    Preparing For The Worst

    No utility wants to enact an emergency plan, but every utility should have one in place.

  • Less And More: Biological Nutrient Removal With Granular Sludge
    Less And More: Biological Nutrient Removal With Granular Sludge

    Many wastewater treatment plants (WWTPs) are facing stricter limits on nutrient discharges, yet each plant and situation is different and solutions are not one-size-fits-all. Bryce Figdore, Wastewater Process Engineer with HDR and Water Talk podcast guest, talks about another tool at utilities' disposal — nitrification bioaugmentation using granular sludge.

  • Laying The Blueprint For 'One Water' Management
    Laying The Blueprint For 'One Water' Management

    Partnering with the Water Research Foundation, Brown and Caldwell has developed the Blueprint for One Water — a user-friendly document for the practical application of 'One Water' planning. According to Lisa Skutecki, Brown and Caldwell's Southern California Water Resources Group Manager, 'One Water' is the concept of breaking down barriers across the water sector.

  • Green Energy And Decentralized Water Treatment For The Caribbean
    Green Energy And Decentralized Water Treatment For The Caribbean

    Among water treatment industry professionals, consensus is growing that small- to medium-scale decentralized desalination and wastewater treatment plants are the way forward in a water-stressed future. But governments continue to announce new water mega-infrastructure projects at an alarming rate. Because the public policy debate appears to have simply not caught up with current technology, many companies and NGOs with a focus on small- to medium-scale water treatment or renewable energy have begun to see the Caribbean as something of a new frontier.

  • The Expanding Role Of Ozone
    The Expanding Role Of Ozone

    As water reuse becomes increasingly common, more utilities will get to know ozone. To explain its role in water treatment schemes, Water Talk welcomed Jim Lauria, Vice President of Sales and Marketing at Mazzei Injector Company, and Ben Kuhnel, Senior Project Manager for Arcadis. Learn how ozone works in concert with other processes to safely recycle water and treat contaminants of emerging concern — even in mobile/on-site applications.

  • What's Next For Water Reuse?
    What's Next For Water Reuse?

    Steve Katz, Market Development Manager at SUEZ, explains how water reuse is being looked at differently today than it was even five years ago. Meanwhile, the stresses on water supply — increasing demand from industry and population growth, often in the face of drought — become more pressing with each passing year. Fortunately, water reuse is on the rise as public perception shifts and treatment technology advances.

ROMAG™ CSO Screen ROMAG™ CSO Screen

The ROMAG RSW CSO Screen, fitted between the discharge culvert and the relief sewer, reliably retains all visible solids during peak events.

Monster Wash Press Monster Wash Press

JWC Environmental’s Monster Wash Press (MWP) cleans and compacts the discharge from headworks screens, separating water and organics from the solids.  It features a Muffin Monster® grinder to pre-condition screenings before entering the Monster Wash Press.  The grinder breaks open rags, plastics and trash to promote washing and removal of soft organics.  The patent-pending paddle rotor in the active wash zone agitates the material to enhance water penetration throughout the debris for even better removal of the organics from the solids.  Organics are washed back into the wastewater treatment process and the solids are compacted into a dry, less odorous solid plug.  The Monster Wash Press is designed for easy maintenance.  The rotor and field replaceable screen can be removed via the top of the unit, minimizing the clearance space needed around the unit during maintenance.  A grinderless version of the Monster Wash Press is also available.

PASSAVANT® Disc Diffuser ROEFLEX® PASSAVANT® Disc Diffuser ROEFLEX®

The disc diffuser ROEFLEX® stands out for its simple and robust design. It consists of a unique, convex shaped support disc. The disc is covered by a flexible, slotted membrane of elastomer, a ring secures the membrane in place. Due to the disc’s unique convex shape the membrane is slightly lifted off the disc when air is supplied, therefore allowing an even distribution of the generated fine bubbles. The membrane can be delivered in different rubber (EPDM) qualities and slot patterns (HL, SL) according to the application.

NIROBOX™ SW NIROBOX™ SW

Containerized seawater desalination solutions ensure water availability in a wide range of applications.

ABB Ability™ For Water Desalination ABB Ability™ For Water Desalination

100% available water in the driest of deserts through highly efficient desalination.

    DC Water’s Unconventional Approach To Utility Management

    Over the past 10 years, DC Water has become the harbinger of the modern water utility. It’s often unconventional approach to tackling age-old problems usually elicits one of two responses from other utility professionals. The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.

  • Pulling Together: Public-Private Partnerships Poised To Push California Water Efficiency
    Pulling Together: Public-Private Partnerships Poised To Push California Water Efficiency

    California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.

    What Happens To The Chesapeake Bay Now?

    One of the great turnaround stories in the history of our nation’s water bodies is that of the Chesapeake Bay. Since 1976 when the Environmental Protection Agency (U.S. EPA) first undertook a comprehensive study of the Bay, efforts to address excessive nitrogen and phosphorous degradation of water quality have steadily improved the Bay’s complex ecosystem.

    Hydrant Humor: Tales From The Field

    District Sales Engineer Andy Singer has spent enough time troubleshooting problems in the field that not much surprises him anymore. When it comes to dry barrel fire hydrants, though, he still gets a chuckle out of some of his more outrageous experiences. Here is his educational and entertaining take on the care and maintenance of fire hydrants, and ways to maximize a utility’s return on what potentially can be a 50+-year infrastructure investment.

    Now that you have returned to the role of private citizen — though, admittedly you are a private citizen with millions of eyes focused on you — I want to encourage you to continue your great work promoting the health of our nation’s children. Your emphasis on exercise and nutrition, jobs and support for veterans, and education have touched millions of Americans of all ages and all backgrounds. Now it’s time to bring in the most common denominator and the first step toward good health — access to clean water.
