WASTEWATER MEASUREMENT RESOURCES

  • The instrumentation supervisor for the City of Baltimore, MD’s 150-MGD Back River wastewater treatment plant (WWTP) reports that replacement of problematic vacuum feeders with more advanced vacuum feed units has ended heavy maintenance burdens associated with sodium hypochlorite (hypo) treatment of plant effluent.

  • The City of Houston Public Works engaged Optimatics, Tetra Tech, and WCS Engineering to develop solutions to eliminate CSOs within a section of their sewer network. This optimization effort focused on developing solutions to eliminate CSOs in the catchment area upstream of the Eddington lift station, located to the southwest of Houston’s downtown area. As part of previous work targeting these CSOs, the City had designed a capacity upgrade for the Eddington lift station.

  • The City of Memphis teamed with Brown and Caldwell to pilot a smart sensor network where water-quality monitors could be installed directly at permitted discharge points for five of the largest industrial users. The pilot project also served as a proof-of-concept project for the City to assess the feasibility of making a paradigm shift to digital water-quality monitoring as a long-term solution.

  • If AI can inform decisions, can it also help execute them? For the water sector, this distinction is not just semantic; it is the difference between a digital assistant that takes notes and a digital operator that turns valves.

  • Water Online’s “Math Solutions” series, presented by wastewater consultant and trainer Dan Theobald (“Wastewater Dan”), provides an understanding of the sometimes difficult calculations involved in achieving wastewater operator certification.

  • Flush and forget? Not if you have a toilet that flushes to one of over 3,000 sites around the world where researchers are using wastewater to track SARS-CoV-2, the virus that causes COVID-19. But what do members of the public actually know about wastewater surveillance? And what do they think about researchers tracking what they send down the drain at their home?

  • Thames Water worked with eight20 and Optimatics to investigate whether changing dynamic valve settings and installing additional booster pumps to service tall buildings could help reduce leakage losses within their networks.

  • With electricity prices climbing each year and eating up a greater share of companies’ operating expenses, energy efficiency is rightly becoming a top priority for many municipalities and businesses. According to the U.S. EPA, drinking water and wastewater treatment plants account for about 30 to 40 percent of many municipal governments’ total energy consumption.

  • When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.

  • 300,000 square feet. That was the size of the tradeshow floor at WEFTEC, the world's largest annual water quality exhibition. I didn't see every technology showcased last month in New Orleans (over a thousand exhibitors were on hand), but here’s a “best of” list from the many that I came across — a snapshot of various technologies that stood out from the masses, exceptional for their level of innovation and potential for industry impact.

WASTEWATER MEASUREMENT SOLUTIONS

  • SLIC Traditional SCADA

    SLIC is the first control system that doesn't need a SCADA server, control panel, integrator, or a babysitter.

  • wastewaterOS

    wastewaterOS unifies costs, data, maintenance, training, lab results, and automation into one AI-driven platform. It doesn't just monitor; it runs your plant smarter. 

  • MD50 COD

    The MD50 COD is a next generation compact, single parameter photometer for the measurement Chemical Oxygen Demand (COD). The MD50 is an advanced successor to the MD100 COD photometer, offering improved accuracy, enhanced user experience, and expanded testing capabilities. 

  • TB350

    Ideal for field and environmental testing, the TB 350 turbidity meter delivers the most reliable measurements for low range to high range samples without sacrificing accuracy.

  • MD50 Chlorine Colorimeter, LR/HR

    The MD50 Chlorine LR/HR Colorimeter combines a simple user interface with advanced optics to deliver the accurate and reliable results municipal and industrial users require - and packs a lot of features into a rugged, hand-held instrument.
