Population growth, combined with a lack of land for new clarifiers, is putting a strain on wastewater plant operators in a number of places across the country. Smaller, more efficient clarifiers can provide the solution in a cost-effective manner. The key to their performance is rooted in flow control while optimizing detention times, energy inputs, and the use of coagulants. In this Water Talk interview, Tom Grubb, technical sales manager for...  Continue Reading..

Most groundwater sources are plagued with iron, manganese, and other contaminants that require removal as part of drinking water treatment. However, older techniques for addressing this have proven to be labor-intensive and time-consuming. In this Water Talk interview, Frank Caligiuri, vice president of sales for Hungerford and Terry Inc., discusses the more current and much simpler treatment methods for potable water that have been successful...  Continue Reading..

When it comes to trihalomethanes, the disinfection byproducts also known as THMs, a range of methods are available for their removal from water as well as avoiding their creation altogether. While sophisticated, those solutions offer little or no insight into the process. In this Water Talk interview, Rick Bacon, CEO of Aqua Metrology Systems, and Cliff Tormaschy, CEO of Medora Corp., discuss the use of real-time data to identify THM threats and...  Continue Reading..

Excessive amounts of diverse microorganisms, also known as biofilm, significantly impact water quality and promote corrosion in distribution systems. The fastest way for biofilm to proliferate is through ineffective management. However, taking control isn’t as simple as adding plenty of disinfectant to the water, and traditional testing involves sending samples to a lab and waiting days. In this Water Talk interview, Dave Tracey, director...  Continue Reading..
