  • Publication number: 20230372842
    Abstract: A launder cover system for reducing or eliminating sunlight exposure so as to prevent algae growth in a tank such as a clarifier tank. The launder cover system generally includes a plurality of support members and a plurality of launder covers which are each independently pivotably connected to a tank wall of a tank, such as by using a mount. The support members are each pivotably connected to the tank wall by a pivot connector and the launder covers are each pivotably connected to the tank wall by a hinge connector. Each support member is positioned between a pair of launder covers, and each launder cover is positioned between a pair of support members. The support members function to support the launder covers in a raised or lowered position. A launder support may be connected to the channel wall to support the launder covers in their lowered positions.
