Abstract
the objective of the study is to extend the data given in the report on entrainment to sediments with small particle sizes. The study of entrainment of finer particles is of interest to the operation of settling tanks commonly used to remove solids from water. The turbid water is introduced at one end of the settling tank and allowed to flow slowly through the tank so solid particles can settle to the bottom and be removed. Particles which settle to the bed may also be reentrained by the flow in the tank and be carried away in the effluent, thus reducing the efficiency of the tank.
