Tests were begun in 1964 to evaluate the efficiency of tube configurations as sedimentation devices and to evaluate means of sludge removal. Preliminary tests with single tubes of various sizes quickly demonstrated that they were efficient sedimentation devices. During these preliminary tests, it was found that the accumulated sludge could be readily removed by periodically draining the tubes, if they were inclined slightly in the direction of flow. An angle of inclination of 5 degrees was found to be adequate for sludge removal by gravity. The potential merits demonstrated in the preliminary tests resulted in the detailed studies that are described in this paper.
