Qhov zoo tshaj plaws yog: lub yeeb nkab uas zoo sib xws rau cov yeeb nkab hlau, yooj yim khoov, tsis muaj teeb meem, zoo heev ua rau kub, siab siab thiab corrosion kuj, tus hauv lub raj, me me tsis kam thiab tsis muaj txhaws. Cov nplaim nplaum zoo, hluav taws kub zoo thiab hluav taws kub.
Kev kub thiab kev txuag kev txuag kom zoo yog qhov zoo, nws yuav siv tau ntev ntev hauv 70 degrees C, thiab qhov kev kub ntxhov siab kub siab txog 95 degrees C, uas ua tau raws li qhov yuav tsum tau muaj ntawm cov cua sov hauv tsev.
Lub installation thiab kev txuas yog yooj yim thiab txhim khu kev qha. Cov yeeb nkab thiab cov yeeb nkab siv yog tsim los ntawm tib hom khoom siv, vim li ntawd cov cua kub zoo tshaj qhov qub vuam qhov kev ua haujlwm zoo thiab qhov kev ruaj ntseg hauv lub cev yog siab.
