There are many cool aspects of my job, not the least of which is learning — and sometimes even breaking news — about the latest technologies in water and wastewater. When I heard from Mike Dejak, executive VP of Eco-Tec, that the company’s new technology could “revolutionize filtration” for the produced water market, I was anxious to learn more about it. However, I was also duty-bound to you, the reader, to investigate the validity of such claims. The inquiry is the latest entry to our Views From The Top Q&A series.
Oxidizing antimicrobials, such as chlorine, are common disinfectants used to treat water. Test strips, DPD kits, and colorimeters are currently the most popular methods for determining the relative disinfecting power of oxidizing antimicrobial agents in these applications.
Everyone in the water and wastewater industry knows and measures pH. Conductivity is a concept we all readily grasp. Dissolved oxygen and free chlorine are easy to understand since they refer to actual chemicals. But ORP is another matter. If you know that it stands for oxidation reduction potential, you are already in a select minority.
Hydrogen sulfide is probably the most obnoxious and troublesome compound to be dealt with in a potable water supply. If hydrogen sulfide is present in the raw water then it is an almost impossible task to produce a palatable water that is free of taste and odor at all times.
