1. Treating Contaminants Of Emerging Concern In A Variety Of Water Sources 8/13/2020

   Contaminants of emerging concern (CECs) can be a challenge throughout all stages of the water cycle. Here are some key considerations for water treatment plants (WTPs), wastewater treatment plants (WWTPs), and water reuse applications where removal of 1,4-dioxane or per- and polyfluoroalkyl substances (PFAS) is currently, or might soon become, a mandatory focus in their treatment train.

2. Planning For Total Resiliency In Fighting Contaminants Of Emerging Concern 8/12/2020

   In the constant flow of drinking water and wastewater treatment systems, operators have precious little time to skip a beat. When unexpected changes arise — such as being mandated to reduce contaminants of emerging concern (CECs) — the ability to maintain balance throughout the treatment process becomes a driving factor. For decision-makers faced with remaining resilient despite CEC concerns, here are some key points to consider.

3. Fight Contaminants Of Emerging Concern With A Pipeline Of Innovation 8/11/2020

   Water treatment challenges are never-ending — from source water availability, to seasonal upsets, to new contaminants of emerging concern (CECs). The best way to stay ahead of such issues is to cultivate a pipeline of innovative solution development ready to address the next challenge. Here are some key insights for evaluating suppliers that are best positioned to do exactly that.

4. Testing Better Paths To Contaminant Control 8/10/2020

   As a utility, it is tough enough to be notified that you need to remove a new contaminant of emerging concern (CEC). It’s even harder without having a complete picture of what is involved. For water treatment plants (WTPs) and wastewater treatment plants (WWTPs), here is how choosing the right testing regimen is essential to quantifying the degree of the problem and evaluating the optimum treatment alternatives.

5. Solving Pump Clogs Without Spawning A Million New Problems 8/7/2020

   With all the potential debris running through wastewater collection systems — including higher concentrations of “flushable” wipes than ever — the debate over chopping them to bits, or not, has become a fundamental question for wastewater utilities. Now, new perspectives and new mechanisms are giving wastewater treatment plant (WWTP) operators new opportunities for cutting the wipes problem down to size.

6. 'Series' Wastewater Pumping Solves Unique Challenge Of High Head Force Mains 8/6/2020

   In high-head wastewater pumping applications that result from long force mains or high-static heads from hilly terrains, lift station design engineers typically select oversized pumps that sufficiently overcome the inherent friction losses. However, a dramatic reduction in efficiency occurs at the pump operates far from its best efficiency point. In these situations, the use of vacuum-primed pumps arranged in series can achieve higher pumping efficiencies and lower resulting power costs.

7. Don’t Let Bad Customer Decisions Wipe Out Your Entire Treatment Train 8/6/2020

   Flushable wipes are wreaking havoc in collection systems and treatment plants around the globe. While this is not a new issue to those in our industry, COVID-19 has made it a mainstream topic as more households consume disinfecting and flushable wipes. The improper disposal of these down the toilet can have negative impacts on the operating cost and efficiency of an entire collection system and treatment train. Here is how nipping the problem at its source can pay dividends throughout the process.

8. Smart New Approaches To Wastewater Screen Design 8/5/2020

   Depending on the age and design of wastewater infrastructure, it is easy for screening performance at the headworks of wastewater treatment plants (WWTPs) to get caught between a rock and a hard place. With so many challenges, what can be done to reduce the high risks of performance inefficiency, costly maintenance, or outright equipment failure? Fortunately, next-generation bar screen designs are poised to address these issues.

9. Insta-Valve 20-24 Provides Needed Control For Infrastructure Expansion 8/4/2020

   Hydra-Stop’s solution allowed targeted control to connect a million-gallon water tank to a new water treatment center.

10. Challenges With Calibrating Electromagnetic Flow Meters 8/4/2020

    This article focuses on the use of electromagnetic flowmeters in the W/WW industry. It also covers Endress+Hauser’s capabilities to manufacture electromagnetic flowmeters from 1/12” to 120”, calibration, the company’s new innovative sensor with multiple sensing electrode pairs and verifying calibration in place after installation.
