Promising and Affordable Solution to Sludge Treatment

摘要

The process concepts, facilities, case histories, and advantages of an innovative sludge ozonation and dewatering system (Oxyozosynthesis tm) are introduced. The new system is specifically designed for affordable sludge disinfection, stabilization, thickening and dewatering in industrial urban areas. Major unit operations and processes include: (a) sludge collection, flow equalization and pH adjustment in a wet well; (b) oxygenation and ozonation of sludge in a pressurized vessel; (c) flotation thickening; (d) sludge press dewatering; and (e) resource recovery as fuel, or ultimate disposal by sanitary landfill. Two full-scale oxyozosynthesis systems have been installed at the West New York and Hoboken Sewage Treatment Plants, both in the State of New Jersey, USA. Actual operational data are presented.
