The northern California town of Graton has signed a contract with Pasteurization Technology Group (PTG) for the purchase and installation of PTG’s chemical-free wastewater disinfection system to handle all the city’s sewage treatment needs. By switching from a chlorine-based wastewater disinfection system to PTG’s safe, sustainable wastewater disinfection technology, Graton will realize significant operational savings and meet or exceed state water quality standards.
The innovative disinfection and cogeneration system is the linchpin of an $8.5 million project to update and upgrade the 36-year-old wastewater treatment plant, which serves the 1,700 residents of Graton. The new PTG X-500 wastewater disinfection system, which represents less than one tenth of the total project cost, can process up to 576,000 gallons per day—easily sufficient for Graton’s 1,700 residents. The system is planned for delivery in the spring of 2013, with project completion expected by January 2014.

Graton, California Selects Pasteurization Technology Group’s Chemical-Free Wastewater Disinfection System
This is a pretty novel idea. Reading the article through, it seems to be a good use of energy. Up front costs might be higher, but operating costs look to be lower. Pasteurizing is the same process they use to kill bacteria in milk.
