Nā Kuhikuhi no ka Hoʻohana Kūpono ʻana o nā Membranes Osmosis Hoʻohuli RO
- ʻŌlelo Aʻo! Hiki i kēia mau hana kūpono ʻole ke hōʻino pololei i ka membrane osmosis hoʻohuli RO
ʻIke ʻia ka hana o nā membrane osmosis hoʻohuli RO he paʻa, akā hiki i nā hemahema hana liʻiliʻi ke alakaʻi i ka hāʻule mua ʻana, i kau nui ʻia ma ʻekolu mau ʻano o nā pilikia.
ʻO ke kinoea koena i hoʻokuke ʻole ʻia ma lalo o ke kaomi kiʻekiʻe hiki ke hana i ka "hammer pneumatic" e hōʻino i ka membrane
Ke hana ke kinoea i koe i loko o nā lako ma lalo o nā kūlana kaomi kiʻekiʻe, hiki iā ia ke hana i kahi "hopena hāmare wai," e hoʻopilikia pololei ana i nā ʻāpana membrane a e hōʻino kino ai. Hoʻomaka pinepine kēia kūlana ma nā hiʻohiʻona ʻelua:
Ke hoʻomaka hou ka lako, ʻaʻole i hoʻomaʻemaʻe piha ʻia ke kinoea: Ma hope o ka hoʻomaʻemaʻe ʻana i nā lako, e hoʻomaka hou i ka hana. Inā ʻaʻole i hoʻokuʻu piha ʻia ka ea a hoʻonui koke ʻia ke kaomi, e hoʻopilikia nui ke kinoea i koe i ka membrane. ʻO ke kaʻina hana pololei, ʻo ia ka hana ma kahi kaomi haʻahaʻa o 2 ~ 4 bar mua, a hoʻonui mālie i ke kaomi ke ʻike ʻole ʻia nā pehu i loko o ka mika kahe (e hōʻike ana i ka wehe piha ʻana o ka ea).
ʻO ka sila ʻana o ka paipu maikaʻi ʻole e ʻae i ka komo ʻana o ka ea: Inā liki ka pilina ma waena o nā lako hana mua (e like me ka microfilter) a me ka pamu kaomi kiʻekiʻe a i ʻole ua sila pono ʻole ʻia, ʻo ka lawa ʻole o ka lako wai mua (e like me ka emi ʻana o ke kahe ma muli o ke kāpili ʻana o ka microfilter) e hana i kahi hakahaka i loko o ka paipu, e alakaʻi ana i ka omo ʻana o ka ea. ʻO nā hoʻonā e komo pū me ka hoʻomaʻemaʻe koke ʻana a i ʻole ka hoʻololi ʻana i ka microfilter i paʻa, ka nānā ʻana a me ka hoʻoponopono ʻana i nā paipu e liki ana, a me ka hōʻoia ʻana ʻaʻohe ea e komo i ka wā hana.
- ʻO ke ʻano pani hewa e alakaʻi ai i ka scaling kiʻiʻoniʻoni a me ka haumia
Manaʻo ka poʻe he nui "ʻo ka pani ʻana = ka mana koke ʻana," akā hiki i kēia ke waiho i nā pilikia huna no nā membrane RO, ʻo ia hoʻi nā pilikia ʻelua:
ʻO ka hōʻemi ʻana i ke kaomi me ka ʻole o ka holoi ʻana hiki ke alakaʻi i ka scaling ma ka ʻaoʻao concentrate: I ka wā o ka hana membrane RO, ʻoi aku ka kiʻekiʻe o ka paʻakai inorganic ma ka ʻaoʻao concentrate ma mua o ka wai hānai. Inā hoʻemi koke ʻia ke kaomi ma hope o ka pani ʻana me ka ʻole o ka holoi pono ʻana, e pipili nā paʻakai inorganic i loko o ka concentrate i ka ʻili o ka membrane, a laila e hana i nā waihona unahi e pani ai i nā pores membrane a hōʻemi i ka pono o ka kānana i ka hala ʻana o ka manawa.
Holoi me ka wai i loaʻa nā reagents kemika: Holoi kekahi poʻe hoʻohana i nā ʻāpana membrane me ka wai mālama mua i loaʻa nā reagents kemika, ʻaʻole ia he mea kūpono. I ka wā e hoʻopau ai nā lako, hiki i nā reagents kemika wai ke hana me ka membrane a waiho paha i nā koena e haumia ai ka membrane, e hoʻopilikia ana i ka maikaʻi o ka effluent ma hope.
- ʻO ka disinfection a me ka mālama pono ʻole hiki ke alakaʻi i ka "colonization" microbial o ka membrane
ʻO ka mea polyamide composite kahi koho maʻamau no nā membrane RO, akā he hemahema kona: ke kūpaʻa maikaʻi ʻole i ke koena chlorine. Inā ʻaʻole i hoʻokomo pono ʻia nā disinfectants e like me ka chlorine i ka wā o ka hana, me ka nānā ʻole ʻia i ka haumia microbial, e ulu nui nā bacteria a me nā microorganisms i loko o ka wai ma luna o ka ʻili o ka membrane, e hana ana i nā biofilms. ʻAʻole wale kēia e pani i nā pores membrane akā alakaʻi pū kekahi i ka haumia microbial i loko o ka wai output (ʻo ke kumu o nā pae microbial wai maʻemaʻe o nā mea hana he nui ma aneʻi).
