Peripheral drive clarifiers from Schreiber are designed for applications such as stormwater and primary and secondary clarification. The peripheral drive system uses leverage rather than center-drive torque to rotate the scraper and skimming assembly, resulting in a simplified mechanical system. All the equipment necessary for the continuous removal of floatables and settled solids is suspended from either a rotating bridge or, for smaller units, a lightweight rotating beam arm. The rotating skimming equipment removes floatables regardless of wind direction, and the helical scrapers transport settled solids to the center of the basin in a single revolution. The design allows for the lifting of equipment above the water level for inspection or maintenance without having to dewater the basin. 205/655-7466;
