Breakpoint chlorination is a key concept in pool chemistry. In May 2017, we published a two-part article about pool sanitizers. In part one we compared different chlorine types, and their pros and cons. This article dives deeper into the science of chlorination. We explore the difference between breakpoint chlorination and hyperchlorination (shocking).
Keith Coursin clears the air: Pool indoor air quality was a big deal before it became a big deal.
As a follow up to part 1 and part 2 of the history of pool indoor air quality (IAQ), I reached out to Keith Coursin, the President of Desert Aire Corp, a prominent pool dehumidifier manufacturer. Coursin has been in the field of HVAC technology since his 20's; in my personal opinion he's one of leading experts on pool dehumidification in the world. This is my interview with Keith Coursin.

Indoor air quality problems are usually equated to chloramine issues. Airborne chloramines are an inevitability with swimming pools, and pool operators alone cannot prevent them entirely. It takes a coordinated effort on both the water side and the air side for healthy indoor air quality to occur. This article is part 1 of explaining the issue.
Chloramines are chemical byproducts of chlorine oxidizing nitrogen-based compounds in water. They are referred to as disinfectant byproducts (DBPs). Normally, it is the incomplete oxidation of carbon, ammonia and nitrogen-based organic waste that creates the long list of DBPs, whereas chloramines themselves follow a specific pattern.
