Allen, Director of Physical Education University of Kansas Lawrence, Kansas Dear Dr. Allen: Since talking to you over telephone last week, the U. S. Naval Air Base at Olathe, Kansas called for bids on some work in our line. The bids will be opened tomorrow and as I have handled the proposition so far, it is necess- ary for me to be at the Naval Base at that time. We have been working overtime to keep up with govern- ment orders, and most of our office engineers have had to go on the road. As I do not want to send any man to see you who is not capable of giving you the best recommendations, I prefer to handle the matter myself. As I see it now, I can be in Lawrence this coming Thursday afternoon, and if I do not hear from you and you do not hear from me meanwhile, you may depend upon me being there. I shall try to be in your office around 1:00 P.M. April 22nd. Regretting my inability to confer with you tomorrow, I remain, Sincerely yours, E.W.

Stoltenberg, Chemist LAWRENCE, KANSAS October 14, 1942 Dre Fe. C. Allen Director of Physical Education Robinson Gymnasium Campus Dear Dr. Allen: At the request of your department I made an inspection today of the swimming pool and of the filtration end purification equipment. The water in the pool was turbid and gave off a considerable odor. The odor can be described as a combination chlorine and mouldy odor. The odor is caused, I believe, by the organic matter present in the water. The increase in the number of persons using the pool has placed a load on the filtration equipment that it cannot treat the water properly under the present conditions of operation. Most of the analyses have shown this water to be of satisfactory bacteriological quality, but the physical quality of the water is poor. In order to improve the physical quality I am listing some suggestions below. Because of the limited capacity of the recirculating pump and the filter it may be necessary to drain the pool once each two or three weeks. The pump -now in use can recirculate ail of the water once each twenty-four hours if kept in operation continuously. The suggestions follow: (1) Drain the pool end start again with clean water. (2) Examine the filter to be sure that the ingredients are properly graded and the required depth. The gravel should be 18" deep and the sand 18" to 24" deep. The sand should have an effective size between 0.35 and 0.50 mm. and a uniformity coeffecient between 1.25 and 1.80. Sere Dre F. C. Allen page 2 October 14, 1942 (3) Feed alum into the recirculated water after each beckwashing of the filter. This is done so that the alum will react with the naturel alkalinity of the water to form a floc of aiuminum hydroxide over the top of the filter. The floc aids in taking the colloidal material and finely divided particles from the water. A pH between 7.2 and 7.6 should be maintained in order that the floc can form. One-haif pound of aium should be added to the solution pot when the filter is back- washed. Both the valve on the influent line and the valve on the effluent line should be opened after the alum hes been placed in the pot e (4) Operete the recirculation pump end chlorinator contimously. The rate of feed on the chlorinator will probably have to be adjusted, as little more chlorine will be required and the feeding period will be lengthened. The water in the pool should be filtered at least three times each day. The present capacity of the pump and the filter will not allow this, so it may be necessary to get lfarger units or drain the pool more frequently. (5) Every person entering the pool should take a shower with soap in order to carry as smail amount of organic matter into the pool as possible. The addition of liquid chlorine and a small amount of alum to the water will cause the pH to drop. This may be prevented by the addition of lime or soda ash. It is my suggestion that you obtain severel hundred pounds of soda ash to control the pH. This could be mixed in solution and fed at the solution pot each day. After the pool has been filled for two or three days with the city water, there will be a decided tendency for the pH to drop rapidly. This can be prevented only by careful pH control and the feeding of soda ash. If you will let me kmow when this stage is reached, I will try to help you get the feed adjusted. When the water has been brought beck to the pioper aikelinity, a feed of 1-1/2 pounds of soda ash per pound of chlorine is usually sufficient to hold the pH up. Residual chlorine tests should be made at least three times during the day and a record kept of the results. The residual shovld build up during the night and will drop again during the day. The chlorine re- Ssiduei should not be less than 0.3 pepem. or exceed 0.6 DeDeMe Very truly yours, DIVISION OF SANITATION : Dwight lp, Metzier DFii : dmb Assistant Engineer ccs; E.

Bulletin No. 626 EVERSON FILTER SERVICE COMPANY Everson Safety-Electric Sterelators os ch This De Luxe Cabinet Type Everson SAFETY ELECTRIC STERELATOR is a high development in swimming pool steriliz- ing equipment. By means of an elec- trolytic cell, it manufactures “Chlorine” in its perfect form—sodium hypochlor- ite (NaOCl), from ordinary rock salt and water. It eliminates the need for special vents, vaults, gas masks and the hazardous handling of high pres- sure chlorine gas drums and other ex- pensive precautionary equipment as is usually required with pressure type gas STERELATORS. Sodium hypochlorite is an exceedingly effective, non-irritating and stable germicide which pervades every corner of the pool. Output is set at any point by turning a (rheostat control) dial. Operating cost for average Indoor, or small Outdoor Pool is only a few cents per day. Installation is simple and cabinet requires only 20x40 in. of space. It can be located at any con- venient place (preferably above level of pool, between filters and inlets, or near : water re-circulating pump). Operates on 110 volts, 15 amperes, and %4-in. city water supply connection. Everson Filters For the clarification of water, Everson filter units, singly or in batteries, with complete operative and control fittings, are designed to more than fulfill the requirements of health codes and to give consistent performance during life of installation. Everson Rota-Meter Sterelators ss Everson Rota-Meter Chlorine Con- trol Apparatus embodies the most im- proved and practical features available for dispensation of chlorine gas and chemical reagents for swimming pool water purification. This STERELATOR, in either model shown, embodies an ac- curate, foolproof, visible, metering de- vice, rendering readings within 1% and giving Everson the highest degree of accuracy in the chlorinating field. Thorough and accurate mixing facili- ties, automatic venting, automatic syphon break which prevents back flooding, and simplicity of operation are other outstanding features. Auto- matic gas and water shut-off may be had on specification. EversoN STERELATORS are made in several different models, each intended to accomplish a special purpose. All Everson equipment is designed for the swimming pool—not adapted to it. PANEL MODEL CABIN?

Pool Fittings The adjustable flow inlet, permitting easy balancing of the re-circulating water, and simplifying piping and piping costs, is typi- cal of Everson’s specialization in swimming pool fittings. This adjustable flow inlet can be installed in either old or new pools. Everson Angle Overflow Drains, Trench Grates, Gutter and Floor Drains, Main : Drains and Vacuum Cleaner Connections and fittings are equal in merit in their individual performance. Underwater Lighting Everson Underwater Lights, the result of much engineering research and experimenta- tion, are made in four different styles to meet all pool requirements and are equipped with brass or brass chrome plated frames and special heat-resisting lenses. The enhanced beauty of a pool lighted by Everson and the definite safety factor then obtained, prove that Everson lights are designed specifically for underwater lighting purposes and not merely adapted to pool illumination. Observation Windows A modern requirement for swimming pools where aquatic instruction is a vital part of pool operation. Everson observa- tion windows placed in the pool wall below the water level greatly simplify the problem of instructing swimmers. Pool Cleaning Equipment The standard Everson suction pool cleaner for indoor pools is designed to operate direct from the re-circulating pump. For outdoor pools the Everson portable, self-priming, suction pump becomes an economical and necessary part of the pool cleaning system. These cleaners operate similar to the ordinary domestic vacuum cleaner except instead of air, water is used as suction principle. Pool Accessories The appointments of any pool should be up-to-date, equal to the attendance demands, and have an economical functional utility based on quality products. Everson offers selective equip- ment exactly suited to any pool large or small, indoor or out- door.
