Title:
OPERATION OF TUBULAR MEMBRANE SEPARATOR
Document Type and Number:
Japanese Patent JPS5454976
Kind Code:
A
Abstract:

PURPOSE: To curtail power and installation costs and enhance washing effect without the use of feed pressure specifically at the time of washing by making washing by passing elastic body only into the partial row of basic group arranged in parallel and afterwards by passing the elastic body even into the other row by turn.

CONSTITUTION: The liquid P is sent through the high pressure pump 1 and the elastic body circulating device 2 into the pipe 8, e.g., by a method in which the valves 3b to 3f are closed, only the valve 3a is opened, and then the liquid P and balls are sent to the pipe 8a. In this case, balls are sent energetically to the module basic group 4a consisting of the module 4a' by means of the liquid P. Then, after the membrane surface is washed by the balls, the liquid and balls are sent to the pipe 9a from the rearest module 4a'. And, the liquid is passed even to the directions of 9b and 9c, but the balls are passed only to the module basic group 5a. Furthermore, the balls are passed to the module basic group 6a, the pipe 11a, and the module basic group 7a, and then partial cocentrated liquid dispersed in the pipes 11b, 11c, etc. are combined at the pipe 12 to return to the circulating device 2 with balls
