How the Self-Cleaning Cylinder Screens & Retrieval Systems Work

The intake / fish screen unit is made up of a rolling center manifold constructed of stainless steel with two stainless steel wedgewire cylinders on either end. This screen unit is easily raised and lowered on tracks with a winch.

When the screen is in place for pumping, the manifold seals against the docking inlet and all incoming water passes through the screen. The screen will periodically run through a cleaning cycle.

A programmable computer controller runs the cleaning cycle and checks the system operation. The screen cylinders are mechanically cleaned by rotating them using a high torque, low speed, marine duty oil hydraulic motor.

The cylinders typically rotate at 4 RPM for one minute in each direction. The exterior of screen cylinder is cleaned by rotating its surface against a stationary brush bar. The interior of the cylinder is also brush cleaned. The internal manifold distributes and promotes even flows along the surface of the screen cylinders.
