    9/17/2014

    Overcome the problem of fats, oils, and grease (FOG) by understanding it and choosing the right equipment.

  2. Can Nitrogen Removal And Enhanced Biological Phosphorus Removal Coexist?
    9/17/2014

    Enhanced biological phosphorus removal (EBPR) is considered the most economical and sustainable way to remove phosphorus from municipal wastewaters, but its integration with nitrogen removal puts EBPR at risk for failure.

  3. How To Select The Most Effective Blower Technology For Wastewater Applications
    9/16/2014

    Given numerous variables when selecting an aeration blower system for wastewater applications, and equally numerous claims by technology providers, it is not surprising that confusion exists. Worse than confusion is the disappointment that results when a blower technology fails to perform as anticipated — and operating cost and efficiency benefits go unrealized.

  4. Dairy Collective Reaps Green Energy And Environmental Benefits With Anaerobic Wastewater Technology
    9/16/2014

    One of the United States’ newest dairy processing plants features advanced wastewater treatment technology that not only radically improves biomass recovery and effluent quality, but also harnesses green energy from waste streams to drive production processes and reduce its carbon footprint.

  5. Why All The Hype About Chlorine Gas Safety?
    9/16/2014

    Remember when “Little Old Lady” Clara Peller rolled up to the drive-through window of Big Bun and asked “Where’s the beef?” She was asking a literal question, but also making a figurative statement. 

  6. What’s So “Smart” About Potable Smart Water Networks?
    9/15/2014

    Smart Networks— no matter if they are on the potable side of the industry or the wastewater side— seem to be one of the next battlegrounds for efficiency.

  7. Floating Islands For Stormwater And Other Applications
    9/15/2014

    Floating islands, also known as floating treatment wetlands (FTWs), are a relatively new technology for improving water quality and creating habitat.  Over 5,000 floating islands have been installed around the world in the past decade.

  8. New Developments In Thermal Dispersion Mass Flow Meters
    9/15/2014

    This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature. By John G. Olin, Ph.D., Founder/Chairman, Sierra Instruments

  9. Tackling The Drought: The Relationship Between Water Law And Water Budget
    9/15/2014

    Natural resource management usually involves more than science and engineering, it intersects law, policy, and politics.  Nowhere is this truer than in the regulation of water.

  10. A Tale Of Two Thermals: Capillary And Immersible
