Umahluko phakathi kwezixhobo ze-ultrafiltration kunye nezixhobo zokubuyisela umva i-osmosis

Umahluko omkhulu phakathi kwe-membrane ye-ultrafiltration kunye ne-osmosis eguqukayo ngumahluko kubukhulu be-pore. Ubungakanani bepore yenqanawa ye-reverse osmosis inwebu yipesenti enye ye-ultrafiltration membrane, kwaye ukuchaneka kokucocwa kwe-reverse osmosis inwebu iphezulu kunaleyo ye-ultrafiltration membrane. I-membrane ye-Ultrafiltration xa kuthelekiswa ne-reverse osmosis membrane, i-reverse osmosis membrane aperture incinci kakhulu kune-ultrafiltration membrane, i-reverse osmosis membrane aperture yi-0.0001 micron, i-ultrafiltration membrane aperture yi-0.001 micron. Ubungakanani bepore bereverse osmosis inwebu yipesenti enye ye ultrafiltration inwebu, ngoko ke amanzi ahluzwe yi reverse osmosis inwebu acwenge ngakumbi kunaleyo ye ultrafiltration membrane.

I-membrane ye-Ultrafiltration yindlela yokwahlula i-membrane apho i-membrane ine-porous asymmetric structure. Inkqubo yokuhluza yinkqubo yokwahlukana kwesisombululo esekelwe kumgaqo-siseko we-mechanical sieving yokwahlukana koxinzelelo phakathi kwamacala amabini e-membrane, uxinzelelo olusebenzayo luhlala luyi-0.01 ukuya kwi-0.03Mpa, kunye nobukhulu be-pore obuhle be-membrane ye-ultrafiltration malunga ne-0.001 ukuya kwi-0.01 microns. Ubunzima bemolekyuli ye-interception yi-1,000-500,000 daltons, ngoko ke inkqubo yokwahlula i-membrane ye-ultrafiltration yayikhe yajongwa njengenkqubo yokwahlula ngokwasemzimbeni.

I-Reverse Osmosis inwebu yinwebu eyenziweyo ekwaziyo ukungena ngaphakathi eneempawu ezithile ezidalwe ngokulinganisa inwebu yebhayoloji ekwaziyo ukungena ngaphakathi. I-RO sisishunqulelo sesiNgesi se-reverse osmosis membrane, isiTshayina yintsingiselo ye-osmosis ebuyela umva. Ukuhamba kwamanzi ngokupheleleyo ukusuka phantsi ukuya phezulu. Xa amanzi ecinezelekile, amanzi aya kuhamba ukusuka phezulu ukuya phantsi. Oku kubizwa ngokuba ngumgaqo we- reverse osmosis. Umngxuma wokuvula inwebu ye-osmosis umva zizigidi ezihlanu (0.0001 micron) zoboya bomntu. Iintsholongwane kunye neentsholongwane zingama-5,000 amaxesha amakhulu, zivumela kuphela iimolekyuli zamanzi kunye nezinye ii-ion zeminerali eziluncedo ukuba zidlule, ngelixa ezinye izinto ezingcolileyo kunye neentsimbi ezinzima zikhutshwa kwimibhobho yamanzi amdaka.

I-aperture ye-reverse osmosis membrane yi-1/100 ye-aperture ye-ultrafiltration membrane, kunye nokuchaneka kokucoca kwe-RO reverse osmosis membrane ifikelela kwi-0.0001 micron. Nangona kunjalo, ukuchaneka kokucoca kwe-membrane ye-ultrafiltration yi-0.001 microns. Ke ngoko, iimembrane ze-osmosis ezibuyisela umva zinokususa isinyithi esinzima, i-pesticides, i-chloroform kunye nezinye izinto ezingcolisa iikhemikhali emanzini, kodwa iimbumba ze-ultrafiltration azikwazi. I-membrane ye-ultrafiltration isusa izinto ezingcolisayo kunye neebhaktheriya, kwaye i-osmosis eguquguqukayo ibasusa ngamandla onke.
