Munguva yekushanda kweinjini, marara esimbi, guruva, kabhoni inoiswa oxidized pakupisa kwakanyanya, colloidal sediment, uye mvura inoramba ichipinda mumafuta ekuzora. Basa refirita remafuta nderokubvisa aya ma mechanical tsvina uye colloidal zvinhu, kuchengetedza mafuta ekuzora akachena nekuwedzera hupenyu hwayo hwesevhisi. Sefa yemafuta inofanirwa kunge iine simba rekusefa, yakaderera kuyerera, uye hupenyu hurefu hwesevhisi. Sitimu yekuzora mafuta inoshandisa masefa akati wandei ekusefa kwakasiyana{3}}kuunganidza mafirita, mafirita akakoshera, nemasefa akanaka-akabatana akatevedzana kana munhevedzano mudura guru reoiri. (Masefa akabatanidzwa munhevedzano negarari huru yeoiri anonzi akazara-masefa ekuyerera, ayo mafuta ekuzora ose anopfuura panguva yekushanda kweinjini; mafirita akabatana akatevedzana anonzi kupatsanurwa{7}}masefa ekuyerera.) Sefa yakakora yakabatanidzwa munhevedzano negarari huru yeoiri izere-sefa yekuyerera; sefa yakanaka yakabatanidzwa mukufambirana negarari huru yeoiri ikupatsanura-sefa yekuyerera. Mota dzemotokari dzemazuvano dzinowanzova nesefa yekuunganidzira uye imwe yakazara{12}}sefa yemafuta ekuyerera. Iyo coarse sefa inobvisa tsvina ine chidimbu saizi ye 0.05mm kana kupfuura muoiri yeinjini, nepo iyo yakanaka sefa inoshandiswa kubvisa tsvina yakatsetseka nehukuru hwe 0.001mm kana kupfuura.
