Water Industry Features, Insights, & Analysis

  1. WWTP Air Handling Control Philosophies: Do’s And Don’ts
    3/9/2018

    Without an appropriate control strategy, even the best wastewater treatment plant (WWTP) equipment can struggle to deliver maximum efficiency. Because energy costs represent up to 60 percent of WWTP plant operating expense, air distribution designs and changing loading (biochemical/biological oxygen demand [BOD]/chemical oxygen demand [COD], ammonia) demands require control strategies designed to adapt to all eventualities efficiently. The following checklists, plus important Do’s and Don’ts, can help in identifying an underperforming control strategy and developing a better one.

  2. A Visual Guide To Troubleshooting Your Valves
    1/9/2017

    Water management professionals know all too well that problems arise — usually sometime after 2 a.m., or just as you’re walking out the door for a holiday weekend. No matter how well-prepared you are, or how sophisticated your system, sometimes you’re going to run into challenges. It’s simply the nature of the industry. When you experience an issue with your valves (especially when they’re failing to open or close as expected) your first instinct is to call the factory for support. While some cases may require factory assistance, this isn’t always the most efficient solution.

  6. Integrated Communication Apps: Get Employees On The Same Page
    2/13/2018

    The collaboration and communication tech markets are inextricably linked—at least in terms of how business users expect them to operate. It’s the vendors that tend to be miles apart, which can cause pain for users. I covered the distinction between communication and collaboration in a previous blog with this key takeaway; you can collaborate all day long but unless you communicate in real-time, productivity takes a hit and things can very quickly start to break down. That’s why it’s so important for these two functions to be connected through technologies like integrated communication apps.

    10/2/2017

    Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.
