Ultrafiltration ndi reverse osmosis ndi njira zamphamvu kwambiri zosefera madzi zomwe zilipo. Onsewa ali ndi zosefera zabwino kwambiri, koma amasiyana m'njira zina zazikulu. Kuti mudziwe kuti ndi iti yomwe ili yoyenera panyumba panu, tiyeni timvetsetse bwino machitidwe awiriwa.

Kodi ultrafiltration ndi yofanana ndi reverse osmosis?

No. Ultrafiltration (UF) ndi reverse osmosis (RO) ndi machitidwe amphamvu komanso ogwira mtima oyeretsera madzi koma UF imasiyana ndi RO m'njira zingapo zofunika:

• Imasefa zolimba / tinthu tating'onoting'ono ngati 0.02 micron kuphatikiza mabakiteriya. Simachotsa mchere wosungunuka, TDS, ndi zinthu zosungunuka m'madzi.
• Imatulutsa madzi pakufunika - palibe thanki yosungira yomwe imafunika
• Satulutsa madzi akukana (kusunga madzi)
• Zimagwira ntchito bwino pansi pa kupanikizika kochepa - palibe magetsi ofunikira

Kodi pali kusiyana kotani pakati pa UF ndi RO?

Mtundu waukadaulo wa membrane

Ultrafiltration imangochotsa ma particulates ndi zolimba, koma zimatero pamlingo wa microscopic; kukula kwa membrane pore ndi 0.02 micron. Mwanzeru kukoma, ultrafiltration imasunga mchere womwe umakhudza momwe madzi amakondera.

Reverse osmosis imachotsa pafupifupi chilichonse m'madzikuphatikizapo mchere wambiri wosungunuka ndi zolimba zosungunuka. Nembanemba ya RO ndi nembanemba yocheperako pang'ono yomwe ili ndi pore kukula pafupifupi0.0001 micron. Zotsatira zake, madzi a RO amakhala "osakoma" kwambiri chifukwa alibe mchere, mankhwala, ndi zinthu zina zakuthupi ndi zachilengedwe.

Anthu ena amakonda madzi awo kuti azikhala ndi mchere mmenemo (omwe UF imapereka), ndipo anthu ena amakonda madzi awo kukhala oyera komanso opanda pake (omwe RO amapereka).

Ultrafiltration ili ndi nembanemba ya ulusi wopanda pake kotero kuti ndi fyuluta yamakina pamlingo wabwino kwambiri yomwe imayimitsa tinthu tating'onoting'ono ndi zolimba.

Reverse osmosis ndi njira yomwe imalekanitsa mamolekyu. Amagwiritsa ntchito nembanemba yotheka kuti alekanitse ma inorganics ndi ma inorganics osungunuka kuchokera ku molekyulu yamadzi.

Tanki yosungira

UF imapanga madzi pazofunikira zomwe zimapita molunjika pampopi yanu yodzipatulira - palibe thanki yosungira yomwe ikufunika.

RO imafuna thanki yosungiramo chifukwa imapanga madzi pang'onopang'ono. Tanki yosungiramo imatenga malo pansi pa sinki. Kuphatikiza apo, akasinja a RO amatha kukulitsa mabakiteriya ngati sanayeretsedwe bwino nthawi zonse.Muyenera kuyeretsa dongosolo lanu lonse la RO kuphatikiza thankikamodzi pachaka.

Kutaya madzi / Kukana

Ultrafiltration samatulutsa madzi otayira (kukana) panthawi yosefera.*

Mu reverse osmosis, pali kusefa kwa cross-flow kudzera mu nembanemba. Izi zikutanthauza kuti mtsinje umodzi (permeate / mankhwala madzi) amapita ku thanki yosungirako, ndipo mtsinje umodzi ndi zonse zoipitsa ndi kusungunuka inorganics (kukana) amapita kukhetsa. Nthawi zambiri pa galoni iliyonse yamadzi a RO opangidwa,3 magaloni amatumizidwa kukhetsa.

Kuyika

Kuyika kachitidwe ka RO kumafuna kulumikizako pang'ono: chingwe choperekera chakudya, chingwe chothira madzi okanidwa, thanki yosungiramo, ndi bomba la mpweya.

Kuyika makina opangira ma ultrafiltration okhala ndi nembanemba yosinthika (yaposachedwa kwambiri muukadaulo wa UF *) kumafuna kulumikizako pang'ono: chingwe choperekera chakudya, chingwe chokhetsa kuti muthamangitse nembanemba, ndi poipi yodzipereka (yogwiritsa ntchito madzi akumwa) kapena chingwe chotulutsira (yonse). nyumba kapena ntchito zamalonda).

Kuti muyike makina opangira ma ultrafiltration opanda nembanemba yowongoka, ingolumikizani makinawo ku chingwe choperekera chakudya komanso pampopi wodzipatulira (madzi akumwa) kapena chingwe chogulitsira (nyumba yonse kapena malonda).

Kodi UF ingachepetse TDS?

Ultrafiltration sichichotsa zolimba zosungunuka kapena TDS zosungunuka m'madzi;zimangochepetsa ndikuchotsa zolimba / tinthu tating'onoting'ono. UF ikhoza kuchepetsa zinthu zolimba zosungunuka (TDS) mwangozi chifukwa ndi kusefera kopitilira muyeso, koma monga njira ya ultrafiltration sikuchotsa mchere wosungunuka, mchere wosungunuka, zitsulo zosungunuka, ndi zinthu zosungunuka m'madzi.

Ngati madzi anu omwe akubwera ali ndi mlingo wapamwamba wa TDS (kupitirira 500 ppm) ultrafiltration sichivomerezedwa; Osmosis yokhayo yomwe ingakhale yothandiza kutsitsa TDS.

Chabwino n'chiti RO kapena UF?

Reverse osmosis ndi ultrafiltration ndi machitidwe ogwira mtima komanso amphamvu omwe alipo. Pamapeto pake chomwe chili bwino ndikukonda kwanu kutengera momwe madzi anu aliri, zokonda zanu, malo, chikhumbo chosunga madzi, kuthamanga kwa madzi, ndi zina zambiri.

Njira Zamadzi Zakumwa: Ultrafiltration versus Reverse Osmosis

Nawa ena mwa mafunso akulu omwe muyenera kudzifunsa posankha ngati njira yamadzi akumwa ya ultrafiltration kapena reverse osmosis ndiyabwino kwa inu:

1. Kodi TDS yamadzi anu ndi iti? Ngati madzi anu omwe akubwera ali ndi chiwerengero chachikulu cha TDS (kupitirira 500 ppm) ultrafiltration sichivomerezedwa; Osmosis yokhayo yomwe ingakhale yothandiza kutsitsa TDS.
2. Kodi mumakonda kukoma kwa mchere m'madzi omwe mumamwa? (Ngati inde: ultrafiltration). Anthu ena amaganiza kuti madzi a RO samalawa kalikonse, ndipo ena amaganiza kuti amakoma pang'ono komanso / kapena ndi acidic pang'ono - amakukondani bwanji ndipo zili bwino?
3. Kodi madzi akuthamanga bwanji? RO imafunika osachepera 50 psi kuti igwire bwino ntchito - ngati mulibe 50psi mudzafunika mpope wolimbikitsa. Ultrafiltration imagwira ntchito bwino pazovuta zochepa.
4. Kodi mumakonda madzi otayira? Pa galoni iliyonse ya madzi a RO, pafupifupi magaloni atatu amapita kukhetsa. Ultrafiltration imapanga palibe madzi oipa.
