Wastewater Disinfection Pioneer, Pasteurization Technology Group, Announces Hiring of Experienced Project Engineer and Opening of a Second Location in Southern California

In Press Releases on

Graham McCarthy brings deep water, wastewater and power expertise, along with proven ability to design water and energy projects, ensuring smooth customer installation processes.

Pasteurization Technology Group (PTG), innovator of the only wastewater disinfection process that creates renewable energy, announces the hiring of Graham McCarthy as Project Engineer. With 15 years hands on experience designing, managing and completing industrial and municipal projects throughout California, Graham brings a deep base of skills and experience to PTG and its customers. His experience includes Combined Heat and Power (CHP) projects, potable water and recycled water systems, along with sewage facilities for both distribution and collection systems. Graham was a team member on the Lake Mission Viejo Advanced Purification Water Treatment Facility Project, which was the first recreational lake in California supplied by reclaimed water. He was also responsible for advancing the design and operation of two prototype technologies: Renewable Energy Desalination; and Zero Liquid Discharge Brine Treatment. Mr. Graham previously worked as a research engineer on the Salton Sea Initiative at the University of California, Irvine connecting professionals and communities concerned with the sustainability challenges of the Salton Sea region.

Graham has co-authored five technical research publications for the Water Environment Research Foundation and the Water Environment Federation in several areas of study including: frameworks for energy neutral wastewater treatment systems; zero liquid wastewater discharge systems; and studies of treatment system efficiency and energy usage.

Graham joins PTG as customer demand is increasing. PTG’s systems provide the highest efficacy in wastewater disinfection, so they are perfectly suited to applications in the agriculture, food, and beverage industries as well as for municipal wastewater treatment facilities.  In all instances, the need for the generation of renewable energy is of particular interest as businesses seek to mitigate the effect of escalating grid power costs.

“Graham is a great addition to our team because he can provide valuable hands-on experience for our customers and for PTG meeting several project requirements, including power generation, wastewater disinfection and water reuse, which represent our unique value propositions,” said Greg Ryan, co-founder and CEO of Pasteurization Technology Group. “With sustainable water and renewable energy growing in focus, our technology is in high demand from customers who want to significantly reduce operating costs, to increase system efficacy, and to achieve sustainability goals.”

PTG is also pleased to announce the opening of its second location in Orange County, California which will provide customers in Southern California additional support and resources.

“I am excited to provide value and additional expertise to PTG, which is growing fast. Having previously worked on successful water and energy projects, I view PTG’s technology as the next logical link in the chain, and I am thrilled to be working here,” said Graham McCarthy, Project Engineer at PTG. “PTG has a great team and awesome technologies, and I am looking forward to helping execute projects successfully for our customers.”

About PTG’s eco-friendly system for wastewater disinfection and renewable energy

PTG’s patented technology is the first and only technology to combine wastewater disinfection with the generation of renewable energy. PTG’s integrated systems can use available waste by-products (such as biogas or biomass), or natural gas, to power a turbine or engine that generates electricity. The turbine’s hot exhaust air (which is typically wasted) is passed through a waste-heat recovery unit that increases the temperature to disinfect the wastewater. PTG’s intelligent software efficiently optimizes energy and water flow throughout the integrated system. PTG’s systems are significantly more cost-effective and energy-efficient than other disinfection methods. And, unlike other wastewater disinfection approaches, PTG’s technology is sustainable since it does not require toxic chemicals such as chlorine, or costly electrical power and expensive UV lamps. As a result, PTG’s systems fit a broad range of applications in both the municipal and industrial market sectors such as agriculture, food, and beverage processing.

About Pasteurization Technology Group

California-based Pasteurization Technology Group (PTG) is a rapidly growing, 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. PTG’s technology has also been officially recognized in the EPA’s influential Guidelines for Water 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’s technology enables tremendous cost savings in water- and energy-intensive sectors such as the agriculture, food, and beverage industries. PTG has won numerous awards including the Katerva Award, the Artemis Top 50 Water Tech award, and the Popular Science “Best of What’s New” award.
