The goal of this project is to integrate solar, biological, and nano technologies into wastewater treatment concept to create a self-sustaining wastewater treatment system that can significantly reduce mass of the wastewater, and simultaneously generate potable water/renewable energy/fertilizer. The proposed system includes five subunits of solar energy collection, novel anaerobic digestion, combined heat and power unit, electrocoagulation pretreatment, and nano-filtration. The integrated concept has a great potential to be applied by a wide range of waste treatment systems from agricultural wastewater to municipal wastewater treatment. The use of such novel technology would dramatically change the status of wastewater treatment. It will eventually turn the wastewater from an environmental liability into a public and private asset.
