The objective of a conventional treatment plant is to produce floc of such size and density that the major portion will settle out in the allowed settling time, and the amount of remaining turbidity will be removed by the filter. Strength of the floc is one factor that affects the success with which suspended solids are removed from the water in the various unit operations. This paper reviews some of the factors that may affect floc strength, and describes a method for measuring the relative strength of floc formed under various conditions.
