ABSTRACT:
A cover apparatus for inhibiting the growth of algae on the fluid-contacting surfaces of a water treatment tank including a central influent, at least one substantially vertical peripheral wall having an upper and interior surface, a peripheral baffle having inside and outside surfaces, a substantially vertical weir, a spillway, and a launder channel having a width. The cover apparatus includes at least one panel member positionable over at least a portion of the launder channel to prevent light from reaching interior surfaces thereof. In a preferred embodiment of the present invention, a plurality of modular panel members are employed to cover substantially the entire launder channel, with each individual panel member being dimensioned to span at least the width of the launder channel and comprising a substantially opaque material.
