane e like me kahi kānana kikoʻī. Loaʻa i kēlā me kēia pore kahi nui i ho'ākāka ʻia, e ʻae ana i nā ʻāpana ma lalo o ka helu e hala me ka mālama ʻana i nā mea haumia nui ma luna o ka ʻili. No ka mea, ʻaneʻane hōʻiliʻili nā mea haumia āpau ma kahi papa hoʻokahi, hāʻawi nā kānana membrane i ka hana paʻa i wānana mua ʻia akā e hoʻomohala mālie i kahi papa keke e hoʻonui ai i ka hāʻule ʻana o ke kaomi a hōʻemi i ke kahe.

Hōʻike kēia ʻano i ke kumu e hoʻokomo pinepine ʻia ai nā kānana membrane ma hope o nā pae kānana mua. ʻO ka wehe ʻana i nā ʻāpana nui ma luna e hoʻolōʻihi i ke ola membrane a hoʻemi i nā kumukūʻai hana.
