Description
Excerpt from Water Softening and Purification: The Softening and Clarification of Hard and Dirty Waters
Rain water and distilled water being unavail able, manufacturers have to depend either upon the town supply or upon the water which they can draw from springs, wells or streams. Such waters are generally what is called hard.
Hard water contains in solution the bicarbonates, sulphates, chlorides or nitrates of lime and magnesia. The bicarbonate of iron, alumina and silica are also generally present in natural waters, but seldom in such proportion as to be of practical importance, rarely, in fact, amounting together to more than one grain per gallon.
