Kansas Wastewater Treatment Plant Makes A Long-Overdue UV System Upgrade (Case Study)
Kansas Wastewater Treatment Plant Makes A Long-Overdue UV System Upgrade (Case Study)

The UV disinfection system at the Plant 20 Wastewater Treatment Plant was installed in 2002, but over the years staff continued to struggle with PLC and controls-related issues, ballast failures, and water level management. An overhead crane was needed to operate the water level management device, and water level fluctuations of 12” were common, which contributed to an increase in fouling on the quartz sleeves.

A Holistic Approach To Water Treatment A Holistic Approach To Water Treatment

Not all water is the same, so don't be sold on a "one-size-fits-all" solution. Many treatment providers will attempt to fit a square peg in a round hole, while others — a select few, in fact — can provide a fit-for-purpose solution based on broad, customized capabilities. That's the pitch from U.S. Water Services, which recently became part of Japan-based Kurita Water Industries, a resource- and technology-rich company with global reach.

Forward-Looking Technology Anticipates Compliance Needs Forward-Looking Technology Anticipates Compliance Needs

When a company stakes its reputation on delivering innovative technologies, products, and services, the specter of a changing regulatory landscape is considered more an opportunity than an obstacle. In this Water Talk interview, Mirka Wilderer, CEO of De Nora Water Technologies, discusses varying topics such as pharmaceuticals and nutrients in wastewater, the synergy of the company’s new MIOX and Neptune acquisitions, and how to address the growing concern over chlorate disinfection byproducts (DBPs) in drinking water. For example, De Nora’s new ClorTec Gen III onsite hypochlorite generators generate up to 3,000 lbs./day of chlorine-based disinfectants while reducing chlorate formation and cutting operating costs by 15 percent as compared to previously available models.

An Improved Approach To Turnkey Disinfection Solutions An Improved Approach To Turnkey Disinfection Solutions

Engineered skid systems provide a compact configuration chemical feed at water and wastewater treatment plants. While these all-in-one metering pump solutions bring tremendous value to their users, traditional platforms have their pitfalls.

Capacitive Deionization Takes Off Capacitive Deionization Takes Off

Capacitive deionization (CDI), sometimes called electrochemical demineralization, is referred to as Radial Deionization (RDI) by Atlantis Technologies, which has developed a proprietary form of the process. If you haven't heard of it by any name, or would like to know more about its considerable treatment capabilities, tune into this interview with Patrick Curran,

The Expanding Role Of Ozone The Expanding Role Of Ozone

As water reuse becomes increasingly common, more utilities will get to know ozone. To explain its role in water treatment schemes, Water Talk welcomed Jim Lauria, Vice President of Sales and Marketing at Mazzei Injector Company, and Ben Kuhnel, Senior Project Manager for Arcadis. Learn how ozone works in concert with other processes to safely recycle water and treat contaminants of emerging concern — even in mobile/on-site applications.

A Fresh Look At Membrane Bioreactors A Fresh Look At Membrane Bioreactors

Membrane bioreactors (MBRs) are not new, but they are the subject of renewed interest among utilities, and for Carollo Engineers Vice President Andrew Gilmore. He sat down with Water Talk's Todd Schnick and Kevin Westerling to discuss the MBR renaissance and the reason for their rise in popularity.
