Cov dej ntshiab yog hais txog H2O yam tsis muaj impurities, uas yog dej ntshiab lossis dej ntshiab rau luv luv.Nws yog dej ntshiab thiab huv tsis muaj impurities lossis kab mob.Nws yog tsim los ntawm cov dej uas ua tau raws li cov qauv kev huv ntawm cov dej haus hauv tsev los ntawm cov txheej txheem electrodialyzer raw, ion exchanger method, rov qab osmosis method, distillation method, thiab lwm yam tsim nyog ua.Koj tuaj yeem haus dej ncaj qha.
Nyob rau hauv xyoo tas los no, nrog kev txhim kho txuas ntxiv ntawm tib neeg cov kev coj noj coj ua, kev ua neej nyob, thiab qib kev noj qab haus huv, tib neeg tau hloov pauv los ntawm cov kev cai ua neej nyob xws li zaub mov thiab khaub ncaws mus rau kev nrhiav cov khoom noj thiab kev noj qab haus huv thiab kev ua neej.Rau cov dej haus indispensable nyob rau hauv tib neeg lub neej, kev ua tau zoo yog tshwj xeeb tshaj yog pom tseeb.Tam sim no, kev lag luam feem ntawm cov dej haus hauv kev lag luam khoom noj thiab dej haus tau mus txog 40%.Ntawm lawv, purified dej account rau ntau tshaj 1/3.Yog li ntawd, tag nrho cov txheej txheem ntawm kev tsim cov dej ntshiab huv yuav tsum tau saib xyuas thiab saib xyuas hauv lub sijhawm tiag tiag txhawm rau kom ntseeg tau tias cov dej ntshiab uas muab tso rau hauv kev ua lag luam yog cov khoom ntshiab, huv si thiab tsim nyog uas ua raws li cov cai thiab cov cai.
Vim tias qhov dej tsis zoo ntawm cov dej ntshiab, cov pa electromagnetic flowmeters tsis tuaj yeem ntsuas.
Ntxiv nrog rau cov khoom siv electromagnetic flowmeters, Sinomeasure tuaj yeem muab clamp-mounted turbine flowmeters lossis ultrasonic flowmeters tsis muaj cov yeeb nkab tawg raws li cov neeg siv khoom xav tau rau kev ntsuas dej ntshiab.
