    Extreme Water Filtering – Consider High-Flow Systems To Save Costs And Reduce Waste

    In an era when everything is done to the extreme – from sports, to home makeovers, to weather predictions – it should come as no surprise that the world of water filtering has joined the crowd. “Extreme” filtering, so to speak, is achieved through the use of high-flow cartridge systems – smaller designs that are able to handle much higher water volumes and pressures at lower costs and with less maintenance. By Robert LeConche, President, Shelco Filters

    Hybrid Blowers: Should WWTPs Believe The Hype?

    In 2010, an energy analysis of the Freeport Wastewater Treatment Facility in southern Maine revealed that the plant had significant inefficiencies in usage. Specifically, the plant’s 30-year-old multistage centrifugal aeration blowers were accounting for as much as 90 percent of electricity consumption.

  • Multi-Barrier Disinfection Strategy - New York City (Case Study)
    Multi-Barrier Disinfection Strategy - New York City (Case Study)

    New York City is home to more than 8 million people, making it the most populous city in the United States. The majority of New York's drinking water is supplied by the Catskill/Delaware watershed, located approximately 100 miles outside the city. Historically, NYC has not filtered the water from this system, nor did they require any additional barriers to microbial contaminants due to the pristine nature of the watershed.

  • Utility Improves Data Accuracy, Customer Service With Advanced Metering Analytics
    Utility Improves Data Accuracy, Customer Service With Advanced Metering Analytics

    Bethpage Water District’s (New York) outdated water metering system led to customer service concerns, such as a slow response time for detecting leaks and insufficient data for billing inquiries. By installing new meters and advanced metering analytics software, the district increased visibility into its operations, resulting in greater revenue and improved customer service.

  • Shed The Lead

    When is a water meter truly “green”? In addition to meeting lead free regulations, it should also provide utility users with recyclability, field-proven durability – and just as important – superior scrap value at end of life. This video examines how traditional lead-free bronze-body meters offer all of the above – something that cannot be said for non-recyclable plastic or composite water meters.

  • QuadraTherm® 640i/780i Mass Flow Meter Datasheet

    Traditional thermal sensors have two sensors-–one temperature sensor and one velocity sensor, each in a separate probe sheath. QuadraTherm (the term “Quad” meaning “four”) introduces four sensors—three precision platinum temperature sensors and one patented DrySense mass velocity sensor. Sensor performance improvements never thought possible are gained with QuadraTherm as forced convection is completely isolated (the critical variable for measuring gas mass flow rate) by calculating and then eliminating unwanted heat-transfer components, like sensor stem conduction, one of the major causes of false flow readings.

    Looming In The Sewers: Nonwovens Are Weaving A Tangled Web

    Looming in the world’s sewer system are contaminants of emerging concern.  They’re not the endocrine disruptors, antibiotics or painkillers we’ve been reading about for the past several years (though those are indeed a challenge).  These contaminants are bigger, and like the legendary alligators rumored to lurk in the New York City sewer system when I was a kid, they are growing steadily, day by day, to pose a catastrophic threat.

    In California, Come Rain Or Shine, Upfront Efficiency Is Always In Style

    Caught between a withering drought and floods from winter storms, California faces the worst of both worlds—dealing with scarcity as well as stormwater.  America, and much of the world, is watching to see how this trendsetting state handles those challenges.  After generations of setting America’s style, from cowboys to Beatniks to Beach Boys to Silicon Valley billionaires, California can set perhaps its most important trend yet—it can lead the way to a more water-efficient America.  It has to.  The good news is that it can.

    These days, operators and managers of water treatment plants are losing sleep. Why? Because they may be losing water.

  • Activated Carbons As A Solution To Emerging Pollutants

    The presence of active pharmaceutical ingredients, radio-opaque substances, and endocrine-disrupting chemicals in raw water sources has caused concern with regards to their concentration level in drinking water. A study for the removal of these micro-pollutants was recently conducted at a full-scale water production plant in southern Germany. This technical bulletin presents the study results and explores the role of activated carbons in the efficient removal of these substances from water.

  • Capacitance Level Switches Provide Reliable Water/Oil Interface Detection
    Capacitance Level Switches Provide Reliable Water/Oil Interface Detection

    There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.
