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® 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.

    Also available is a complete under-drain system (Bio-Drain) designed for use with plastic biological media.  The underdrain system consists of modular structural components that are as easy to install and use as the random dumped media.

    Additional details on these products can be found on Product Bulletin #850 for Bio-Rings® and on the cut sheet for Plastic Jaeger Cascade Bio-Rings® and Bio-Rings®.  Other biotechnology products can be found in Product Bulletin #100 or contact Jaeger for the latest information.
