Fiberglass (FRP) Clarifier Launder Covers
Controlling growth of algae formed in the clarifier effluent stream is a challenge for today’s modern water and wastewater treatment plants. Left unchecked, algae can change hydraulic dynamics of clarifiers by obstructing weir design features typically found in v-notched weir configurations.
Furthermore, at plants utilizing newer ultraviolet disinfection technology, larger algae strands tend to dislodge and move downstream through the plant to substantially cover UV bulbs making them ineffective and eventually may cause the expensive bulbs to fail all together.
Improving operations, Enduro Launder Covers prevent algae growth plus act as a weather and debris barrier for the launder. In addition, the covers contain odor and gas emissions associated with water and wastewater treatment operations.
Enduro Launder Covers consist of multiple, high strength sections fabricated to the contour of the clarifier or tank. Each section extends from the tank wall inward over the launder and weir to the scum baffle. With superior corrosion resistance and strength, use of FRP components ensures long, maintenance-free service life.
Fiberglass launder covers from Enduro Composites are custom designed for both round and rectangular tanks and provide important value for water and wastewater operations:
- Continuously inhibit algae growth
- Light weight cost effective solution
- Safe, reliable and efficient
- Operable access for inspections and maintenance
- Odor and vapor containment
- Long, reliable service
The FRP launder cover system inhibits (direct) sunlight from reaching the elevated growth areas at the clarifier launder and weir by forming a continuous protective environment above the effluent stream. Once installed, the system provides an attractive yet extremely low maintenance, passive structure designed to eliminate algae growth issues.
Additional benefits of the system help to prevent windblown debris like leaves, plastic bags, etc. from entering the stream and may also help to contain localized odors if present in the effluent trough – weir area.
