Diatomaceous ntiaj tebfiltration yog cov txheej txheem tseem ceeb hauv kev txhim khu kev qha thiab zoo ib yam ntawm cov roj zaub, roj noj, thiab lwm yam khoom noj khoom haus.

Diatomaceous ntiaj tebCov khoom siv lim dej yog lub teeb hauv qhov hnyav, tshuaj lom neeg tsis muaj zog, thiab tsim cov porosity siab lim ncuav qab zib kom tswj tau cov kua dej dawb.Tshwj xeeb, qhov kev pab lim dej tau zoo yog yam ntxwv los ntawm cov hauv qab no:

Cov qauv ntawm cov khoom yuav tsum yog xws li tias lawv yuav tsis ntim ua ke, tab sis yuav tsim cov khoom qab zib uas yog 85% mus rau 95% pore qhov chaw.Qhov no tsis tsuas yog tso cai rau tus nqi pib siab dua, tab sis kuj tseem muab qhov chaw pore rau ntxiab thiab muaj cov khib nyiab filterable thaum tawm hauv feem pua ​​​​ntawm cov channel qhib rau ntws.
