ABSTRACT:
The invention is a method for using periphyton to treat flowing water in a waterway. The periphyton reduces the quantity of undesirable chemicals polluting the water. Fish, in turn, control the density of periphyton by grazing on the periphyton and convert the undesirable chemicals associated with the periphyton into removable forms such as fish tissue or fish feces.
