The precipitates being settled out of the water, the result-ing pure water is used for boiler feed. It is evident that to workthis purification process the analysis of the water must be knownso that the right amount of quicklime and soda solution can beused to completely precipitate the scale-producing salts withoutwasting lime or soda. Once these proportions are fixed by theanalysis of the water, the whole problem lies in the apparatus formixing the precipitating solutions and separating the precipi-tates. It is not desirable to have an expert chemist in chargeof every steam plant to supervise the water purification. It is, onthe other hand, desirable to have a water purification apparatus sosimple that it will require practically no
