TL;DR: In this paper, a simple physical model consisting of a flat surface covered with biologically active slime is used to simulate trickling filter operations, and process variable studies were conducted using glucose as the sole source of carbon in a mixed salt solution.

TL;DR: In this article, the use of rotational and capillary viscometer for experimental determination of non-Newtonian flow parameters of sewage sludges is considered; description of equipment and calibrating procedures are given together with certain experimental results; particular attention is drawn to influence of solids concentration and temperature on sludge-flow parameters.

TL;DR: In this paper, an equation was obtained that established the growth kinetics under batch conditions in an aerobic system of organic wastes, which was then combined with a linear relationship between sludge growth and BOD removal.

TL;DR: In this article, the authors formulated a set of partial differential equations, describing transient operation of trickling filter, and solved the problem by forming material balance, and formulated the set of equations to describe transient operation.

TL;DR: A rational theory of thickener operation, based on the Kynch analysis of sedimentation, is used to develop a design method for thickeners using gravity settling of suspensions as mentioned in this paper.
