  1. FILTRASORB 400 Provides PFAS Solution For Air Force Base In Interior Alaska
    10/23/2019

    When Eielson Air Force Base, located in the interior of Alaska, found high levels of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in their drinking water, they needed a solution that was effective, cost-efficient, and operable in extreme temperatures. Calgon Carbon’s Model 10 adsorption system, filled with FILTRASORB 400 granular activated carbon (GAC), was determined to be the best option.

  2. Water Treatment Filter Monitoring

    A municipal water utility follows a straightforward method for providing clean water to its residents: It pulls water out of a nearby river, filters out the impurities, and then funnels the water into a reservoir to be ready when residents turn on their taps. The water provider needed to improve sand filter consistency and boost performance of its overall fleet of filters in its water treatment plant. To do this, it needed to identify and monitor for poor filter performance while prioritizing filter maintenance.

  3. Not All Differential Pressure Meters Are Created Equal
    10/21/2019

    Due to the dynamics of liquids and gases flowing through elbows, valves, pumps, and other pipeline structures, every flow-meter methodology has its own design limitations. Unlike Venturi meters, pitot tubes, orifice plates, and other devices, V-Cone meters provide highly accurate and reliable readings with minimal straight-pipe length restrictions and virtually no maintenance, in pipe sizes up to 120”.

  4. Optical Oxygen Sensors Promote Efficiency Gains
    10/18/2019

    Tight control of the biological process in aeration basins is the lynchpin of wastewater treatment at municipal facilities. To perform at their peak, the “bugs” in these basins require a specific amount of oxygen. However, the air blowers controlling this process consume a significant amount of energy and thereby represent a major expense. Now, advanced solutions are available that provide a cost-effective method to measure the oxygen for automatic control in the basins without the need for frequent maintenance.

  5. Dangerous Waters In A Changing World
    10/15/2019

    Americans and Canadians got a peek into the future when the City of Toledo shut its drinking water taps in 2014, issuing a do-not-drink order on the municipal water supplies serving 500,000 people. Levels of microcystin, a potent liver toxin produced by blue-green algae, were more than double the World Health Organization's safe limit. More than 700 square miles of the Lake Erie surface was covered by a harmful algal bloom (HAB), and drinking water plants couldn't remove the algal cells and the toxins they produced.

  6. Plastic Flow Meters Reduce Weight, Space, Corrosion — Not Accuracy
    10/11/2019

    There are a variety of reasons for wanting accurate flow metering — e.g., billing purposes, precise proportioning of chemical injections, and other process flow decisions. That is why highly accurate mag meters are so popular in many applications. Now, new lightweight, corrosion-resistant mag meters provide the same advantages as plastic piping for harsh environments and flows that cover all the bases…and acids.

  7. A New Era In Blower Control Efficiency
    10/10/2019

    A common misconception among wastewater plant managers is that pressure-based blower controls remain an industry “best practice” for aeration. The problem is this approach was developed during an age when most blowers were constant speed machines with outputs that could only be governed by the manipulation of inlet valve position or header pressure. Newer self-tuning, airflow-based control systems save energy, improve effluent, and reduce greenhouse gas emissions.

  8. Keys To Tackling Industrial PFAS Treatment
    10/10/2019

    While municipalities have been working for several years to address per- and polyfluoroalkyl substances, commonly known as PFAS, a growing number of industrial operations are being prompted to treat their wastewater and stormwater for the contaminants. While any steps taken to reduce PFAS are positive, performing a thorough investigation before selecting a solution is critical to getting the best results at the lowest cost.

  9. Navigating The Partial-Pipe Flow Challenge
    10/10/2019

    One of the most perplexing challenges that wastewater plant operators face is the need to measure the various sources of influent. For closed-pipe systems, the use of traditional flow devices requires intensive and expensive engineering to keep the pipe full at the point of measurement. The good news is that there is an emerging solution that measures flow in a less-than-full pipe.
