Environetics Clearwell BafflesMike Gillespie
Environetics Clearwell Baffles can be installed in Clearwells to upgrade the performance of disinfection systems to meet the Contact Time (CT) requirements contained in the Safe Drinking Water Act (SDWA).
The benefits of Clearwell Baffles are:
- Prevents short-circuiting
- Improves disinfection efficiency
- Provides longer detention time
- Improves mixing
- Eliminates dead zones
Baffles increase the baffling factor (BF) in a Clearwell. For example, a low BF (0.1) indicates poor hydraulics caused by a low length-to-width ratio and high inlet and outlet flow velocities in the tank resulting in short-circuiting. Conversely, a high BF (1.0) shows perfect plug flow through a tank with no dead space, high length-to-width ratios, and no short-circuiting.
Clearwell Baffles increase the detention time in the basin by diverting the flow of water on a longer path. This helps ensure the disinfectant has adequate contact time to kill harmful bacteria or viruses in the water. In addition, this extended detention time helps produce predictable disinfection results to meet the treatment standards set out in the SDWA
Increased Retention Time
The Environetics DIRECTOR™ III Clearwell Baffles are designed to meet SDWA treatment standards cost-effectively.
The flexible panels of reinforced synthetic rubber can be attached directly to new or existing Clearwell walls, floor, roof, and columns, creating a barrier that diverts flow along an extended path. This longer flow path increases detention time in the basin, providing more efficient and predictable disinfection results.
Adding Clearwell Baffles is a cost-effective way to upgrade existing disinfection systems to meet required treatment standards without costly modifications or the construction of new treatment facilities.
NSF Standard 61 Certified Materials
Environetics uses a high-quality potable grade XR®-3PW synthetic geomembrane material. This material is specifically designed to provide long-term system performance and be safe for use in drinking water.
This field-proven membrane material is polyester reinforced, which provides excellent dimensional stability and structural integrity, making it durable and long-lasting. Additionally, this material is certified by NSF International Standard 61 for use in public drinking water supply systems.
NSF Standard 61 certification ensures that the material has been tested and evaluated to meet strict health and safety requirements, including the ability to withstand exposure to chemicals commonly found in a drinking water treatment system. This certification ensures that Clearwell Baffles are safe and suitable for drinking water applications.
The flexible panel design of the DIRECTOR™ III Clearwell Baffle systems is designed to make installation easy, even in new or existing below-grade or above-ground structures. The panels can be rolled or folded, allowing easy transportation through manways or inspection hatches. This feature eliminates costly structural modifications and makes the installation process more efficient and cost-effective.
The ability to transport the panels through manways or inspection hatches is critical when retrofitting existing below-grade structures where access may be limited. Using Clearwell baffles allows the installation to be completed with minimal disruption to the existing network and without significant modifications. Environetics baffles are attached with a stainless steel perimeter anchoring system.
Installation flexibility makes the Environetics Clearwell baffle system an ideal solution for water treatment facilities looking to upgrade their disinfection system and cost-effectively meet SDWA standards while minimizing disruption to their operations.
