The Application of Filtration Theory to Pilot‐Plant Design

scientific solutions to deep-bed filtration problems. There is a growing use of pilot plants to guide the practical design of filters and for plant operation control not only by universities, research institutes, and large companies, but also by cities and consulting firms.3 However, the wide gap between filtration theory and practice that led Mintz and Camp to the above conclusion still exists. The pilot plant has had to be the missing link between the two. The design and use of a pilot plant without a sound theoretical basis for design of the experiments to be conducted may bring about misleading conclusions, a result not much better than would be achieved by not using a pilot plant at all. The objective of this paper is to suggest a way to apply current filtration theory to the design and use of pilot plants. Following classification of the different physical and chemical mechanisms and parameters involved, the work focuses on those variables that can be
