ʻO nā ʻōlelo kuhikuhi nui ʻekolu e ana i ka hana o ka reverse osmosis membrane element ʻo ia ka hoʻoulu ʻana o ka wai, ka desalination rate a me ka hoʻoheheʻe ʻana o ka membrane, ka mea i hōʻike nui ʻia e ke kaomi wai hānai.
I kēia manawa, nui nā membrane reverse osmosis i kūʻai ʻia ma ka mākeke, a ma muli o nā manaʻo like ʻole, ʻaʻole like ka helu.Hoʻokaʻawale ʻia nā hōʻailona like ʻole, a ʻokoʻa nā ʻano a me nā hiʻohiʻona.I kēia lā, e kamaʻilio e pili ana i ka hoʻokaʻawale ʻana o nā membrane reverse osmosis e like me ka mea a me nā ʻano o ka mea membrane o nā mea nui.
Nā ʻano o nā membrane reverse osmosis:
1. E like me ke ʻano o ka mea membrane, hiki ke hoʻokaʻawale ʻia i ka membrane homogeneous, membrane asymmetric a me ka membrane composite.
2.According i nā hiʻohiʻona o nā mea membrane, hiki ke hoʻokaʻawale ʻia i loko o ka membrane haʻahaʻa haʻahaʻa, ultra-low pressure membrane, extreme ultra-low pressure membrane, haʻahaʻa haʻahaʻa ikehu membrane, ultra-low ikehu hoʻohana membrane, kiʻekiʻe desalination rate membrane, ultra-high desalination membrane, kiʻekiʻe boron removal membrane, nui flux membrane, anti-pollution membrane a pela aku.
3.According i ka noi o ka reverse osmosis membrane, hiki ke maheleia i loko o ka piula wai membrane, brackish wai membrane, kai desalination membrane, semiconductor papa membrane, concentrated separation membrane, thermal disinfection membrane a pela aku.
4.According i kāna mau mea maka, hiki ke hoʻokaʻawale ʻia i cellulose acetate membrane, polyamide membrane, composite membrane.
5. E like me ka nui o ka mea membrane, hiki ke hoʻokaʻawale ʻia i loko o ka membrane reverse osmosis liʻiliʻi, 4040 membrane a me 8040 membrane.
6.According i ka hoʻolālā, hiki ke hoʻokaʻawale ʻia i ka membrane inorganic, membrane organic, disc tube reverse osmosis membrane type / DTRO.
Ka hoʻokaʻawale ʻana o nā membrane reverse osmosis:
1.Cellulose acetate:
ʻO ka cellulose acetate, ka mea i ʻike ʻia he acetyl cellulose a i ʻole cellulose acetate, hoʻohana maʻamau i ka pulupulu a me ka lāʻau e like me nā mea maka e hana ai i ka cellulose acetate ma o ka esterification a me ka hydrolysis.Me ka hala ʻana o ka manawa, e emi mālie ana ka desalination rate o kēia ʻano membrane element, a ʻoi aku ka nui o ka hiki ke hoʻohaumia.
2.Polyamide:
Hiki ke hoʻokaʻawale ʻia nā polyamides i nā polyamides aliphatic a me nā polyamides aromatic.I kēia manawa, hoʻohana nui ʻia nā polyamides aromatic ma ka mākeke, nona nā koi haʻahaʻa no ka waiwai PH, akā hiki i ka chlorine manuahi ke hoʻohaumia nui iā ia.
3.Composite membrane:
ʻO ka membrane composite ka membrane osmosis maʻamau maʻamau ma ka mākeke i kēia manawa, i hana nui ʻia i nā mea ʻelua i luna, ʻo ka papa honua o kēia reverse osmosis membrane he ʻili pale pale, hiki ke pale a hoʻokaʻawale i ka paʻakai, ʻike ʻia ʻo ka desalting papa, ka mānoanoa mea maʻamau 50nm.Aia ma lalo kahi papa porous ikaika, i ʻike ʻia ʻo ka membrane base, a ʻo ka papa lalo e hoʻohana ana i nā mea i ulana ʻole ʻia ma ke ʻano he papa kākoʻo.Hoʻopau maikaʻi ka membrane composite i nā hemahema o nā mea ʻelua i luna aʻe, a loaʻa iā ia nā pōmaikaʻi o ka hopena kiʻekiʻe kiʻekiʻe, ka wai nui a me ka hoʻohana nui ʻana.
Hāʻawi mākou ʻo Weifang Toption Machinery Co., Ltd i nā ʻano mea hoʻomaʻemaʻe wai āpau a me nā lako me nā membrane RO.Inā makemake ʻoe i ka ʻike hou aku, e kipa i kā mākou pūnaewele www.toptionwater.com.A i ʻole inā he pono kāu, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou.
