I-Ultrafiltration iteknoloji yokwahlula i-membrane enokuthi ihlambuluke kwaye ihlukanise isisombululo.Inkqubo ye-membrane ye-Ultrafiltration sisixhobo sokwahlula isisombululo kunye ne-ultrafiltration membrane yesilika njengesixhobo sokucoca kunye nokwahlukana koxinzelelo kumacala omabini e-membrane njengamandla okuqhuba.I-ultrafiltration inwebu ivumela kuphela isinyibilikisi (njengeemolekyuli zamanzi), iityuwa ezingaphiliyo kunye nezinto eziphilayo ezincinci zemolekyuli kwisisombululo sokudlula, kwaye ibamba izinto ze-macromolecular ezifana nezinto eziqinileyo, i-colloids, iiprotheni kunye ne-microorganisms kwisisombululo, ukuze kuphunyezwe. injongo yokuhlanjululwa okanye ukwahlukana.
