Kusefa madzi pogwiritsa ntchito njira ya Ultrafiltration ndi reverse osmosis ndi njira zamphamvu kwambiri zosefera madzi zomwe zilipo. Zonsezi zili ndi makhalidwe abwino kwambiri osefera, koma zimasiyana m'njira zina zofunika. Kuti tidziwe chomwe chili choyenera panyumba panu, tiyeni timvetse bwino njira ziwirizi.

Kodi kufinyira kwa ultrafiltration ndi kofanana ndi kufinyira kwa reverse osmosis?

Ayi. Kufinyira madzi m'njira ya Ultrafiltration (UF) ndi reverse osmosis (RO) ndi njira zamphamvu komanso zothandiza zochizira madzi koma UF imasiyana ndi RO m'njira zingapo zofunika:

• Imasefa zinthu zolimba/tinthu tating'onoting'ono tomwe tili ndi ma micron 0.02 kuphatikiza mabakiteriya. Sichotsa mchere wosungunuka, TDS, ndi zinthu zosungunuka m'madzi.
• Amapanga madzi nthawi iliyonse akafuna - thanki yosungiramo madzi siifunika
• Sizitulutsa madzi okanidwa (kusunga madzi)
• Imagwira ntchito bwino ikapanikizika pang'ono - sipafunika magetsi

Kodi kusiyana pakati pa UF ndi RO ndi kotani?

Mtundu wa ukadaulo wa nembanemba

Kusefa kwa ultrafiltration kumachotsa tinthu tating'onoting'ono ndi tolimba, koma kumatero pamlingo wa microscopic; kukula kwa membrane pore ndi 0.02 micron. Poganizira kukoma, kusefa kwa ultrafiltration kumasunga mchere zomwe zimakhudza momwe madzi amakondera.

Reverse osmosis imachotsa pafupifupi chilichonse m'madzikuphatikizapo mchere wambiri wosungunuka ndi zinthu zolimba zosungunuka. Nembanemba ya RO ndi nembanemba yomwe imatha kulowa mkati mwake yomwe ili ndi kukula kwa ma pore pafupifupi0.0001 maikuloniZotsatira zake, madzi a RO ndi "osakoma" chifukwa alibe mchere, mankhwala, ndi zinthu zina zachilengedwe komanso zopanda organic.

Anthu ena amakonda madzi awo kukhala ndi mchere (zomwe UF imapereka), ndipo ena amakonda madzi awo kukhala oyera komanso opanda kukoma (zomwe RO imapereka).

Kufinyira kwa ultrafiltration kuli ndi nembanemba yopanda kanthu ya ulusi kotero kwenikweni ndi fyuluta yamakina pamlingo wabwino kwambiri yomwe imaletsa tinthu tating'onoting'ono ndi zinthu zolimba.

Reverse osmosis ndi njira yomwe imalekanitsa mamolekyu. Imagwiritsa ntchito nembanemba yolowa madzi pang'ono kuti ilekanitse zinthu zosapangidwa ndi zamoyo ndi zinthu zosapangidwa ndi zamoyo zomwe zimasungunuka kuchokera ku molekyulu yamadzi.

Thanki yosungiramo zinthu

UF imapanga madzi akafunika ndipo amapita molunjika ku pompopu yanu yapadera - sipafunika thanki yosungira madzi.

RO imafuna thanki yosungiramo zinthu chifukwa imapanga madzi pang'onopang'ono kwambiri. Thanki yosungiramo zinthu imatenga malo pansi pa sinki. Kuphatikiza apo, matanki a RO amatha kubzala mabakiteriya ngati sakutsukidwa bwino nthawi zonse.Muyenera kuyeretsa dongosolo lanu lonse la RO kuphatikiza thankikamodzi pachaka.

Madzi Otayira / Kukana

Kusefa kwa ultrafiltration sikutulutsa madzi otayika (osaloledwa) panthawi yosefa.

Mu reverse osmosis, pali kusefa kwa cross-flow kudzera mu nembanemba. Izi zikutanthauza kuti mtsinje umodzi (madzi olowa/opangidwa) umapita ku thanki yosungiramo zinthu, ndipo mtsinje umodzi wokhala ndi zodetsa zonse ndi zinthu zosasungunuka (zokana) umapita kukatulutsa madzi. Kawirikawiri pa galoni imodzi iliyonse ya madzi a RO omwe amapangidwa,Magaloni atatu amatumizidwa kuti akatulutse madzi.

Kukhazikitsa

Kukhazikitsa makina a RO kumafuna kulumikizana pang'ono: chingwe choperekera chakudya, chingwe chotulutsira madzi otayika, thanki yosungiramo zinthu, ndi pompopu yopanda mpweya.

Kukhazikitsa makina oyeretsera madzi pogwiritsa ntchito nembanemba yotha kusungunuka (ukadaulo waposachedwa wa UF *) kumafuna kulumikizana pang'ono: chingwe choperekera madzi, chingwe chotulutsira madzi kuti mutulutse nembanemba, ndi pompopu yapadera (yomwe imagwiritsa ntchito madzi akumwa) kapena chingwe chotulutsira madzi (yomwe imagwiritsa ntchito nyumba yonse kapena malo ogulitsira).

Kuti muyike makina oyeretsera madzi ambiri opanda nembanemba yotha kusungunuka, ingolumikizani makinawo ku chingwe choperekera madzi ndi ku pompopu yapadera (madzi ogwiritsira ntchito madzi) kapena chingwe chotulutsira madzi (nyumba yonse kapena malo ogulitsira).

Kodi UF ingachepetse TDS?

Kusefa kwa ultrafiltration sikuchotsa zinthu zolimba zosungunuka kapena TDS zosungunuka m'madzi;Zimangochepetsa ndikuchotsa zinthu zolimba/tinthu tating'onoting'ono. UF ingachepetse zinthu zina zosungunuka (TDS) mwangozi chifukwa ndi kusefa kwabwino kwambiri, koma monga njira yodziwira, kusefa kwapadera sikuchotsa mchere wosungunuka, mchere wosungunuka, zitsulo zosungunuka, ndi zinthu zosungunuka m'madzi.

Ngati madzi omwe akubwera ali ndi TDS yambiri (yoposa 500 ppm), kufinyira madzi m'madzi sikuvomerezeka; kufinyira madzi m'madzi kokha ndiko komwe kungathandize kuchepetsa TDS.

Ndi iti yabwino kuposa RO kapena UF?

Njira zosinthira madzi ndi kufinyira madzi m'madzi ndi njira zogwira mtima komanso zamphamvu kwambiri. Chomwe chili chabwino ndi kusankha kwanu kutengera momwe madzi anu alili, kukoma kwanu, malo anu, chikhumbo chanu chosunga madzi, kuthamanga kwa madzi, ndi zina zambiri.

Machitidwe a Madzi Omwa: Kusefa kwa Ultra poyerekeza ndi Osmosis Yobwerera M'mbuyo

Nazi zina mwa mafunso akuluakulu oti mudzifunse posankha ngati njira yothira madzi akumwa ya ultrafiltration kapena reverse osmosis ndi yabwino kwa inu:

1. Kodi TDS ya madzi anu ndi yotani? Ngati madzi omwe akubwera ali ndi TDS yambiri (yoposa 500 ppm), kufinyira madzi m'madzi sikuvomerezeka; kufinyira madzi m'madzi okha ndi komwe kungathandize kuchepetsa TDS.
2. Kodi mumakonda kukoma kwa mchere m'madzi anu kuti mumwe? (Ngati inde: ultrafiltration). Anthu ena amaganiza kuti madzi a RO sakoma chilichonse, ndipo ena amaganiza kuti amakoma pang'ono komanso/kapena ali ndi asidi pang'ono - kodi amakoma bwanji kwa inu ndipo kodi zili bwino?
3. Kodi kuthamanga kwa madzi anu ndi kotani? RO imafunika osachepera 50 psi kuti igwire ntchito bwino - ngati mulibe 50psi mudzafunika pampu yolimbikitsira. Kufinyira madzi mopitirira muyeso kumagwira ntchito bwino pakakhala kuthamanga kochepa.
4. Kodi mumakonda madzi otayira? Pa galoni imodzi iliyonse ya madzi a RO, pafupifupi magaloni atatu amapita ku ngalande. Kufinyira madzi m'njira ya ultrafiltration sikubweretsa madzi otayira.
