Usage:
The pretreatment of water supplies involves the use lime to decrease the acidity, to soften, and to clear drinking water. It is used as an opacifier in plastics. The paper industrial uses it in pulping wood; because lime is highly alkaline, it dissolves the lignin that binds the fibers together in wood. In the refining of sugar, lime causes coagulation of plant material, allowing to be more easily separated from the sugar syrup。
