ʻO ke kumu hana o ka kānana membrane ceramic e pili ana i ka microporous structure o nā membrane ceramic. Ke hele ka mea wai e kānana ʻia i kahi kaomi, e hoʻopili ʻia nā ʻāpana like ʻole o ka mea wai ma kekahi ʻaoʻao o ka ʻili o ka membrane seramika, aʻo ka wai maʻemaʻe e komo i kekahi ʻaoʻao o ka ʻili membrane, a laila e loaʻa ai ka hoʻokaʻawale wai. a me ka kānana. Hoʻokumu ʻia ke kiʻi ʻoniʻoni seramika me nā pōhaku liʻiliʻi like ʻole e like me nā ʻāpana seramika, e hana ana i nā pores ma waena o lākou. ʻO ka nui o ka pore he 20-100 nanometers wale nō, e hiki ai iā ia ke hoʻokaʻawale pono i nā mea o nā nui molekala like ʻole.

I loko o kahi ʻōnaehana kānana membrane ceramic, maʻamau ka rotor i haku ʻia me nā ʻāpana he nui o nā papa kānana seramika, a me nā ʻāpana e like me ke poʻo hāʻawi, agitator, scraper, a me nā mea ʻē aʻe. ka pae wai o ka slurry i loko o ka pahu, e hana ana i kahi papa o ka hōʻiliʻili paʻa. Ke haʻalele ka papa kānana i ka pae wai o ka slurry, e hana nā ʻāpana paʻa i kahi keke kānana a hoʻomau i ka dehydrate ma lalo o ka momi, e hoʻomaloʻo hou i ka keke kānana. Ma hope iho, e huli ka rotor i kahi i hoʻolako ʻia me kahi scraper e wehe i ka kānana keke a lawe ʻia e kahi mea lawe kāʻei i kahi i makemake ʻia.
