ABSTRACT
Debris, trash, and other waterborne solids are captured by the bar racks at cooling-water intakes. The volume of solids corresponds to the volume of water that is passed through the intake structure. Therefore, once-through systems are likely to generate a larger volume of solid waste than closed-cycle systems. Wet towers accumulate sludge in the bottom of the towers that must be removed periodically. Dry towers collect some amount of airborne debris, including leaves and paper, on their intake screens. The relatively small solid-waste volumes attributable to all three types of systems are unlikely to cause AEIs.
