DECEMBER MEETING OF NEW ENGLAND WATER WORKS ASSOCIATION
The December meeting of the association was held at Boston on Wednesday, the 13th instant. The executive committee met at the headquarters, Tremont Temple, at 11 a. m., and at 1 o’clock lunch was served at the Hotel Brunswick, following which the regular program was taken up. The secretary read the following applications for election to active membership: Thorndike Saville, R. H. Ellis, C. L. Crozier, E. H. Riggs and Joseph Mendies. By unanimous vote they were elected. Richard K. Hale, editor of the journal of the association, called the attention of the members to a geological survey paper on Massachusetts water sources, just issued, which gives the flow of all rivers and a number of small streams in the state of Massachusetts. In the opinion of Mr. Hale, it would be a very valuable addition to the library of any water works man. The publication is for distribution by Mr. C. H. Pierce, the Custom House Building, Boston, Mass. The bulletin is known as No. 415 of the water supply papers of the U. S. Geological Survey. Chas. H. Eglee, of Brookline, Mass., delivered a short talk on the prospects of a European peace at the present time after which a paper on “The Nature of Color in Water,” by Thorndike Saville, professor of sanitary engineering, Harvard University, was read. It dealt particularly with the colloidal theory of color suspension in water. He pointed out that heretofore the color in water has been placed to cither one of two conditions. First, colored matter in suspension, which would eventually precipitate itself out, and second, coloring matter dissolved in the water. Tests on two different types of water were carried out by Mr. Saville under the direction of Professor George C. Whipple. The first sample was taken from a swamp. It was high in alkaline and iron content. Experiments convinced Mr. Saville that the color in water, according to the colloidal theory which holds that coloring matter is composed of minute particles in suspension, and which will never settle, owing to their minuteness or physical properties, has cither a positive or a negative electrical charge. By placing a sample of this water in a large U-tube and passing an electrical currpnt through it, the negatively changed colored particles pass through the construction to the positive pole. In other words, in the samples of water where the colored matter was negatively changed, the color in the water was transferred to the branch containing the positive pole, where some of the matter was precipitated. The second sample of water was taken from Marlboro, Mass. It possessed acid characteristics. Mr. Saville mentioned that if an acid, hydrochloric for instance, is added to water, the color particles are made positive electrically no matter what their original condition. In this case when an electrical current is passed through the U-tube sample, the color matter passes through to the negative pole, leaving the positive side clear and the other branch containing all of the color. He pointed out the three general methods of decolorization at present employed commercially, and concluded by stating that it was his hope that through experiments now being carried out at to the clarification of water, that a process could be devised whereby the color may be removed without the use of chemicals. Mr. George C. Whipple expressed his appreciation of the careful work which Mr. Saville had done in the preparation of the paper. “This paper,” said Mr. Whipple, “is merely a preliminary contribution. We want to decolorize water without the use of chemicals, if possible. At the present time the use of chemicals for water purification is really the only satisfactory method. If we can accomplish this end we will feel that our work has been well worth while.” Mr. George A. Johnson said he would like to know in what manner this method of removal of color could be applied to commercial decolorization of water, and added, “it would be very interesting to me if an indication could be given to-day as to how this method could be used in practice and as to its cost and efficiency.” Francis L. Longley spoke on data he had compiled relative to the coloring matter of water, showing three sets of curves which proved interesting. Mr. Robert Spurr Weston gave an interesting account of Cuba. Mr. Weston illustrated with lantern slides. He described the sanitary conditions of both city and rural life of that country observed on four different occasions when he visited the West Indies. Commissioner James E. Donnelly, of Lowell, entertained the members with some humorous songs, which were greatly appreciated. The attendance, which was one of the largest seen at the monthly meetings of the association, was as follows:
