While many of the plastic packing offered by Raschig Jaeger can be utilized as biological media in trickling filters, Raschig Jaeger Bio-Ring® and Cascade Bio-Ring® offer specific design features for use in fixed film biological filters. These UV-stabilized products offer increased capacity and efficiency to aerobic treatment of wastewater in new installation or as replacement for rock in existing filters.
 

Raschig Jaeger Bio-Ring®
Raschig Jaeger Bio-Ring ® is a cylindrical element with large, hexagonal windows allowing passage of solids and unique external ribs to provide surface area and strength. Their 3½-inch size makes them ideal for small to mid-size filter applications.
 
 
 
 
 
 
 

 
Cascade Bio- Ring®

Cascade Bio-Ring® is designed for use in larger towers. Its 7¼-inch diameter and 2-inch height is composed of cylindrical, concentric circular sections, internal ribs, and an outer wall design to prevent occlusion of the elements. This design, based on the original Cascade Mini-Ring is the standard for random packing used in trickling filters.
