纯化水的净化
科罗拉多州普韦布洛（Pueblo）的供水净化2号是Pueblo“ Journal”的审查的主题，该地区是由该地区董事会准备的。它指出，董事会很早就确信，目前，供应与阿肯色河息息相关，并立即着手给人民提供最好的水。瓦格纳（Wagner）警长于1911年春季被派往东方，以调查净水系统，并获得了许多有价值的信息，董事会确定，应保留的每一美元在支付维护和运营费用之后，应用于使水更好。由于资金有限，进度很慢，但是随着结果开始表明，赞扬消费者的赞扬和鼓励感到非常满意和鼓励。相对于“期刊”采用的待遇，阿肯色河是从许多支流中喂养的，在洪水季节中降落了与饲养者一样多种水，带来了不同的问题。治疗的成功取决于负责人的警惕和智慧以及观察变化和转移混合物以满足条件的能力。有时候，水的物质无意义地用于凝血过程并导致云层成品，并且通常，原水的浊度越大，细菌去除量就越大。简而言之，这通常称为石灰和铁处理。直到今年年初硬度为50％，仍然可能存在5％的污染，可能携带伤寒和其他致命的细菌。 So the present board again sent its superintendent East in search of further knowledge, and the result is the installation of a sterilization plant. The liquid chlorine process was selected. Now a chemical and bacteriological examination is made daily. Since the installation of a laboratory it has been made evident that this equipment was essential to the successful treatment of the W'ater, effecting saving and material and furnishing a definite record of results obtained. Examinations for one month give no indication of dangerous contamination. A report dated July 7 and signed C. W. Maynard, city bacteriologist, said: Average per cent, bacterial removal, 99.2 per cent.
Bacteria, per ccm . 7
