Taimakon tace diatomite ya fi kama tarko da ƙaƙƙarfan barbashi na ƙazanta da aka dakatar a cikin ruwa a saman da tashar matsakaici ta hanyar ayyuka guda uku masu zuwa, don cimma manufar rabuwar ruwa mai ƙarfi:

1. Sieving Effect Wannan sakamako ne na tacewa. Lokacin da ruwa ke gudana ta cikin ƙasa diatomaceous, ramukan ƙasan diatomaceous sun fi ƙanƙanta girman barbashi na ƙazanta, don haka ƙwayoyin ƙazanta ba za su iya wucewa ba kuma suna kama su. Ana kiran wannan tasirin Don tasirin nunawa. A haƙiƙa, ana iya ɗaukar saman kek ɗin tace a matsayin saman sikeli tare da matsakaicin matsakaicin pore daidai. Lokacin da diamita na ƙaƙƙarfan ɓangarorin bai kasance ƙasa da (ko ɗan ƙasa da ƙasa) diamita na pores na diatomite ba, ƙaƙƙarfan ɓangarorin za su "za a cire su daga dakatarwa". Ware waje, kunna aikin tacewa saman.

2. Tasiri mai zurfi Tasiri mai zurfi shine tasirin riƙewa na zurfin tacewa. A cikin zurfin tacewa, tsarin rabuwa yana faruwa ne kawai a cikin "ciki" na matsakaici. Wani ɓangarorin ƙazamin ƙazanta waɗanda ke ratsa saman kek ɗin tace suna toshewa ta hanyar tashoshi masu ƙarfi a cikin ƙasan diatomaceous da ƙananan pores a cikin kek ɗin tace. Irin wannan barbashi sau da yawa sun fi ƙanƙanta fiye da micropores na duniya diatomaceous. Lokacin da barbashi suka buga bangon tashar, za su iya barin ruwa ya kwarara. Duk da haka, ko zai iya kaiwa wannan matsayi ya dogara da ƙarfin da ba zai iya aiki ba da kuma juriya na barbashi. Ma'auni, irin wannan tsangwama da nunawa suna kama da yanayi, duka biyu na aikin injiniya ne. Ƙarfin tace ƙaƙƙarfan ɓangarorin yana da alaƙa da alaƙa kawai da girman dangi da siffa na tsayayyen barbashi da pores.

3. Adsorption Adsorption ya bambanta sosai da na'urorin tacewa guda biyu na sama. A haƙiƙa, ana iya ɗaukar wannan tasirin azaman jan hankali na electrokinetic, wanda galibi ya dogara ne akan kaddarorin fassarori masu ƙarfi da ƙasan diatomaceous kanta. Lokacin da waɗancan barbashi masu ƙananan pores a cikin ƙasan diatomaceous suka yi karo a saman ciki na ƙasan diatomaceous mai ƙuri'a, ana jan hankalin su da akasin zargin. Akwai kuma wani nau'i na sha'awar juna tsakanin barbashi don samar da gungu da kuma manne da duniya diatomaceous. Dukansu suna cikin talla, kuma tallan ya fi rikitarwa fiye da na baya biyu. An yi imani da cewa dalilin da ya sa ƙwararrun ƙwayoyin da suka fi ƙanƙara fiye da diamita na pore suna kama da su shine yawanci saboda: (1) Ƙungiyoyin intermolecular (wanda ake kira van der Waals jan hankali), ciki har da dipoles Effect, haifar da tasirin dipole da tasirin dipole nan take; (2) kasancewar yiwuwar Zeta; (3) tsarin musayar ion

Daga sama uku ayyuka, a cikin net matsa lamba tacewa tsari na dakatarwa, da sako-sako da granular diatomite tace taimako da ake amfani da matsayin tace matsakaici, wanda shi ne yafi don samar da yawa pores kamar yadda zai yiwu ga tace matsakaici Layer, da tace cake, da kuma samar da Spacer Layer na pores damar da dakatar da wuce ta cikin kananan pores na shãmaki Layer, da kuma ruwa da aka dakatar a kan m surface na ruwa, da kuma dakatar da ruwa a kan m surface. don haka da ƙarfi da ruwa sun rabu.
