It’s that time of year again; reviewing contracts and sweating over the fact of having to notify clients about pricing changes. Why do we get so concerned? Other industries have no issues with raising prices — think of the increases we have come to know on a yearly basis including electric, cable, water, and property taxes to name just a few. However, our increases usually come with improvement of our services yet we still worry about customer’s reactions. Luckily, I have some good news: It’s time to stop worrying because there are more benefits than downsides of warning our clients about price increases.

Everyone wants pathogen-free drinking water, and adding chlorine is a great way to get it. Unfortunately, the dirtier a water treatment plant (WTP)’s raw water inflow — in terms of natural organic matter (NOM) or microbial organisms — the more disinfection byproducts (DBPs) the chlorination process will generate in the form of trihalomethanes (THMs) and haloacetic acids (HAAs). Those DBPs increase the risk of non-compliance with the U.S. EPA’s Disinfectants and Disinfection Byproducts Rules. Choosing the right instrumentation to measure NOM through spectral absorption coefficients (SACs) can have a big impact on treatment strategies — in terms of both costs and compliance performance.
As with so many other drinking water treatment processes, corrosion control demands a delicate balance among multiple factors. From the water-purifying chlorine that increases corrosion risk, to alternative strategies that reduce corrosion — using either elevated pH or phosphates — keeping corrosion under control requires sound strategy and reliable execution. Here are several approaches to addressing those conditions, along with options for better, more effective corrosion control.
