Darajar ƙuntatawa (SDI), wanda aka fi sani da darajar FI (Fouling Index), yana daya daga cikin mahimman sigogin nuna ingancin ruwa. Yana nuna yawan ƙwayoyin ruwa, colloids da sauran abubuwa da za su iya toshe kayan aikin tsabtace ruwa daban-daban. Ta hanyar auna darajar SDI, za a iya zaɓar fasahar tsarkakewar ruwa ko kayan aiki masu dacewa. Dangane da hanyar ASTM 4189-95, an san wannan hanyar a cikin masana'antu.

A lokacin sarrafa ruwa na reverse osmosis, ƙimar SDI tana daya daga cikin mahimman alamun auna ruwan da ke cikin tsarin reverse osmosis; Yana da babban hanyar bincika ko pre-treatment tsarin fitarwa ya kai reverse osmosis shiga ruwa bukatun. Girmansa yana da mahimmanci ga rayuwar tsarin reverse osmosis.

SDI darajar ne ya auna rage gudun gudun da membrane ta 47mm diamita, 0.45μm aperture. Dalilin da ya sa za a zabi wani membrane da 0.45μm bore, saboda a karkashin wannan bore, colloidal abubuwa ne mafi sauki blocking membrane fiye da wuya granules (kamar yashi, sandstone, da dai sauransu).

Ana canza raguwar gudun gudun zuwa darajar da ke tsakanin 1 zuwa 100, watau darajar SDI. Da ƙananan darajar SDI, ƙananan yanayin toshewar gurɓataccen ruwa ga membrane. Daga la'akari da tattalin arziki da inganci, mafi yawan reverse osmosis masana'antun shawarar reverse osmosis shigar da ruwa SDI darajar ba sama da 5.

Millipore ® SDI gauge tsarin ya haɗa da wani matsin lamba saukewa bawul, 47mm canji film-type tace, membrane zane-zane da wasu da ake bukata bawul, haɗi bututu da kuma haɗi sassa. Wannan tsarin ya ƙunshi akwatin cakuda cellulose tacewa fim, cikakken dacewa da bukatun hanyar ASTM. Ta amfani da wannan na'urar, za a iya auna darajar SDI ta yanar gizo ta hanyar shirya kalibra da matattarar seconds kawai.
