NSF - Model 61 - Launder Covers
Our NSF 61 Launder Covers are used in water and wastewater treatment projects as odor control hoods that entrap noxious gases generated in the wastewater treatment process. Launder Covers also prevent the growth of algae which can disturb weir flow by elimination of sunlight; this reduces weir maintenance and enhances flow consistency for optimum efficiency of the system.
Choosing to utilize launder covers versus the brush system means:
- Launder covers never stop working in cold weather
- Algae growth is eliminated
- Overall maintenance costs will be reduced
- Longer product service life
Launder covers are also used to cover other openings where access is needed but for safety and other reasons the opening needs to be covered when not being utilized.
Covers are custom designed and can be used in both round and rectangular clarifiers, sludge thickeners, channels and other openings.
