Diatomaceous lub ntiaj teb lim yog hais txog cov txheej lim dej nrog diatomaceous lub ntiaj teb txheej raws li cov txheej txheem pom, feem ntau yog siv cov tshuab sieving los daws cov txheej txheem dej lim dej uas muaj cov teeb meem me me. Diatomaceous lub ntiaj teb lim lim dej cawv thiab dej haus tsis hloov pauv, tsis muaj tshuaj lom, tsis muaj cov khib nyiab pov tseg thiab sediments, thiab yog cov ntshiab thiab pob tshab. Cov lim dej diatomite muaj qhov pom tseeb siab, uas tuaj yeem ncav cuag 1-2 microns, tuaj yeem lim tawm Escherichia coli thiab algae, thiab cov turbidity ntawm cov dej lim yog 0.5 txog 1 degree. Cov khoom siv npog thaj tsam me me, qhov siab qis ntawm cov khoom siv, qhov ntim tsuas yog sib npaug rau 1/3 ntawm cov xuab zeb lim, tuaj yeem txuag tau feem ntau ntawm kev nqis peev hauv kev tsim kho pej xeem ntawm chav tshuab; ntev kev pab cuam lub neej thiab siab corrosion kuj ntawm lim ntsiab.
