Like the little engine that could, the University of Nevada, Reno experiment to transform wastewater sludge(烂泥,泥泞) to electrical power is chugging along, dwarfed1 by the million-gallon tanks, pipes and pumps at the Truckee Meadows Water Reclamation2 Facility where, ultimately, the plant's electrical power could be supplied on-site by the process University researchers are developing. "We are very pleased with the results of the demonstration3 testing of our research," Chuck Coronella, principle investigator4 for the research project and an associate professor of chemical engineering, said. "The process to dry the sludge to make it burnable(易燃的) for a gasification(气化) process, which could then be transformed into electricity, is working very well. This is an important step for our renewable energy research, processing about 20 pounds an hour of sludge in a continuous-feed system to produce about 3 pounds an hour of dried powder."

The team of researchers custom built the processing machine in a lab at the University and brought it to the plant for testing. It uses an innovative5 process with relatively6 low temperatures in a fluidized bed of sand and salts to economically produce the biomass fuel from the gooey(胶粘的) sludge.

The new patent-pending, low-cost, energy-efficient technology is an experimental carbon-neutral system. The solid fuel it produces will be analyzed7 for its suitability to be used for fuel through gasification, and the refrigerator-size demonstration unit will help researchers determine the optimum(最适宜的) conditions for a commercial-sized operation.

"The beauty of this process is that it's designed to be all on-site, saving trucking costs and disposal fees for the sludge," Victor Vasquez, a University faculty8 member in chemical engineering and collaborator9, said. "It uses waste heat from the process to drive the electrical generation. It also keeps the sludge out of the landfill."

Estimates, which will be further refined through the research, show that a full-scale system could potentially generate 25,000 kilowatt-hours per day to help power the local reclamation(开垦,收回) facility.

The demonstration-scale project is a collaboration10 with the cities of Reno and Sparks, operators of the wastewater plant. The city councils signed an interlocal(地区间的) agreement recently to allow the research to integrate into their operation, providing space for the experiments, the dewatered sludge(干污泥,脱水污泥) and other resources to help make the project a success.

"Economically, this makes sense," Coronella said. "Treatment plants have to get rid of the sludge, and what better way than to process it on-site and use the renewable energy to lower operating costs. This demonstration gives the University an opportunity to involve students in development of waste-to-energy technology, which ultimately will benefit the community. It's a win-win for everyone involved."

"Our next step is to do exactly what this dryer11 is doing on a much larger scale," he added. "We plan to demonstrate the technology at a scale 100 times larger, to convince investors12 and plant operators of the technology's viability13."

The University's Technology Transfer Office, with assistance from the College of Business, is supporting the project with plans to make the system available to hundreds of communities around the country that operate water-treatment plants.

For example, there are approximately 700,000 metric tons of dried sludge produced annually14 in California municipalities, which would sustainably generate as much as 10 million kilowatt-hours per day.

The project is funded through the Energy Innovations Small Grant Program, the California Energy Commission and the Department of Energy. This phase of the project was selected for funding by the University's Tech Transfer Office under a DOE grant to support transferring technologies from the lab to practical application.

The project is one of many of the University's renewable energy research areas that have commercial potential to help Nevada's economy grow.
