1. Ifilimu ye-UF yenziwe ngee-membranes ze-ultrafiltration, ngelixa ifilimu ye-Ro yenziwe ngee-membranes ze-reverse osmosis.

2. Ifilimu ye-UF isetyenziselwa ukususa amasuntswana amakhulu kunye neemolekyuli, ngelixa ifilimu ye-Ro isetyenziselwa ukususa amasuntswana amancinci kunye neemolekyuli.
3. Ifilimu ye-UF inezinga eliphantsi lokungamkeleki kunefilimu ye-Ro, oko kuthetha ukuba ezinye izinto ezingcolisayo zisenokudlula kwifilimu ye-UF, ngelixa ifilimu ye-Ro inezinga eliphezulu lokungamkeleki.
4. Ifilimu ye-UF isetyenziswa kwizicelo zonyango lwamanzi ezifana nonyango lwangaphambi kokusetyenziswa kweenkqubo ze-RO, ngelixa ifilimu ye-Ro isetyenziswa kwizicelo zamanzi acocekileyo kakhulu.
5. Ifilimu ye-UF ifuna uxinzelelo oluncinci kunefilimu ye-Ro, nto leyo eyenza ukuba isebenzise amandla kakuhle.
6. Ifilimu ye-UF ixabisa kancinci kunefilimu ye-Ro, nto leyo eyenza ukuba ibe lukhetho oludumileyo kwiimveliso kunye nezicelo zonyango lwamanzi zikamasipala.
