Floc Volume Concentration

Abstract

The objectives of the experiments presented in this article were to find a procedure for measuring floc size and volume concentration during mixing, and to explore through jar tests the rapidity of the reactions in forming the hydrous oxides and the relations, if any, in the rapid initial mix between G, or Gt, and the volume fraction and the size distribution. As the velocity gradients in a stirred jar vary widely from point to point at constant speed, it was necessary to adopt in the experiments the temporal mean velocity gradient for G.
