The spillway has a calculated and uniform overflow of water from the tank and the ability to regulate it. It is no secret that if discharge rates in sedimentation tanks are violated, it is impossible to maintain the required indicator for suspended particles. Also, an adjustable gear spillway makes it possible to work uniformly throughout the sedimentation tanks in all of its areas, thereby reducing the removal of suspended particles.
The use of serrated spill edges improves the efficiency of structures, eliminates possible errors in construction and installation, as well as the destruction of the structure surfaces during operation.
Advantages of using gear drainage made of polypropylene:
- Toothed spillway is less sensitive to wave phenomena and elevation differences compared to even weirs.
- The spillway is made of polypropylene and is not subject to fouling by microflora, chemically resistant.
- Durability and high strength. The durability of the polymer material is 50 years. And if necessary, it's easy to replace several polymer modules that have failed.
- Hygienic licenses, certificates, passports for products are available for the spillway.
- The installation of a gear spillway made of polymer can be done without the full sump emptying and it takes 3 to 4 days.
