ABSTRACT:
In order to clean a screen in a waste water purification plant a surge of a body of water is generated by the agency of a dump flushing apparatus, which surge drops in a free fall towards the screen to be cleaned. This surge of cleaning water is given a dimensional extent which ensures for a substantially simultaneous impinging of the body of water onto the total extent of the screen. A framing which surrounds the screen encompasses this surge of water such as to guide the water and to force the water to flow through the screen. During the cleaning or flushing action the contaminants adhering to the screen, which contaminants are substantially of a thixotropic nature, will be removed from the screen and flushed through a sump towards the water purification section of the water purification plant.
