Scaling UP! H2O

310 Truths and Misconceptions About Carryover

Louis Godbout of TGWTWelcome to the Scaling UP! H2O Podcast, where we dive deep into the world of industrial water treatment. In this episode, we’re debunking the misconceptions around carryover and exploring the scientific truth behind it. We’ve invited Louis Godbout and Simina Alungulesa from TGWT to share their latest research and insights on the subject. Have you ever wondered what tannins are and what they do? Or what the reason for carryover is? How about the impact of bubble size and defoamers? And what does salt have to do with it all? Don’t miss this episode, where we uncover the answers to these questions and more. So join us and discover how the right chemistry can make cycling-up possible.

Bottom line: Cycling-up is possible for those who dare to use the right chemistry.

“Your cycling up, your savings go down as the cycles go up. If you go from 10 to 20, that’s a big game changer, but from 20 to 40, it’s a diminishing return.” – Louis Godbout

“Most of the time, we find carryover is due to mechanical issues, but if it is combined with high TDS, the problem is really worse, it worsens everything and it makes a boiler more sensitive to any variation in pressure” – Louis Godbout

“How far can we go? How far can we go with this treatment or that treatment?

People overuse antifoams.” – Louis Godbout

“You cannot use conventional antifoams to cycle-up.” – Louis Godbout

“There were many mysteries about tannins, and because the chemistry is complicated, it is extremely complex.” – Louis Godbout

“Tannins react readily with oxygen; they are oxygen scavengers. – Louis Godbout

“We realized that: YES indeed, a lot of the antiforms that are presently used in the industry do have a positive effect on bubble coalescence.” – Simina Alungulesa

“If you look at typical antifoams based on polyglycols, if you put them in boiler conditions, what actually happens is that they degrade into surface-active substances, which means they actually create even MORE foam.”  – Simina Alungulesa

Periodic Water Table With James McDonald

Hydrogen Peroxide or H2O2: While we may find it in our medicine cabinets, it has uses in industrial water treatment, too.  First, what are these uses? How is hydrogen peroxide introduced into a system? Do you purchase pure hydrogen peroxide or is it generated in-situ? If in-situ, what other chemicals are involved? Is hydrogen peroxide fast or slow acting? What can cause a hydrogen peroxide solution to decompose? Is this decomposition reaction exothermic or endothermic? What are the reaction byproducts of decomposed hydrogen peroxide? Can decomposition cause a dangerous situation? How do you test for hydrogen peroxide?
