The Peripheral Drive Circular Bridge Clarifier is designed to have the bridge move helical scrapers along the floor of the clarifier to remove the settled solids in one rotation. This clarifier is run on a .5 hp motor and is designed to fit clarifier tanks from 20’ to 200’ in diameter. It has a very durable and long-lasting design. The bridge clarifier is designed to access the helical scrapers on a hoist without dewatering the tank.

The Peripheral Drive Circular Beam Clarifier is designed to have a fabricated beam move helical scrapers along the floor of the clarifier to remove the settled solids in one rotation. This beam clarifier is used in two applications, the first being within the GR configuration for the aeration process, where the clarifier is in the center of the aeration basin. The second application is where a fixed bridge is in place. The beam clarifier is typically used on smaller installations from 20’ to 90’ in diameter. The beam clarifier requires a hp peripheral drive motor and smaller wheels than the bridge clarifier.
