  1. 15 Steps To Identifying Your Best WTP & WWTP Flow Metering Options
    10/22/2018

    There’s a lot to be said for the old adage, “Use the right tool for the job.” When it comes to flow meters for municipal or industrial water treatment plant (WTP) and wastewater treatment plant (WWTP) operations, however, the sheer number of choices can be overwhelming. That is where using a process of elimination to winnow out styles that don’t fit the performance criteria of an application can make it easier to compare the few remaining options. Here is a checklist of considerations to accelerate that process.

    When emergencies inevitably arise, municipal operators need to be prepared to respond immediately to restore services in order to provide safe, reliable water to their customers. Take for example the City of Cisco, Texas.

  3. RTC‐ST Reduces Polymer And Increases Biogas Production

    Hach’s off‐the‐shelf Real-Time Control System for Sludge Thickening (RTC‐ST) adjusts the sludge thickening process in real time. Thanks to the RTC-ST, a wastewater treatment plant improved thickened sludge consistency and gas production while reducing money spent on excessive polymer dosing and maintenance.

  4. Becoming A “Water Resource Recovery Facility” Offers Financial Benefit
    8/4/2016

    While the term “Water Resource Recovery Facility” may seem like nothing more than a trendy phrase, the name change represents a distinct shift in the role that wastewater utilities can now play.

  5. Plant Operations And Maintenance Staff Benefits From New Headworks
    2/1/2017

    The high cost of maintenance and unsatisfactory performance of the aging equipment in the Bonnybrook headworks made it clear that significant changes were in order. The older poorly performing headworks allowed screenings to pass to the downstream process units causing operational and maintenance problems. By installing the Huber RakeMax® and matching WAP washpress, Calgary’s process performance immediately improved.

  6. Emergency Chlorine Scrubber Refurbished After Inspection Reveals Serious Problems

    In December 2006, Integrity Municipal Services (IMS) was contacted by the City of California City Plant Manager Greg Fielding to perform an inspection of their RJ-2000® emergency chlorine vapor scrubber system.

  7. Meeting Stringent Discharge Levels With AccuFAS

    When the Coldwater Board of Public Utilities in Coldwater, Michigan abruptly received new ammonia permit limits in August of 2007, they hired consultants to help guide them to the best solution for their new problem. With a full‐measure of influent waste variety consisting of residential, commercial, industrial and septage and a new seasonal permit limit of 2mg/L, Coldwater hoped for a budget friendly solution to consistently perform through peak flows and industrial shockloading.

  8. Refinery Expands Production While Meeting Discharge Standards Quality
    8/5/2016

    Petron Bataan Refinery wanted to expand production to process 180 thousand barrels of crude oil per day while changing its feedstock from Arab Light to less costly heavy and sour crudes.

  9. Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility
    5/1/2017

    The North Columbus Resource Facility recently completed a $12-million replacement of its settled water filtration, removing the existing Wheeler filters, their three-part media and 10-inch poured concrete underdrains, which were no longer efficient.
