各位大人:
以下推論是否有誤
400 liter water x 400 dppm = 160 g Ca.
however, 1 liter 石灰水只有一點點 Ca (1 liter water 只能溶1.5 g Ca(oh)2) : => 1.5 g x 40/74 = 0.81 gram Ca (74 為 Ca(oh)2 之分子量.
If we cosume 160 g Ca say 25% a month; that is 160 x 25% = 40 g;
then we need around 50 liter 石灰水 (50* .81 =40) ; to replenish 40 g Ca we lose in a month; is that right?
謝謝
