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...  Continue Reading..
Using Fingerprints To ID Ideal Instrument Performance
Everyone wants peak accuracy from their instrumentation, but nobody wants to disrupt their field process to verify it. Purvang Upadhyay, the global water industry manager for measurement and analytics with ABB, shared an attractive alternative to such disruption with the Water Talk moderators at WEFTEC 2019 — in-situ verification. This classic example of digitalization in the water industry enables users to check the health and accuracy of...  Continue Reading..
Improved Intelligence For Better Control
The water and wastewater industry has been dominated by automation based on programmable logic controllers working in tandem with SCADA. However, newer systems that better blend those aspects provide improved intelligence. As a result, plant operators aren’t required to maintain a separate engineering station to control strategy as well as the HMI.  Continue Reading..
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...  Continue Reading..
Anaerobic Digestion Now Making More Biological/Financial Sense
Is there value in anaerobic digesters beyond wastewater treatment? According to Nick Bonkoski, a domain leader for anaerobic digestion systems at Suez Water Technologies, the answer is a resounding “Yes.” The insights he shared with Water Talk at WEFTEC 2019 paint a bright ecological and financial landscape of how municipal wastewater treatment plants now incorporate co-digestion of food waste with biosolids to capitalize on excess...  Continue Reading..
New STEPs Minimize Biosolids, Energy, And Installation Costs
When low population density and troublesome topography make traditional gravity sewers cost-prohibitive, septic-tank effluent-pumping (STEP) technology offers an affordable alternative. In this Water Talk discussion, Mike Saunders, market segment leader for engineered systems at Orenco Systems, outlines how to match the right technology to the need. Orenco’s new decentralized liquid-only sewer systems treat septic effluent that is reduced...  Continue Reading..
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.  Continue Reading..
Adapting To A New Era Of Food Processing
Many food processing facilities operating today were designed and built to accommodate consumer habits of a bygone era. As those commercial markets have evolved, and industry has adapted to the changes, the wastewater plants at those sites are no longer capable of processing the waste generated during production.  Continue Reading..
A Fresh Take On Biological Wastewater Treatment
Improving wastewater treatment efficiency requires some type of change in the physics, biology, or economics of the process. In this Water Talk interview, Jeff Kelly, Red Valve’s senior product manager for the Tideflex Aeration and Mixing System, describes how to change all three — to the tune of a cost-saving 50-percent reduction in applied airflow! The Tideflex approach uses a unique diffuser design to support on/off aeration and...  Continue Reading..
Cutting Sewage Problems Down To Size
For the past 10 to 15 years, wastewater treatment operators have faced increased clogging issues related to baby wipes, disposable diapers, rags, and other foreign debris. At the same time, the use of low-flow toilets has increased the solids concentration of sewage flow. This discussion with Brad Jernigan and Christina Foster from Pentair addresses differences between how grinder pumps (low flow/high head) and chopper pumps (higher flow/lower...  Continue Reading..
