340 Pinks and Blues: Alkalinity, Part 2

Welcome to another insightful episode of Scaling UP! H2O, the podcast created exclusively for industrial water treaters. In this episode, our knowledgeable host, Trace Blackmore, answers listener-submitted questions and takes a comprehensive analysis of the familiar and critical topic of alkalinity in water treatment.

For our dedicated audience of industrial water treaters, this episode offers invaluable insights into:

Crucial Role of Alkalinity: Understand the pivotal role alkalinity plays in water chemistry and its significance in neutralizing acids, ensuring your systems are resilient against pH fluctuations.

Ion Composition Deconstructed: Gain clarity on the composition and behavior of alkaline ions, including carbonate, bicarbonate, and hydroxyl ions, providing a solid foundation in water chemistry.

pH-Alkalinity Dynamics: Explore the intricate relationship between pH and alkalinity, enabling you to predict and manage water conditions more effectively in your industrial processes.

Tailored Monitoring Approaches: Learn how to tailor your monitoring approach based on the specific needs of your systems, whether it’s focusing on carbonate and bicarbonate in cooling systems or hydroxyl in boiler systems.

Addressing System-specific Concerns: Delve into practical insights on addressing alkalinity concerns at different pH levels, such as avoiding condensate grooving in boiler condensate lines below pH 4.3.

Efficient Testing Methods: Optimize your testing methods by embracing the titration method, and discover the importance of regular cleaning and calibration for accurate and reliable results.

Proven Field Tips: Benefit from field-tested tips, including using phenol failing to verify system flushing and ensuring the proper care and calibration of pH meters, saving you time and resources in real-world scenarios.

This episode is a reservoir of valuable insights that empowers industrial water treaters with the information they need to enhance their understanding of alkalinity, streamline their testing processes, and proactively address challenges in their systems. Tune in to elevate your expertise and make informed decisions in the dynamic world of industrial water treatment.

Alkalinity is a measure of the ability of a solution to neutralize acids. It’s a property of water and other substances, and it’s usually expressed in terms of equivalent concentration of calcium carbonate, in milligrams per liter, or parts per million. alkalinity is a crucial parameter in water chemistry and is often associated with the presence of carbonate, bicarbonate and hydroxyl ions.  In simpler terms, Alkalinity reflects the water’s capacity to resist changes in pH when an acid is added.” – Trace Blackmore


Periodic Water Table With James McDonald

Isothiazoline or isothiazolone. Is there a single molecular formula or is there a family of chemistries available? What is isothiazoline used for? Can you test for it? Does pH have an impact? What dosages are recommended? What microorganisms is it effective against? How much contact time is required for isothiazoline to be effective? What is the mode of action for isothiazoline? What systems is it used in? Is isothiazoline ever blended with anything else?
