From Chlorination of Water by Joseph Race, 1918.
#Spacechem chlorination manual
Manual Control Chlorinator for the liquefaction of chlorine for water purification, early 20th century. The chlorination of the water supply helped stop the epidemic and as a precaution, the chlorination was continued until 1911 when a new water supply was commissioned. This was not simply modern calcium chloride, but contained chlorine gas dissolved in lime-water (dilute calcium hydroxide) to form calcium hypochlorite (chlorinated lime). His installation fed a concentrated solution of so-called chloride of lime to the water being treated. Alexander Cruickshank Houston used chlorination of the water to stop the epidemic. Permanent water chlorination began in 1905, when a faulty slow sand filter and a contaminated water supply caused a serious typhoid fever epidemic in Lincoln, England. In 1897 the town of Maidstone, England was the first to have its entire water supply treated with chlorine. Early attempts at implementing water chlorination at a water treatment plant were made in 1893 in Hamburg, Germany. Two other authorities endorsed this proposal and published it in many other papers in 1895.
In a paper published in 1894, it was formally proposed to add chlorine to water to render it "germ-free".
