ʻO ka ʻokoʻa ma waena o nā mea hana ultrafiltration a me nā mea hana reverse osmosis

ʻO ka ʻokoʻa nui ma waena o ka membrane ultrafiltration a me ka reverse osmosis ka ʻokoʻa i ka nui o ka pore. ʻO ka nui o ka pore o ka moku o ka membrane reverse osmosis he hoʻokahi pakeneka o ka membrane ultrafiltration, a ʻoi aku ka kiʻekiʻe o ka kānana pono ʻana o ka membrane reverse osmosis ma mua o ka membrane ultrafiltration. ʻO ka membrane ultrafiltration i hoʻohālikelike ʻia me ka membrane osmosis hoʻohuli, ʻoi aku ka liʻiliʻi o ka puka o ka osmosis membrane ma mua o ka membrane ultrafiltration, ʻo 0.0001 micron ka puka ʻana o ka membrane osmosis, ʻo 0.001 micron ka puka ʻana o ka membrane ultrafiltration. ʻO ka nui o ka pore o ka membrane reverse osmosis he hoʻokahi pakeneka o ka membrane ultrafiltration, no laila ʻoi aku ka maʻemaʻe o ka wai i kānana ʻia e ka membrane osmosis reverse ma mua o ka membrane ultrafiltration.

ʻO ka membrane Ultrafiltration kahi hana hoʻokaʻawale membrane kahi i loaʻa ai i ka membrane kahi ʻano asymmetric porous. ʻO ke kaʻina kānana he kaʻina hoʻokaʻawale hoʻonā e pili ana i ke kumu sieving mechanical o ka ʻokoʻa puʻe ma waena o nā ʻaoʻao ʻelua o ka membrane, ʻo ke kaomi hana maʻamau ka 0.01 a 0.03Mpa, a ʻo ka nui o ka pore maikaʻi o ka membrane ultrafiltration ma kahi o 0.001 a 0.01 microns. He 1,000-500,000 daltons ka paona molekole interception, no laila ua manaʻo ʻia ke kaʻina hoʻokaʻawale ʻana o ka membrane ultrafiltration he kaʻina hoʻokaʻawale kino.

ʻO ka membrane osmosis reverse he membrane semi-permeable artificial me nā waiwai kikoʻī i hana ʻia e ka hoʻohālikelike ʻana i kahi membrane semi-permeable biological. ʻO RO ka ʻōlelo Pelekane o ka reverse osmosis membrane, ʻo Kina ke ʻano o ka reverse osmosis. Ka nui o ka wai kahe mai ka haʻahaʻa a i ke kiʻekiʻe. Ke kaomi ʻia ka wai, kahe ka wai mai luna a haʻahaʻa. Kapa ʻia kēia ʻo ka loina o ka reverse osmosis. ʻO ka puka o ka membrane reverse osmosis he ʻelima miliona (0.0001 micron) o ka lauoho kanaka. He 5,000 ka nui o ka ma'i bacteria a me ka ma'i ma'i, e 'ae ana i na molekule wai wale no a me kekahi mau iona mineral pono e hele aku, a'o na mea haumia a me na metala kaumaha e kipaku ia mai na paipu wai.

ʻO ka puka o ka membrane reverse osmosis he 1/100 o ka puka o ka membrane ultrafiltration, a hiki i ka filtration pololei o ka RO reverse osmosis membrane hiki i 0.0001 micron. Eia naʻe, ʻo ka pololei kānana o ka membrane ultrafiltration he 0.001 microns. No laila, hiki i nā membrane reverse osmosis ke hoʻoneʻe i nā metala kaumaha, pesticides, chloroform a me nā mea haumia kemika mai ka wai, akā ʻaʻole hiki i nā membrane ultrafiltration. Hoʻopau ka membrane ultrafiltration i nā mea pollutant a me nā hua bacteria, a hoʻoneʻe ka osmosis hoʻohuli iā lākou i ka mana loa.
