2026 EUCCW

A Novel Oxidizing Biocide for Enhanced Microbial Control in Cooling Systems

January 19, 2026

02:00 PM - 02:30 PM

Instructor: Jo Anna Ordonez, VP, Utility Water Applications, Water Tech, Inc.

Microbial control in cooling water systems remains a persistent challenge for power plants. This session presents a case study on a next-generation oxidizing biocide applied at a Midwest coal-fired power plant. Formed by reacting sodium hypochlorite with a non-toxic mineral catalyst, Oxi-Plus delivers superior microbial control across a wide pH range, without the need for complex on-site generation or supplemental acid addition.

Field testing showed the biocide reduced sodium hypochlorite use by 88%, eliminated sulfuric acid handling, improved condenser vacuum by 1" Hg and cut annual CO₂ emissions by an estimated 1,827 metric tons. With extended stability, benign byproducts, and straightforward monitoring via ORP and chlorine residuals, it demonstrated both operational and environmental advantages.

Attendees will learn how novel oxidizing biocides can transform cooling water programs, offering utilities a safer, more sustainable and effective approach to microbial control.

"This is my first year at POWERGEN and so far I can just say, wow, this event is huge. I never thought I would have access to so many different vendors and so many different experts in the energy industry by coming to an event like this."

"It's my first time at POWERGEN. I'm having a great time walking around and seeing all of the booths in the exhibit hall and everything that everybody's trying to sell me, as well as a lot of very useful technical presentations. My particular favorite has been the carbon capture track, but they've all been good that I've attended so far."

"Hi, I’m Chad Lemoine with Entergy... here as a corrective actions program specialist. It’s my first time at POWERGEN, so it’s been great for networking. I’ve met personnel at our plants I’d only talked to on the phone, so that face-to-face interaction has been really good. I’ve enjoyed meeting new people, learning about what they do, and how it interacts with my work... Overall, it's been a really good time."

"I think my favorite part of the conference has been essentially the Smarter Power Plant Track. There's been a lot of good [takeaways] for us because our plans are quite old, so there's a lot of manual readings and things, but me being the IT generation, I think it could be done better. So having a lot of these [takeaways] from companies who have [accomplished what] we are wanting to do is great. It's been really eye opening networking with all of the exhibitors [as well]. It's my first time here, but I don’t think it's going to be my last."

“Nel’s chosen to sponsor and be part of POWERGEN because it's one of the more important shows in the hydrogen market, also the power generation market in general. Over the years, we've seen a shift in POWERGEN from more traditional power generation to a greater presence with renewables, and now with hydrogen, as an energy source, moving into the future.”

“We're here today at the conference because I believe this is the largest power generation conference there is in the country. One, it's a way to get our name out and that's why we're sponsoring it. But two, it's also a great way to connect with other groups, other organizations and, you know, meet the people who are actually important for our own progression as a company.”

“We come to POWERGEN every year because it's a great show you can make great contacts in the renewable space, great contacts in the data center space, great contacts in the commercial industrial space. So that's why we're here every year. You should be here too.”
