Abstract: A method and apparatus for agitating and scrubbing a filter bed in which a tubular arm is disposed in the bed near the top thereof and is adapted for rotation on a vertical central axis. The arm has nozzles extending from opposite sides thereon on respective sides of the center and is caused to rotate in the filter bed by the supply of air under pressure through the arm to the nozzles. Other nozzles can be mounted on the ends of the arm to treat the filter bed outwardly from the ends of the arm. The air supplied to the nozzles may be enriched with oxygen. The filter bed is preferably backwashed by upward flow of water therethrough simultaneously with the agitation and scrubbing of the upper portion thereof with the air jets.

Abstract translation: 一种用于搅拌和洗涤过滤床的方法和装置，其中管状臂设置在靠近其顶部的床中并且适于在垂直中心轴线上旋转。 臂具有从中心的相应侧上的相对侧延伸的喷嘴，并且通过在压力下通过臂向喷嘴供应空气而在过滤床中旋转。 其他喷嘴可以安装在臂的端部上，以从臂的端部向外处理过滤床。 供给到喷嘴的空气可以富含氧气。 过滤床优选通过向上的水流反流洗涤，同时用空气喷嘴搅拌和擦洗其上部。
