    The sky is blue, grass is green, and, someday, your pumps are going to clog. It’s just another fact of life — or is it? 

  2. Retrofitting: Is It Right For Your Sewage Lift Station? 2/22/2017

    It’s just past 10:00 on a Friday night, and the phones start ringing in the pockets of the on-call collection systems operators. It’s an alarm for another pump clog at one of your sewage lift stations — the second one this week.

  3. Our Screens Work Great! Now What? (Part 3 Of 3) 9/22/2016

    This is the third installment of a three-part series exploring headworks screening problems and solutions. In this installment we will explore solids removal options for headworks facilities.

  4. The Fine Points Of Headworks Screening (Part 2 Of 3) 8/19/2016

    Protecting wastewater treatment facilities requires operators to think strategically about their unique challenges and identify the best solution for their specific requirements. Specifying the appropriate headworks system for the plant’s needs is arguably one of the most important design decisions a public works engineer will make.

  5. Outfitting Your Headworks Systems (Part 1 Of 3) 7/15/2016

    A plant’s headworks plays a crucial role in the pretreatment influent for any wastewater treatment facility. They protect the operation of downstream equipment and enhance the efficiency of the overall wastewater treatment process.

  6. How The Industry Can Take On Wipes In The Waste Stream – And Win: Part 3 9/23/2015

    As outlined in earlier articles, increasing public awareness or even seeking legal action are potential tools to help municipalities gain control of the wipes problem. However, many agencies have seen that these strategies are not completely effective in the long term, and they must also employ new technologies to permanently deal with the wipes epidemic.

  7. How The Industry Can Take On Wipes In The Waste Stream – And Win: Part 2 9/9/2015

    This is the second installment of a three-part series examining wipes in the waste stream. The first installment looked specifically at the growth of disposable wipes usage within the last decade. Now we’ll look at the public outreach campaigns and some of the ways pump manufacturers are adjusting their technology to try to reduce or prevent wipes-related clogging.

  9. Durango Wastewater Treatment Plant Foils Energy Heist And Lowers Maintenance Costs 8/8/2015

    The Durango wastewater treatment facility is a traditional waste-activated system. The bio-solids (WAS) is collected from secondary clarifiers, treated with flocculants and thickened before an anaerobic digestion. A centrifuge had been used for the thickening process which dewatered the WAS to a 8 to 10% consistency. The plant had three 50 hp units and used either one or two of the units as needed

  10. Wastewater Treatment Plant Protecting Wilderness With Membrane Bioreactor Technology 8/3/2015

    When it came time to design a new wastewater treatment plant for Field, the seasonal rise in population during the summer months added to the challenge of meeting Parks Canada's stringent mountain effluent targets. The goal of the new wastewater treatment plant was to protect this pristine wilderness area by setting the effluent target as close as possible to the natural composition of the receiving water bodies. With this in mind, Parks Canada reviewed the latest in advanced treatment technology and opted for a membrane bioreactor system
