Kev tsim cov dej ntxhia, dej caij nplooj ntoos hlav, lossis lwm yam kua tsis muaj menyuam.
Kev kho mob ntawm cov kais dej, dej saum npoo av, dej zoo thiab dej ntws.
Pretreatment ntawm RO.
Kev kho, rov siv dua thiab rov siv dua cov dej khib nyiab hauv kev lag luam.
Cov khoom no tau raug pov thawj tias muaj cov teebmeem hauv qab lim dej raws li kev pabcuam ntawm cov dej sib txawv:
Cov khoom xyaw | nyhuv |
