Document Description
The proposed project will research the use of nanoscale materials to improve dewatering processes for sewage sludge. The research will take the results of bench scale work that showed nanoscale materials enhanced the performance of polymer additives currently used in the dewatering process. The goal will be to increase the volume of water removed. Currently, dewatering processes increase the percent of solids in sludge from 3 to 4% to approximately 25%. The proposed project will increase the percent of solids in dewatered sludge to approximately 30%. This increase in water removal would save approximately 30% of the energy used in the dewatering process (approximately 240 million kWhr).
