Cov txheej txheem ua npuas dej hlau yuav tsim qee cov khoom pov tseg, xws li cov chips hlau, cov pa khib nyiab, dej khib nyiab, kua khib nyiab, thiab lwm yam. Cov khib nyiab no yuav tsum tau kho kom zoo thiab rov ua dua tshiab kom txo tau qhov cuam tshuam rau ib puag ncig.
Rau cov hlau shavings, nws tuaj yeem siv tau thiab rov siv dua los ntawm kev rov ua dua tshiab rau hauv cov ntaub ntawv raw rau rov siv dua. Rau cov pa khib nyiab thiab dej khib nyiab, cov txheej txheem tswj cov pa phem, xws li adsorption, oxidation, nag lossis daus, filtration, thiab lwm yam, tuaj yeem siv los tshem tawm cov pa phem nyob rau hauv lossis txo cov emission concentration ua ntej tso tawm lossis kho ntxiv. Rau cov kua khib nyiab, lawv tuaj yeem kho tau los ntawm evaporation, concentration, crystallization, thiab lwm yam, kom rov ua dua thiab siv cov khoom muaj txiaj ntsig hauv lawv, thiab tib lub sijhawm txo cov emission ntawm pov tseg.

Tsis tas li ntawd, cov ntaub ntawv thiab cov tshuaj siv hauv cov txheej txheem ua npuas hlau yuav tsum tau txheeb xyuas, khaws cia, kho thiab rov ua dua kom txo tau qhov cuam tshuam rau ib puag ncig. Rau cov khib nyiab uas tsis tuaj yeem rov ua dua tshiab, muaj kev nyab xeeb thiab siv tau zoo, xws li kev siv hluav taws xob thiab kev pov tseg, yuav tsum tau txais kev pom zoo kom txo qis qhov cuam tshuam rau ib puag ncig.
Hauv kev xaus, kev kho kom tsim nyog thiab rov ua dua tshiab ntawm cov khoom pov tseg hauv cov txheej txheem ua npuas dej yog qhov tsim nyog los txo qhov cuam tshuam rau ib puag ncig thiab ua tiav lub hom phiaj ntawm kev txhim kho kom ruaj khov.
