3. Kev soj ntsuam
Tom qab cov kais dej boiled, phenomena xws li nag lossis daus dawb, turbidity, dawb ntab teeb meem thiab scaling yuav tshwm.Vim tias cov dej ntuj feem ntau muaj qhov tawv, nws cov khoom tseem ceeb yog calcium thiab magnesium.Tom qab cua sov, nws ua ke nrog cov bicarbonate tam sim no nyob rau hauv dej los tsim ib tug dawb precipitate ntawm calcium carbonate thiab magnesium hydroxide uas yog insoluble nyob rau hauv dej.Qhov no yog ib txwm tshwm sim.Txhua yam dej ntuj muaj ntau dua lossis tsawg dua, thiab cov dej nag dawb yuav raug tsim tom qab cua sov.Tsuav nws tsis cuam tshuam rau kev haus ib txwm, tsis txhob ntshai.
