Launder Covers


Algae growth in the launder trough and on weir surfaces is unsightly and will eventually impede weir flow. In some plants, algae in the effluent can significantly reduce the system’s overall efficiency. Algae removal and cleaning is a time consuming and costly issue for maintenance personnel.

Protectolite™ Composites FRP Launder Covers have been designed to inhibit algae growth in the launder trough and on weir surfaces by blocking sunlight. Without needed sunlight, algae growth is generally reduced to a light film that can be washed away with a hose. Constant cleaning by maintenance personnel is no longer necessary. As well as improving the overall appearance and operation of the facility, Protectolite™ Composites FRP Launder Covers help protect launder troughs from ice, snow and debris accumulation.
