Lub luag haujlwm tseem ceeb thiab lub luag haujlwm ntawm cov tshuaj kho dej yog ua kom muaj kev nyab xeeb ntawm cov dej, txhim kho kev lag luam, ua kom cov khoom siv lub neej ntev, thiab txhawb kev rov ua dua tshiab thiab kev tiv thaiv ib puag ncig.
Ua kom cov dej zoo raws li cov qauv: Los ntawm flocculation, sedimentation, thiab sterilization, cov tshuaj kho dej tau zoo tshem tawm cov khib nyiab, organic teeb meem, cov hlau hnyav, thiab cov kab mob, kom ntseeg tau tias cov dej muaj dej, dej haus hauv nroog, thiab cov dej khib nyiab kho tau raws li lub teb chaws lossis kev lag luam tawm thiab siv cov qauv.
Tiv thaiv cov cuab yeej Corrosion thiab Scale: Corrosion inhibitors tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau, txo cov kav dej, boilers, cua kub exchangers, thiab lwm yam khoom siv; scale inhibitors inhibits cov deposition ntawm calcium carbonate, calcium sulfate, thiab lwm yam scale, tswj kom sov hloov efficiency thiab tiv thaiv cov khoom puas vim los ntawm blockage los yog overheating.
Txhim kho kev kho dej kom zoo: Flocculants (xws li polyaluminum chloride PAC thiab polyacrylamide PAM) tuaj yeem sib sau cov khoom me me mus rau hauv cov flocs loj, txhim kho sedimentation thiab pom ceev; coagulants thiab dispersants txhim khu kev ruaj ntseg thiab txo kev khiav hauj lwm lub zog noj.
Kev kho dej yog qhov tseem ceeb tshaj plaws rau kev txhim kho cov dej zoo, tiv thaiv scaling, corrosion, algae loj hlob thiab ib puag ncig muaj kuab paug, ua kom muaj txiaj ntsig zoo, nyab xeeb thiab ntev - lub sijhawm ua haujlwm ntawm kev tsim khoom, thiab txuag dej, zog, khoom siv thiab tiv thaiv ib puag ncig.
