Abstract

This process involves the flowing of wastewater across a mass of zebra mussels that are attached to a fixed media such as a steel plate. The filtering action of the zebra mussels will remove contaminants. These contaminants will be used as food and incorporated into the mussels body tissue or excreted as feces. Filtered material that is not used as food is encapsulated and excreted as psuedofeces. Periodically the accumulated feces and psuedofeces, along with dead mussels, will have to be removed from the system.
