Cannibal® Solids Reduction System

The Cannibal® Solids Reduction System reduces the biological solids produced by activated sludge wastewater treatment systems, as well as the costs associated with sludge wasting and removal.

Cannibal Solids Reduction Process
Cannibal® Solids Reduction System
With the Cannibal® solids reduction system, the destruction of biological solids is accomplished through an interchange recycle flow between the aerobic activated sludge process and a specially controlled sidestream bioreactor. This patented technology, which has been proven in many facilities of various sizes and applications, can be used for new plant designs or retrofitted into existing sites.
