  • Fountain Valley, California Beats Water Reduction Goal With Sensus Technology
    Fountain Valley, California Beats Water Reduction Goal With Sensus Technology

    Dried up reservoirs, cracked dirt and empty swimming pools are just a few of the visual reminders of the ongoing California drought. But what most people don’t see is the water providers, like Mark Sprague at the City of Fountain Valley, working tirelessly to keep the water running.

  • Super Centurion® A-459 Urban Fire Hydrant Datasheet

    The Mueller® Super Centurion A-459 fire hydrant provides multi-directional access to emergency water in busy urban settings where vehicles aren’t always parked where they should. Featuring two pumper and two hose nozzles, first responders can quickly connect to all sides of the hydrant.

  • UV Small Footprint And Flexible Hydraulics Makes Space For The Future
    UV Small Footprint And Flexible Hydraulics Makes Space For The Future

    When a piece of process equipment needs to be replaced, it is tempting to go with a straight replacement in kind – same manufacturer, same model, just the latest version of “the same”. But often, full consideration of other options opens new possibilities for your treatment plant. That was certainly the case for Plainfield, Indiana.

  • Multi-Point Chlorination Process To Treat Raw Water Yields To A Multi-Barrier Chain Of Treatment Technologies
    Multi-Point Chlorination Process To Treat Raw Water Yields To A Multi-Barrier Chain Of Treatment Technologies

    For decades, a Winnipeg utility used a multiple point-chlorination process to treat raw water drawn from remote Shoal Lake. Concerns eventually arose about the potential presence of chlorine-resistant pathogens–Crytosporidium and Giardia–and residual disinfection byproducts, which coincided with encroaching development near the lake. The Clari-DAF system was selected and now removes 70 percent of the organics at the Winnipeg plant, which also improves filtration and extends the intervals between filter backwashes.

  • Top 10 Questions You Should Ask When Purchasing A Control Valve
    Top 10 Questions You Should Ask When Purchasing A Control Valve

    Automatic control valves, much like everything else we purchase these days, are not all created equal. Some fall into the high quality bracket with pricing to match, while others hover closer to the lower quality and price sensitive end of the scale. Unfortunately, when evaluating control valve prices, it is not always clear what you are being offered and what standards the valve actually meets. Here are a few questions to consider and ask the supplier to ensure you get years of trouble free operation that lasts longer than it takes the sales person to drive out of your parking lot!

  • An Independence Day Salute To Our American Heroes
    An Independence Day Salute To Our American Heroes

    Last month I tipped my hat to America’s rural water districts in the blog post Rural Water Systems: Dancing Backwards and in High Heels. As Americans prepare for Independence Day, it’s a perfect time to salute some truly unsung American heroes: the people who operate our nation’s drinking water and wastewater treatment plants.

  • Achieving Ultrapure Water
    Achieving Ultrapure Water

    It may sound intimidating, but water that has been treated to “ultrapure” condition is more than necessary in many applications. This highly-cleansed product is a fundamental part of many industrial operations, from the medicine we need to get well to the power we rely on in our daily lives. But, as the name implies, it’s no small task to get average influent to the ultrapure level.

  • The Climb To The Top
    The Climb To The Top

    Back in the late 1980s when market drivers created the cost-effective option of using above-ground circular tanks for industrial activated sludge processes, there were some early valuable lessons for both aeration equipment manufacturers and plant operators.

RSS Externally Fed Drum Screens RSS Externally Fed Drum Screens

Self-Cleaning Wedgewire Screen
The RSS Externally Fed Drum Screen is a reliable self-cleaning screen for both municipal wastewater operations as well as many industrial applications. This screening technology performs particularly well in wastewater with high oil or grease loadings as well as scum applications that can blind other types of screens.

ETS-UV™ For Water Reuse ETS-UV™ For Water Reuse

Given the critical shortage of drinking water in many regions, advanced treatment and reuse of wastewater is becoming increasingly common as municipalities address water demands and shrinking supplies.

Ultraviolet Disinfection ETS-UV™ Systems Ultraviolet Disinfection ETS-UV™ Systems

Ultraviolet (UV) irradiation is used for multifunctional purposes.  UV is most commonly used as an environmentally friendly alternative to chemical disinfection. It’s one of the most effective methods for inactivating harmful pathogens such as Listeria, E.coli, Giardia and chlorine tolerant pathogens like Cryptosporidium.  UV is also used for removal of organic and inorganic contaminants, including chlorine, ozone and Total Organic Carbon (TOC).  UV used in conjunction with an Advanced Oxidation Process (AOP) will remove Compounds of Emerging Concerns (CEC's), Synthetic Organics (SO's), Endocrine Disruptor Compounds (EDC's) and Personal and Pharmaceutical Care Products (PPCP's), as well as various taste and odor compounds from water.

    Why California's Cannabis Industry Will Lead Water Innovation

    For years, I’ve been standing on my deck in San Francisco, looking south to Silicon Valley for innovation in water efficiency. But I’m starting to realize that I might have been gazing in the wrong direction. Maybe I need to turn around and look north, over the spires of the Golden Gate Bridge, toward the Emerald Triangle in Humboldt, Mendocino and Trinity counties, the hotbed of California’s newly legalized commercial cannabis production.

  • Lessons Learned From Flint
    Lessons Learned From Flint

    We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly  desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.

    ORP Sensors – Are They Really The Best Thing “Since Sliced Bread”?

    There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.

    When is the last time you took a moment to stop, and smell your water? A continuous supply of clean and safe drinking water is something that most people take for granted. We rarely go to the tap doubting that the water will be clean and safe. Recently, the general population and water supply professionals have become concerned about the safety and protection of our drinking water supplies.

  • How To Ensure Your Utility Complies With The LT2
    How To Ensure Your Utility Complies With The LT2

    The U.S. EPA’s Long Term 2 Enhanced Surface Water Treatment Rule (LT2) was adopted in 2006 to modify the Safe Drinking Water Act and more tightly control the spread of Cryptosporidium, a microorganism that can cause gastrointestinal infection if ingested. Since its inception, the rule has posed a treatment challenge to utilities that are susceptible to the tiny contaminant. But which utilities are at risk? And how should they approach treatment?

  • Preparing For Algae Season
    Preparing For Algae Season

    For water treatment operators and utility officials, the summer months don’t just mean sunshine, pool parties, and barbecues. The season also brings the peak time for algal blooms, the toxic clouds formed in surface water thanks to increased nutrient contamination and rising temperatures. With rising instances of toxic algae around the country and increased regulations for eliminating it, utilities have had to keep pace.
