APPARATUS FOR BACK WASHING BY VALVE CONTROL OF PUMP ROOM AND OPERATION METHOD OF SAME

摘要

A back-washing system by a valve control of a pump chamber according to an embodiment of the present invention includes a make-up water line, a surface water line, a layer water line, a first back-washing line, a second back-washing line, a make-up water discharge line, and an elevated water tank. In addition to this, the back-washing system includes a make-up water supplying pump, a surface water supplying pump, a deep water supplying pump, a make-up water discharge valve, a first surface water supplying valve, a second surface water supplying valve, a first deep water supplying valve, a second deep water supplying valve, a first back-washing water supplying valve, and a second back-washing water supplying valve. Accordingly, a back-washing system by a valve control of a pump chamber and an operating method thereof according to an embodiment of the present invention provide an excellent washing effect by applying a water pressure due to the surface water supplying pump or the deep water supplying pump simultaneously with a water pressure of the make-up water due to a differential head of the elevated water tank to the deep water line or the surface water line.
