Ultra-kuyungurura (UF) ni tekinike yo gutandukanya membrane isukura kandi itandukanya ibisubizo.Kurwanya umwanda PVDF ultrafiltration membrane ikoresha polymer material polyvinylidene fluoride nkibikoresho nyamukuru bya firime yibanze, membrane ya PVDF ubwayo ifite imbaraga zo kurwanya okiside, nyuma yo guhindura ibintu bidasanzwe kandi ikagira hydrophilique nziza, mugikorwa cya membrane hifashishijwe igishushanyo mbonera cya micropore no kugenzura imiterere ya micropore, micropore ingano ya pore igera kurwego rwa ultrafiltration.Ubu bwoko bwibicuruzwa bifite ibyiza bya pore imwe, kuyungurura neza, kwinjiza amazi menshi kuri buri gace, kurwanya okiside nimbaraga nyinshi.
