Cha. I-Ultrafiltration (UF) ne-reverse osmosis (RO) amasistimu okwelapha amanzi anamandla futhi asebenzayo, kodwa i-UF ihluka ku-RO ngezindlela ezimbalwa ezibalulekile:
Ihlunga izinto eziqinile/izinhlayiya ezincane njengo-0.02 microns, okuhlanganisa amagciwane. Ayikwazi ukususa amaminerali ancibilikisiwe, i-TDS nezinto ezincibilikisiwe emanzini.
Khiqiza amanzi uma kudingeka - awekho amathangi okugcina adingekayo
Awekho amanzi angcolile akhiqizwayo (ukonga amanzi)
Isebenza kahle ku-voltage ephansi - awukho ugesi odingekayo
Uyini umehluko phakathi kwe-ultrafiltration ne-osmosis ehlehlayo?
Uhlobo lobuchwepheshe be-Membrane
I-Ultrafiltration isusa izinhlayiya nezinto eziqinile kuphela, kodwa ikwenza ngezinga elincane kakhulu; ulwelwesi pore usayizi 0.02 microns. Mayelana nokunambitheka, i-ultrafiltration igcina amaminerali, okuthinta ukunambitheka kwamanzi.
I-Reverse osmosis iqeda cishe yonke into emanzini, kuhlanganise namaminerali amaningi ancibilikisiwe kanye nezinto eziqinile ezincibilikisiwe. Ulwelwesi lwe-RO luwulwelwesi olungangeneka kalula olunosayizi wembotshana olinganiselwa ku-0.0001 microns. Ngakho-ke, amanzi e-RO cishe “awanaphunga” ngoba awanawo amaminerali, amakhemikhali, nezinye izinhlanganisela eziphilayo nezingaphili.
Abanye abantu bathanda amanzi abo ukuthi abe namaminerali (ngenhlonipho ye-UF), abanye bathanda amanzi abo ukuthi ahlanzeke ngokuphelele futhi angabi naphunga (ngenhlonipho ye-RO).
I-Ultrafiltration inolwelwesi lwefayibha engenalutho, ngakho-ke isihlungi semishini sezinga eliphezulu kakhulu esivimba izinhlayiya nezinto eziqinile.
I-Reverse osmosis iyinqubo ehlukanisa ama-molecule. Isebenzisa i-semi-permeable membrane ukuze ihlukanise i-inorganics kanye ne-inorganics encibilikisiwe kuma-molecule amanzi.
INAstewater/Yenqaba
I-Ultrafiltration ayikhiqizi amanzi angcolile (imikhiqizo engcolile) phakathi nenqubo yokuhlunga*
Ku-osmosis ehlanekezela, kukhona ukuhlungwa kwe-cross-flow ngolwelwesi. Lokhu kusho ukuthi umfudlana wamanzi (amanzi/amanzi omkhiqizo) ungena ethangini lokugcina futhi umfudlana wamanzi oqukethe konke ukungcola kanye nezinto ezingaphili ezincibilikisiwe (udoti) ungena emseleni. Ngokuvamile, ku-1 gallon yamanzi e-osmosis e-reverse akhiqizwayo, amalitha ama-3 athunyelwa emanzini.
Faka
Ukufaka isistimu ye-osmosis ehlehlayo kudinga ukuxhumana okumbalwa: izintambo zokuphakela amanzi, izintambo zokulahla amanzi angcolile, amathangi okugcina, nompompi begebe lomoya.
Iyafakaisistimu yokuhlunga kakhulu enolwelwesi oluguquguqukayo (okwakamuva kubuchwepheshe bokuhlunga kwe-ultrafiltration*) idinga ukuxhumana okumbalwa: ulayini wokuphakelayo, umugqa wokudonsa amanzi wokusula ulwelwesi, kanye nompompi ozinikele (izicelo zamanzi okuphuza) noma ulayini wokuphakelayo (indlu yonke noma ukuhweba isicelo).
Ukufaka isistimu yokuhlunga nge-ultrafiltration ngaphandle kolwelwesi oluguquguqukayo, vele uxhume isistimu kulayini wokuphakelayo kanye nompompi ozinikele (amanzi aphuzwayo) noma ulayini wokuphakelwa kwempahla (zonke izinhlelo zokusebenza zokuhlala noma ezohwebo).
Iyiphi engcono, i-RO noma i-UF?
I-Reverse osmosis kanye ne-ultrafiltration yizinhlelo ezisebenza kahle nezinamandla ezitholakalayo. Ekugcineni, yikuphi okungcono ukukhetha komuntu siqu ngokusekelwe ezimweni zakho zamanzi, izintandokazi zokunambitheka, isikhala, isifiso sokulondoloza amanzi, ukucindezela kwamanzi, njll.
KukhonaI-RO yokuhlanza amanzifuthiIsihlanzi samanzi se-UFngokukhetha kwakho.
