    Following one of the driest periods on record in California, farmers in the San Joaquin Valley faced restricted water allocations.

  2. Flow Data Red Flags: When To Act
    12/20/2017

    Accurate flow measurement is critical to most water and wastewater processes. Red flags may pop up to indicate meter problems, but which ones should lead you to act — and when? The answer depends on the type of meter, what it is used for, and whether the readings are local or remote.

  3. Clearing Channels And Tanks Of Rag And Fiber Produces Benefits Beyond The Tanks
    11/20/2017

    Reduction of ragging is merely one of the benefits the EscaMAX® Perforated Plate Screen bestows upon its implementer. But this is such a huge factor, that mitigating it brings night-and-day results in other areas such as reducing debris in the grit channel, increasing space for energy-producing biosolids in tanks, and releasing cleaner end products.

  6. Top 10 Considerations When Converting To On-Site Hypochlorite
    12/26/2013

    Transporting pure salt - the raw material needed to generate sodium hypochlorite onsite – is more cost effective, stable, and safer, than transporting and storing bulk sodium hypochlorite, or gaseous/liquid chlorine cylinders from local chemical suppliers. The conversion to on-site hypochlorite generation can be achieved by adhering to these design guidelines.

  9. Harmful Algal Blooms – What’s In Your Drinking Water Intake?
    7/18/2017

    In August 2014, the city of Toledo, Ohio informed its residents (~500,000 people) that they should not use tap water for any purposes including bathing and cooking. The culprit: microcystin, a toxin produced by blue-green algae, had been detected in the city’s finished drinking water at concentrations 2.5 times the World Health Organization’s guideline value.
