A look into pH and Alkalinity
Magnesium Hydroxide Feed Reliability- How Low Can You Go?
Introducing Theresa Kelley, Bookkeeper
As pH and Alkalinity are two parameters that are commonly monitored and controlled in wastewater treatment, it never hurts to take a moment to be reminded of what they are and why we need to control them.
Anyone who has ever worked with a thick, slurry product like magnesium hydroxide knows that the biggest challenge is to figure out a way to achieve reliable feed. Magnesium hydroxide has some fantastic benefits, such as operator safety, improved microorganism activity, improved solids dewatering, and cost savings as compared to caustic soda and lime . . . but you can’t take advantage of these benefits if you can’t figure out how to reliably feed the product!
Theresa began work at IER in January 2016 as a part-time administrative assistant. When IER’s previous bookkeeper retired in early 2020, she accepted the challenge to become IER’s Full Charge Bookkeeper, providing invaluable support and guidance through the sale to Calix and the expansion that IER is currently undergoing. Theresa is now in the process of transitioning back to a part-time role while maintaining a focus on HR and accounting responsibilities.
