ABSTRACT:
A cathodic protection system for metal water tanks in which one or more anodes are attached to a buoyant suspension unit. The suspension unit is secured by guys to both the walls and the floor of the tank, thus minimizing ice damage and system incapacity during winter months. The buoyant suspension unit is formed by individual flotation buoys joined in a dual, concentric ring connection pattern, allowing efficient and effective use of wire type anodes. The geometry of the suspension system is designed to keep the anode off the floor and to maintain the anode in the approximate vertical center of the body of water between normal high and low water levels. An ice protecting cap is positioned over the lead inlet. The dual concentric ring provides a more stable system, but also enables the lead connections to extend around the outer ring avoiding both electrical and mechanical interference with the anode wire.
