Abstract: A system for removing dissolved contaminants, particulate contaminants, and oil contaminants from industrial waste water, the system including a gas floatation and primary oil contaminant removal subsystem including a tank for receiving a flow of the industrial waste water and a flow of gaseous microspheres, wherein the gaseous microspheres combine with oil droplets in the waste water to form flocs which float to the surface and are removed to provide processed waste water with the majority of the oil contaminants removed, and a contaminant removal subsystem for removing dissolved contaminants, particulate contaminants, and any remaining oil contaminants from the processed waste water.

Abstract: Methods for enhancing an activated sludge process including at least one biological reactor. A weighting agent impregnation subsystem is coupled to the biological reactor for mixing biological flocs and weighting agent to impregnate the weighting agent into the biological flocs to form weighted biological flocs. A weighting agent recovery subsystem is configured to recover the weighting agent from the weighted biological flocs and reintroducing the recovered weighting agent to the weighting agent impregnation subsystem.
