The study was undertaken to determine the characteristics of municipal applications in which diatomite filters may be used successfully, to study the effect of various variables on filtration economy and effectiveness, and to outline a procedure for designing a plant to operate with maximum economy. Diatomite filtration equations were developed to predict the head loss-time relationship during a filter run by use of empirical filter cake resistance measurements. An equation was developed to predict filter cake resistance from measureable filtration variables. Empirical constants in the prediction equation were collected in pilot filter runs. A digital computer program was prepared to use the equations and cost information to optimize plant design.
