Troughs & Weir Pans

Our Troughs and Weir Pans are designed to meet the demands of circular, square, rectangular, or custom tank applications. These products serve critical functions such as filtering, thickening, clarification, flocculation, scum removal, and backwashing, ensuring optimal water treatment performance. Available in NSF/ANSI 61 certified materials and compliant with AWWA F101 standards, they meet the highest industry requirements for both quality and durability.

Each trough and weir pan is custom molded to precise specifications, offering flexibility in design with options for flat, round, V-shaped, or tube bottoms. Whether you need a solution for a small-scale operation or a large industrial facility, our products are crafted to fit your exact needs, helping to streamline your processes and improve efficiency.

Proudly manufactured in the United States, our troughs and weir pans are produced at ISO 9001-certified facilities, reflecting our commitment to excellence. As Henry Ford once said, “Quality means doing it right when no one is looking.” We take pride in upholding this standard in every product we deliver, ensuring reliability and long-lasting performance.

Weirs & Baffles

Weir plates play a critical role in regulating water flow into launders or troughs. Our weir plates are precision-engineered using match metal die molding and are available with flat, V-notch, or square-notch crests. We offer sizes up to 16 feet in length and 4 feet in height to meet diverse application needs.

Baffle scum plates are positioned in front of the weir plates to prevent floating solids from entering the launder or trough. These plates are also produced through match metal die molding or fabrication. Additionally, our custom-molded baffle supports are available in proprietary gusseted or L-shaped designs, accommodating the use of mechanical cleaning devices. Sizes are available up to 16 feet in length and 4 feet in height.

All plates are manufactured in compliance with AWWA F102 standards, ensuring high-quality materials and performance.

Density Current Baffles

Enhance the performance and efficiency of your clarifiers with our precision-engineered density current baffles. Designed to optimize water flow dynamics, these custom-made baffles effectively direct the flow of water, significantly reducing turbulence and improving overall clarification. By promoting smoother, more controlled water movement, our baffles help increase the settling of solids and maximize the operational efficiency of your clarifiers. Crafted with durability and functionality in mind, our density current baffles are a smart investment for any water treatment system looking to achieve superior clarity and performance.
