  1. Oldest Town In West Virginia Adopts Modern Wastewater Treatment System 3/6/2014

    As with many of today’s aging plants reaching 30+ years of service, the outdated technology and in-efficiencies had placed a burden on a West Virginia town and its officials. The system was no longer able to accommodate the community’s growth or meet the effluent requirements on nitrogen and phosphorus.

  2. Optimized Purity And Recovery Of A Monoclonal Antibody Using Mixed-Mode Chromatography Media 10/3/2016

    Monoclonal antibodies (mAbs) remain a predominant class of therapeutic protein products on the market because of their wide range of applications in disease treatment and diagnosis. Over the years, upstream technology advancements have helped improve the titer of target antibodies, from merely 1 g/L two decades ago to 10–13 g/L in fed-batch processes and up to 25 g/L in perfusion cultures today (Gronemeyer et al. 2014).

  3. Identifying Contaminants Of Concern 1/28/2025

    In this article, we outline the sources, occurrence, known health issues, and mitigation options for specific contaminants.

  4. Water Authority Deploys More Efficient Solution For Now And The Future 7/16/2020

    Following the Reduction of Lead in Drinking Water Act announced by the Environmental Protection Agency (EPA) in 2013, Water Authority of Dickson County decided to look beyond its current metering manufacturing company and evaluate other solutions in the market. Leaders from WADC began conversations with their counterparts across Tennessee to find new, longer-lasting and more accurate meters, as well as a solution that would help WADC more strategically detect leaks and efficiently manage its time.

  5. Orientation Effect: Addressing A Food Metal Detection Challenge 6/3/2020

    Foreign objects such as small, oblong metal pieces like wires and pins exhibit “orientation effect,” a phenomenon in which the signal the metal detector sees is largely dependent on the contaminant’s alignment in relation to the detector’s aperture.

  6. Outfitting The World's Largest And Greenest Wastewater Treatment Plant 10/15/2015

    The sprawling Blue Plains Wastewater Treatment Facility is the largest advanced wastewater treatment plant in the world, with a capacity to treat an average of 370 million gallons of sewage a day.

  7. LCRI Updates, Insights, And Tools To Tackle Your Compliance Programs 3/5/2024

    With the recent release of the Lead and Copper Rule Improvements, and less than 9 months to submit your preliminary inventory, 120Water is unpacking what water utilities need to know to get the job done right - and on time.

  8. MBBR System Implements Nitrogen Reduction Plant Improvements 5/3/2019

    Hopewell Water Renewal (HWR) is a 50 MGD secondary wastewater treatment plant that treats the wastewater from local industries and domestic sources of the Hopewell, VA area. The plant began operating in 1977 and treats approximately 85% industrial waste. The facility achieves the treatment permit requirements for both BOD and TSS; however, treatment regulations have changed over the years and now require the removal of nutrients. HWR discharges effluent into Gravelly Run, a tributary of the James River and Chesapeake Bay Watershed.

  9. Reduce Lifecycle Costs For BNR With A Phased Activated Sludge System 10/18/2017

    Many wastewater utilities are under regulatory mandates to reduce effluent nitrogen and phosphorus. When trying to determine the best method for biological nutrient removal (BNR), lifecycle costs are an important factor.

  10. Real-Time Heavy Metal Monitoring For Oil & Gas 3/25/2021

    Large, distributed water networks are not well-suited for conventional water monitoring processes which rely on manual sampling and lab testing. In particular, this midstream oil and gas company had a need to detect Iron, Selenium, and other heavy metals at a precise level comparable to a lab. In addition, it wasn’t feasible to manually test the entire water system at the requisite frequency. Finally, instrument reliability and unplanned downtime were an issue.
