Water reuse may be the moment’s most talked about treatment industry topic. It’s no wonder that as drought persists in regions throughout the world without sign of subsiding, questions about how we can make the most of our water are being asked.
You can’t control what you can’t measure. It seems simple enough, but accurate measurement can be one of the more complicated aspects of operating a water, wastewater, or industrial plant. There are unexpected hiccups in the process that can alter recordings, hazardous conditions to contend with, and tons of data to collect and analyze.
Changing environmental conditions and increased regulatory oversight have combined to make discharge one of the most pressing concerns for wastewater treatment plants (WWTPs) today. While many plants have found that they need to step up their treatment game to keep up, it can be a challenge to find improvements that are effective and efficient.
Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the variable frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount Analytical free chlorine and fluoride sensors and analyzers from Emerson Process Management.
When water makes contact with the electrical controls in a wastewater treatment plant the results can be costly, and the response can test a plant’s major service supplier.
This is the first of a three-part series examining wipes in the waste stream. This first installment looks specifically at the growth of disposable wipes usage within the last decade.
Utilities are under constant pressure to reduce costs, meet regulatory requirements, and improve sustainability. Finding the best way to meet these goals is a constant challenge.

The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?

The groundwater that a southern Louisiana water utility supplies to local residents has traditionally carried a high amount of organic material and color. In the past, the organics were oxidized and broken down by chlorination, but this practice had gone out of favor due to production of disinfection by-products (DBPs) such as Trihalomethanes (THMs) and Haloacidic Acids (HAAs).
