Baffle Wall Systems from NEFCO are lightweight, high-strength engineered fiberglass panels used in many systems, including activated sludge clarifiers, aeration basins, oxidation ditches and contact chambers. They are available in multiple configurations that can be used to divert flow in a large tank, enclose equipment, or modified to be used as a cover panel to protect framing guides for slide gates or preventing airborne debris from entering the effluent of a clarifier. They are custom engineered to meet design parameters as specified while aiming for optimum performance and ease of installation. Panels require virtually no maintenance and have no parts to wear or replace. 561/775-9303; www.nefco.us.
