Use of Molecular Filter Membranes for Water Potability Control

filter techniques for the quantitative estimation of coliform organism density in water supplies and waste water disposal systems have been developed intensively during the past 5 years. The results obtained from a wide variety of natural and treated waters show that membrane filter techniques have several advantages over the standard fermentation tube method. At the same time, certain limitations in the new technique have become evident. The purpose of this discussion is to consider the relative merits and limitations of the new
