Now in its third year, WaterVent is expanding its successful event from London, the European hub for venture capitalists, to Philadelphia, a city that is recognized as a hub for innovation in water technology. WaterVent is attended by researchers and decision makers from universities, economic development accelerators, investors, utilities and government entities from the U.S., as well as from Canada and Latin America.

Pasteurization Technology Group (PTG) is the first and only company in the world to combine wastewater disinfection with renewable energy generation. PTG’s patented technology is a highly efficient, cost-effective and sustainable solution that enables the non-chemical disinfection of wastewater while generating renewable energy. The technology is attracting the attention of businesses and municipalities that want to realize substantial energy cost savings and eliminate toxic chemicals through alternatives to traditional UV- and chlorine-based wastewater disinfection systems.

Ventura Water (Ventura, California) recently completed a successful initial evaluation phase of a project to transition its wastewater treatment plant to a safe, non-toxic, sustainable technology to replace the current chlorine-based disinfection process in use at the Ventura Water Reclamation Facility. PTG’s technology has been certified by the state of California for non-potable reuse under the stringent standards of Title 22.

The PTG eco-friendly system for wastewater disinfection and renewable energy

PTG’s patented technology uses either digester gas (often referred to as biogas, a natural by-product of wastewater treatment) or natural gas to fuel a turbine or engine that generates renewable electricity. The hot exhaust air from the turbine or engine—energy that would otherwise be wasted—is then passed through a series of heat exchangers that increase the temperature of the wastewater to a level that disinfects the wastewater stream. PTG’s technology is significantly more cost-effective and more energy-efficient than other methods. And, unlike other wastewater disinfection approaches, PTG’s systems do not require toxic chemicals (such as chlorine) or costly electrical power and expensive UV lamps. PTG is experiencing rapid growth as wastewater treatment plants face the challenge of cost-effectively disinfecting wastewater and trimming operating costs.

About Pasteurization Technology Group California-based Pasteurization Technology Group (PTG) is a venture-capital backed company that is revolutionizing the disinfection of wastewater. PTG’s systems feature its patented “two-for-one” technology that combines eco-friendly wastewater disinfection with the generation of renewable energy. PTG’s process is one of only a handful of technologies to pass the stringent standards of Title 22 in the state of California for the disinfection of water for reuse. By channeling the typically wasted exhaust heat from a turbine or engine to disinfect wastewater, PTG’s process is able to deliver the most energy-efficient and lowest-cost solution on the market. PTG has won numerous awards including the 2012 Artemis Top 50 Water Tech award and the Popular Science 2011 “Best of What’s New” award.
