Kuwedzera diatomite mafirita aid panguva yekusefa kwakafanana nekutangisa. Iyo diatomite inotanga kusanganiswa mukumiswa kweimwe concentration (kazhinji 1∶8 ~ 1∶10) mutangi rekuvhenganisa, uyezve kuturika kunopombwa mupombi huru yemvura zvinoenderana neimwe sitiroko nepombi yekuisa mita yosanganiswa zvakaenzana nemvura yetitanium inofanira kusefa isati yapinda muchina wekusefa. Nenzira iyi, iyo yakawedzerwa diatomite sefa yerubatsiro inosanganiswa zvakaenzana neyakamiswa yakasimba uye colloidal tsvina musefa titanium mhinduro uye yakaiswa pamusoro pekunze kweiyo precoating kana sefa keke, ichienderera ichigadzira nyowani sefa layer, kuitira kuti keke resefa rinogara richichengeta kuita kwakanaka kwekusefa. Iyo itsva sefa layer haingogone kubata zvakamiswa zvinyoro uye colloidal tsvina mutitanium fluid, asi zvakare inobvumira iyo yakajeka mvura kuti ipfuure nepalabyrinth yemicroporous chiteshi, kuitira kuti kusefa kuitwe zvakanaka. Huwandu hwediatomite sefa yerubatsiro zvinoenderana nehuturu hwetitanium mhinduro inofanira kusefa. Iyo turbidity yemabheji akasiyana etitanium yemvura yakasiyana, uye turbidity yekumusoro uye yepasi zvikamu zvetitanium yemvura mutangi rimwe chete zvakasiyana. Naizvozvo, sitiroko yepombi yemamita inofanirwa kuve yakachinjika, uye huwandu hwediatomite sefa yekubatsira inofanira kugadziridzwa.
Zvidzidzo zvakaratidza kuti huwandu hwakasiyana hwediatomite sefa yerubatsiro ine simba guru pakuwedzera chiyero chekudzvanywa uye kureba kwese kwesefa kutenderera kweiyo yakafanana titanium fluid filtration. Kana huwandu husina kukwana, kudonha kwekumanikidza kunowedzera nekukurumidza kubva pakutanga, kupfupisa zvakanyanya kutenderera kwefiltration. Kana huwandu hwekuwedzera hwakawandisa, pakutanga kwekumanikidza kudonha kwekuwedzera kumhanya kunononoka, asi gare gare nekuti iyo sefa yerubatsiro yakakurumidza kuzadza kamuri yekusefa yemuchina wekusefa, hapana nzvimbo yekugadzika maodhi matsva, kudonha kwekudzvanywa kwakakurumidza kuwedzera, kuyerera kwakadzikira zvakanyanya, kumanikidza kudzvanywa kwesefa kumisa, kuitira kuti kutenderera kwesefa kupfupike. Iyo yakareba yefiltration cycle uye yakawanda yekusefa goho inogona kuwanikwa chete kana iyo yekuwedzera huwandu hwakakodzera, kudonha kwekumanikidza kunokwira pamwero wepakati uye iyo sefa cavity inozadzwa pamwero wepakati. Iyo yakanyanya kufanirwa huwandu hwekuwedzera inopfupikiswa kuburikidza neiyo mamiriro bvunzo mune yekugadzira maitiro, haigone kuve yakajairwa.
Pasi pemamiriro akafanana ekusefa, kushandiswa kwediatomite sefa yekubatsira kunodzikiswa zvakanyanya kupfuura iyo yemarasha poda sefa yekubatsira, uye mutengo unodzikiswa. Kushandisa diatomite pachinzvimbo chehupfu hwemarasha kunobatsira kushandisa hupfumi hwediatomite zviwanikwa muChina, kuchengetedza zviwanikwa zvesango zvishoma, uye kuona kubatana kwakabatana kwekusimudzira hupfumi uye kuchengetedza kwezvakatipoteredza.
