SOFTENING WATER. 



'N our last number (p. 179) we described an apparatus 

 made by the Stanhope Company for softening water 



portion of the chemical re-agents (soda and lime-water) 

 being admitted at the same time. The mixture in the pipe 

 then enters the bottom of one of the clarifying vessels, the 

 other being merely a duplicate, and having precisely similar

by means of soda and lime. The accompanying illustration 

 shows an apparatus identically the same in principle, but 

 of a larger size, there being two clarifying vessels instead of 

 one. As already mentioned, the water to be softened enters 

 the large external pipe shown in the figure, a proper pro- 



connections. The water in the clarifying vessels rises 

 slowly, and the precipitates formed are deposited on the 

 inclined trays shown in dotted lines. When the water 

 reaches the top of the vessels it is quite clear and fit for 

 use.
