51. What Water Utilities Need To Know About Climate Adaptation 9/18/2025
    No one knows more than water utilities how changing climate conditions are impacting the challenges and costs of delivering clean drinking water to communities they serve. In a recent episode of The Water Online Show, climate experts Jesse M. Keenan from Tulane University and Edgar Westerhof of Arcadis discussed the issue of resiliency for drinking water and wastewater systems.
52. Beyond The Concrete: How Packaged Headworks Solve Modern Wastewater Challenges 9/17/2025

    Packaged headworks systems provide flexible, high-quality screening for wastewater applications, offering fast installation, modular design, and low maintenance—ideal for temporary projects, small facilities, or specialized industrial sites.

53. Circularity And Risk Management In Semiconductor Manufacturing 9/17/2025
    Reclaimed water from semiconductor fabs may serve non-process users or even re-enter production via ultrapure water (UPW) recycling to reduce incoming water demand. But what happens when things go wrong? If the UPW system cannot handle variations in reclaimed water quality, costly treatment measures or quality failures ensue.
54. Water Tank Helps Solve Colorado Community's Water Woes 9/15/2025

    Many Colorado communities are wrestling with an ongoing water crisis. The problems are extensive — climate change, drought and increased demand and other factors have played a role in severe shortages, which have challenged residents since the turn of the century.

55. Droughts Don't Just Dry Up Water — They Drain Livelihoods And Weaken Local Economies 9/15/2025
    Droughts hit utilities and agriculture hardest. Shrinking water supplies wilt crops and strain water providers. But the impact extends far beyond them.
56. New Monochloramine Sensor Technology Measures Free Chlorine And Total Chlorine On The Same Sensor 9/12/2025

    Traditional chloramine monitoring methods have drawbacks that complicate water treatment. A new sensor can measure multiple parameters, offering operators better process control.

57. How Can We Create A More Effective Densified Sludge? 9/11/2025

    True densified sludge, achieved with time-based batch controls, improves settling, increases capacity, and enhances nutrient removal—delivering a compact, efficient, and cost-effective alternative to conventional activated sludge systems.

58. Advancing Wastewater Treatment Through Specialized Bioaugmentation Solutions 9/11/2025

    Read about how new anaerobic treatment products address critical challenges in digester performance and biogas production.

59. The Role Of Turbine Flow Meters In Wastewater Treatment Plants 9/10/2025
    Wastewater plants are made up of a series of interconnected processes, each one dependent on accurate data. Turbine flow meters can be installed at several stages to provide operators with real-time, trustworthy flow information.
60. Constant vs. Proportional Diffusivity In RSSCT: Choosing The Right Model For GAC Performance Testing 9/9/2025

    When designing adsorption systems for PFAS removal, utilities and engineers increasingly rely on RSSCTs (Rapid Small-Scale Column Tests) to compare the performance of granular activated carbon (GAC) or other sorbents. One often overlooked yet critical assumption in RSSCT modeling is the choice between constant diffusivity and proportional diffusivity. Though both approaches are valid, selecting the right model can significantly impact how well bench-scale results translate to full-scale systems.
