Abstract: The solids flux theory has traditionally been used for clarifier design. However, it's use for analysis of clarifier behavior in operating plants has been largely overlooked due to the intensive data requirements and complex ...

Abstract: A model for predicting the rate of rise or fall of a sludge blanket in an overloaded or underloaded condition is developed from the steady state solids flux theory of clarification. The model was verified with results from ...

Abstract: The series‐event kinetic model is applied for the analysis of chemical disinfection data sets exhibiting initial resistance characteristics. Use of the mathematical model permits a generalized approach for data reduction ...

Abstract: A gravity drainage model was developed that included terms for cake resistance, filter resistance, and initial ponding. Laboratory scale batch drainage tests were performed at sludge volume loadings between 0.013 and 0.006 m
