Yuav kom txuas lub neej ua haujlwm ntawm cov thawv hloov khoom siv tau ntev dua, yuav tsum tau ua peb yam: kev xaiv, kev siv cov lus qhia, thiab kev saib xyuas txhua hnub.
Thaum xaiv, yuav tsum xaiv cov khoom siv tsim nyog raws li qhov yuav tsum tau ua kom lub nra hnyav thiab qhov chaw siv. Rau kev lag luam zaub mov, cov khoom siv PP yog qhov tsim nyog; rau cov xwm txheej kev lag luam uas xav tau kev tiv thaiv kev cuam tshuam, cov khoom siv HDPE tuaj yeem xav txog. Qhov no zam kev puas tsuaj ua ntej lub sijhawm los ntawm kev tsis sib xws ntawm cov khoom siv thiab cov kev xav tau.
Thaum siv, yuav tsum ua raws li txoj cai ntawm "kev tuav nrog kev ceev faj". Qhov siab ntawm kev teeb tsa yuav tsum tsis txhob tshaj qhov txwv ntawm lub thawv kom tiv thaiv kev hloov pauv. Thaum thauj mus los, cov thawv yuav tsum tau kho nrog cov hlua khi kom tsis txhob muaj kev sib tsoo. Tib lub sijhawm, txwv tsis pub siv cov thawv tig rov qab hauv cov xwm txheej dhau ntawm qhov tsim, xws li tuav cov kua kub siab lossis cov hlau ntse.
Kev saib xyuas txhua hnub kuj tseem ceeb heev. Tom qab siv txhua zaus, cov seem hauv lub thawv yuav tsum tau ntxuav kom huv si kom tiv thaiv cov tshuaj corrosive kom tsis txhob lo rau ntev. Yog tias muaj qhov tawg me me hauv lub thawv, yuav tsum siv cov kua nplaum tshwj xeeb los kho; yog tias cov khoom siv puas lawm, cov khoom siv yuav tsum tau hloov pauv raws sijhawm. Thaum khaws cia, xaiv qhov chaw qhuav thiab muaj cua nkag, thiab tsis txhob raug tshav ntuj ncaj qha, nag, lossis daus.
Los ntawm kev tswj hwm kev tshawb fawb, lub neej ua haujlwm ntawm cov thawv hloov pauv ib txwm tuaj yeem ntev dua 30%, uas txo cov nqi thauj khoom.
