Clarifiers are structures commonly used in wastewater treatment plants or other industrial applications to separate solids from liquid wastewater. They are essentially large tanks or basins designed to allow solids to settle at the bottom while clarified water is skimmed off the top. These clarifiers are often elevated for several reasons, including maximizing space efficiency, facilitating gravity flow and allowing for easier maintenance access.

​

1. Bolted Construction: Unlike traditional welded clarifiers, bolted elevated clarifiers (BEC) are constructed using prefabricated bolted steel panels. These panels are typically made of corrosion-resistant materials such as stainless steel or coated carbon steel. The bolted construction process allows for easier assembly and disassembly, as well as potential future modifications or expansions.

​

2. Elevated Design: Bolted elevated clarifiers (BEC) are often raised above ground level on supporting structures such as structural steel or concrete columns. Elevating the clarifiers provides several benefits, including optimizing land use, subverting high water table issues, facilitating gravity flow of wastewater through the clarifier, and enabling easier access for maintenance and inspection activities underneath the tank.

​

3. Internal Mechanisms: Bolted elevated clarifiers (BEC) may incorporate internal mechanisms to enhance the clarification process. These mechanisms can include sludge rakes or scrapers to facilitate the removal of settled solids, as well as mechanisms to control the flow of influent and effluent within the clarifier.

​

4. Access and Maintenance: Elevating the clarifiers makes maintenance tasks such as cleaning, inspection and repairs more accessible. Maintenance personnel can easily access the underside of the clarifier for inspection and servicing of internal components. If the clarifier is “skirted” to grade with bolted panels, the space below the sloped floor allows for storage of equipment and shields your operation from inclement weather. Additionally,the bolted construction allows for individual panels to be removed or replaced as needed without requiring welding or cutting.

​

5. Customization and Scalability: Bolted elevated clarifiers (BEC) can be customized to meet specific project requirements and can be designed to accommodate varying flow rates and treatment needs. They are also scalable, allowing for easy expansion or modification of existing clarifier systems as wastewater treatment demands change over time.
