  1. A Fresh Approach To Odor Control

    The disposal of biosolids is an age-old conundrum for wastewater treatment facilities, faced with a pungent mix of economic and societal demands. In an effort to understand the alternatives, Spokane, WA recently commissioned HDR Engineering to complete a $125,000 study, according to Spokane Public Radio.

  2. Sizing Up New York’s Wastewater Treatment Facilities

    A new report published in the February 24th issue of the Water Research journal evaluates New York State’s publicly-owned treatment works (POTWs) and asks the question, “Is Bigger Better?”

  3. Turbo Blowers Evolving For Large Sewage Plant Efficiency

    Until recently, multi-stage centrifugal blowers and gear-driven single-stage turbo blowers have dominated larger wastewater treatment plant (WWTP) operations. Turbo blowers in the 50 hp to 300 hp range have historically been popular for their low total lifecycle cost in mid-range WWTP applications (from 1 MGD to 20 MGD).

  4. Big Air: Aerzen Introduces Turbo Blower For Large Treatment Plants

    Aerzen USA has long preached — and excelled in delivering — "right-sized" blower solutions, offering energy efficiency by producing the proper amount of air for the application. Until recently, however, the company did not have an option for the largest of wastewater treatment plants. That has changed with the introduction of the Multicore series turbo blower, which is described in the following video by Tom McCurdy, National Sales Manager for Aerzen's Environmental Group.

  5. The Hidden Costs Of Aeration

    To ensure that aeration equipment will provide not only the best overall solution for their treatment needs but also the lowest total cost of ownership, design engineers and plant operators must take into consideration three primary factors: blower selection, right-sizing, and smart control systems.


  6. Stepping Up To Smart Aeration

    According to the U.S. EPA, municipal water and wastewater treatment systems account for 30 to 40 percent of the total energy used by municipalities in the United States. In wastewater treatment, the biggest chunk of this energy consumption comes from aeration. Within a typical WWTP, the aeration equipment used to maintain the required dissolved oxygen (DO) levels in the activated sludge process can account for as much as 60 percent of the total plant energy use (Source: As municipalities and plant operators look for ways to minimize energy use and contain operating costs, aeration is a natural area of focus.

  7. Value-Based Procurement: Steps In The Right Direction

    As a means of encouraging the growth of new technologies and improving operating costs, water and wastewater equipment manufacturers have long advocated for changing the mindset of equipment procurement from low-bid to lowest life-cycle cost evaluation.This have proven to be a very daunting task. 

  8. Following Catastrophic Flood, Wastewater Workers Lead Recovery

    When electrical issues caused effluent pumps to shut down at the West Point wastewater treatment plant in Seattle, WA, influent levels began to rise and flooded the plant, leaving it severely damaged.

  9. With The Prospect Of Lighter Restrictions, Wastewater Upgrades Could Be In Vain

    With the Trump administration likely to loosen wastewater treatment regulations, utilities face a conundrum.

  10. Aerzen Combines Blower Technology And A New Control System For Energy Saving Operation Even In Case Of Load Changes

    If modernizations in wastewater treatment plants are due, as a rule the permanently reducing limit values of ammonium, nitrate and phosphate are pushing the investment decisions.
