AIR CONTROL ACTUATOR AND SUBMERGED MEMBRANE MODULE AERATION SYSTEM USING THE SAME

摘要

PURPOSE: An air controlling actuator and a circulating aeration system for a submerged membrane module using the same are provided to increase the washing effect of the submerged membrane module and to save power consumption. CONSTITUTION: An air controlling actuator includes a tubular introducing pipe, a small sized motor cylinder, a branched pipe, and a discharging pipe. Air is introduced from a blower(210) to the tubular introducing pipe. The tubular introducing pipe includes three distributing holes. The cylinder is contracted in the introducing pipe. According to the contraction of the cylinder, the cylinder adjusts the opening state of the distributing holes. One side of the branched pipe is in connection with the distributing holes, and another side of the branched pipe is formed into one pipe. The discharging pipe is in connection with another side of the branched pipe and discharges air form the branched pipe.
