Many different companies throughout a number of industries rely on our static mixers. We know they’re high quality products, but it’s nice to see that in action. Our Case Studies page offers insight into how many of our pieces of equipment are used, but we found this one to be particularly notable.
In the world of power plants, the biggest source of waste water is the water that comes when the ion exchange that is utilized to demineralize the boiler feed water is produced. Before it can be discharged from the plant, though, acid must be injected to help neutralize it, as most regulations have said that it has to have a nearly neutral pH before it can actually be introduced back into the sewer system. It’s this acid injection process that brought us into the picture thanks to the needs of a Utah based energy company.
Before they came to us, they were using a neutralization tank that had a propeller style mixer, then a secondary tank that also included a propeller style mixer. These two tanks were not only space hogs, they covered 400 square feet of plant space, but they were energy hogs as well. They were ocnsuming up to 65,000 kw-hr annually. What’s more, though, is that the pH probe in the tanks was continually fouling up thanks to the acid, and the tanks had to be cleaned every year thanks to a high level of sludge build-up. The cost of the annual maintenance regimen was nearly $25,000.
When they called Komax, we recommended a 3″ Teflon lined static mixer with one of our optional injection ports. We also suggested placing the pH probe downstream of the mixer, which meant immediate feedback to the dosing pumps.
The results were nothing short of stunning. Serious energy costs were recouped and maintenance labor was reduced. They’ve also managed to achieve consistent control over the neutralization process.
