Depth Filtering Thiab Deg Filtering

Kev xaiv cov khoom lim yog qhov tseem ceeb los xyuas kom meej qhov tsim nyog ntawm cov lim xov xwm thiab kev xaiv zoo tshaj plaws ntawm cov khoom tsim nyog thiab lim cov qauv tsim rau txhua daim ntawv thov pom. Ob txoj kev lim dej tseem ceeb, kev lim dej tob thiab qhov chaw lim dej. Nyob rau hauv cov ntaub ntawv ntawm qhov tob filtration, hais yog daig nyob rau hauv lub filtering media; nyob rau hauv deg filtration lawv yog khaws cia rau tom qab tsim nto.

Surface filtration yog feem ntau filtering thiab sieving mechanism nyob rau hauv uas hais tias loj tshaj qhov pore loj ntawm lub lim tawm yog sib cais. Lawv qhov luaj li cas tiv thaiv lawv los ntawm kev nkag los yog dhau los ntawm cov lim pores. Cov khoom tom qab sib sau ua ke rau ntawm qhov chaw, uas nce hauv cov tuab raws li cov kua dej ntau ntxiv raug yuam mus rau hauv cov xov xwm lim. Vim lawv cov qauv pore me me, lim discs tuaj yeem pab cais cov khoom me me. Nws cov txheej txheem tuaj yeem khiav tsis tu ncua / nce siab lossis tsis tu ncua / txo qis. Txij li feem ntau cov ntxaij lim dej saum npoo tsis zoo sib xws hauv smoothness lossis pore qauv yuav cuam tshuam rau lub neej lim, ces qhov tob lim yog lwm qhov kev xaiv los xav txog thaum siv.

Qhov tob pom feem ntau yog siv rau hauv cov ntawv thov uas cov khoom me me yuav tsum tau sib cais. Piv txwv li, tiv thaiv cov cuab yeej los ntawm fouling los yog corrosion, tiv thaiv catalysts los ntawm lom, thiab purification. Cov khoom nkag mus rau hauv cov xov xwm lim dej, thiab cov lim dej ntau txheej txheej tuab tiv thaiv kev txhaws ntxov ntxov ntawm lub lim dej thiab ua kom cov av khaws cia thiab kev pabcuam lub neej. Raws li cov khoom raug kaw nyob rau hauv qhov tob ntawm cov xov xwm, lim cov khoom yuav tsum tau ntxuav. Kev ntxuav tuaj yeem ua tiav nrog cov kuab tshuaj, ultrasonic kev co, pyrolysis, chav ntxuav lossis siab siab rov qab ntxuav.
