Abstract
PURPOSE: In a gravity type upper countercurrent two-stage active carbon desorption tower for a medium or large sized plant for use in high order treatment of sewage, it is intended to improve the efficiency of utilization of active carbon by disposing a strainer type collector at an appropriate interval from the surface of an active carbon-packed layer, which is used as a collector for the process water from a second tank.
