Operating Experiences at Philadelphia Suburban Treatment Plants
Philadelphia Suburban Water Company management has a progressive attitude toward new developments in water treatment. The article discusses new practices that were adopted as soon as they were proven, including: the use of activated carbon in the early 1930's shortly after it was first introduced to the water industry; the adoption of chlorine‐ammonia treatment in the early 1930's; the use of free‐residual chlorination in 1941; and, chlorine dioxide in 1945. The membrane filter technique for bacteriologic examination of water was first used about 1950, and the method has since continued to play an important part as a supplement to standard bacteriologic procedures. A separate research department was established in 1958 to improve the existing treatment methods and analysis, and develop new and better methods. A discussion by Reginald B. Adams of the Wilkinsburg‐Penn Joint Water Authority, follows the main body of the article, and suggests that, in addition to the methods discussed for checking the passing of activated carbon through the filters, a simple application of the membrane filter should be included. Manganese colloids and carbon passing through the filters are checked routinely with membrane filters at Wilkinsburg‐Penn Joint Water Authority. Filter runs are regulated on the basis of these tests more often than by loss of head.
