The operation of many waste water treatment plants involves the pumping of sludge cake using positive-displacement pumps. This paper discusses the development of a computational model, based on first principles, for simulating the pumping of sludge cake with a relatively low moisture content. It provides a design method that is developed from analysis. The partial differential equations in the model are solved by the method of characteristics. The method of analysis is applied to several sludge-pumping conditions. The model results are compared to the field data. The comparison shows that the model is capable of predicting the transient pressures with in the pipeline.
