91. Do More With Less: Integrating Nutrient Removal Control Improves Treatment Capacity And Efficiency 11/9/2017

    Wastewater treatment plants (WWTP) are facing many challenges. Permits on nitrogen and phosphorus in the effluent water are progressively becoming stricter in order to protect surface waters from eutrophication. At the same time, plants are required to reduce both energy and chemical consumption and are often challenged with limited time and staff. In total, they are required to do more with less. In order to meet these challenges, a plant with a Sequencing Batch Reactor (SBR) in Green Lake, Wisconsin was upgraded with an advanced process control system – the OSCAR process performance optimizer with NURO controller.

92. The Evolution Of High Speed Turbo In The Wastewater Industry 11/3/2017

    High speed turbo (HST) technology was the most quickly adopted blower design to enter the U.S. wastewater market.  HST appeared in 2006, at a time when there was a need for more efficient plant operation. 

93. 10 Water-Tech Winners From WEFTEC 2017 10/25/2017

    For the second straight year, the Water Environment Federation Exhibition and Conference (WEFTEC) came to McCormick Place in Chicago, returning also to the city which launched WEFTEC 90 years ago. As always, it was a showcase of the latest technologies and ideas available in the water/wastewater industry, but each show also has its own "feel" that reflects the times.

94. The Proper Application Of Rotary Lobe And Rotary Screw Blower Technology 9/28/2017

    Written by Kaeser’s system experts, this white paper compares rotary lobe and screw blowers, isochoric and isentropic compression, and how to properly apply these technologies for designing an energy efficient system.

95. How To Get A Biodigester At Your Plant 7/31/2017

    A wastewater treatment facility in Michigan has begun the complicated process of vetting a new, significant technology upgrade to its operations. What can you learn from its experience?

96. Packaged Wastewater Treatment For Uneven Terrain 7/31/2017

    Storey County, NV, just southeast of Reno, needed to replace an outdated wastewater treatment plant that serves the historic communities of Virginia City and Gold Hill. The new site was on the side of a hill, presenting challenges for the design of the plant and the orientation of its processes. Also, the new plant area was entirely within a district on the National Register of Historic Places. Read the full case study to learn how the new modular design allows for an efficient wastewater treatment solution.

97. Use Of Pure Oxygen To Resolve Capacity And Odor Problems 7/27/2017

    The Escalon Industrial Waste Water Treatment Facility’s service area is seasonal and centered on tomato and pickle processing. The production season (roughly mid-July through mid-October) sees high hydraulic- and BOD loads that strain the facility’s capacity. During the high season highly variable BOD load depletes DO and causes permit violations and odor complaints. Praxair installed 4 X 15 HP Medium Velocity Oxygenation (MVO™ oxygenation system), with the ability to deliver up to 6 TPD of oxygen to supplement the existing aeration capacity at the facility.

98. Value-Based Procurement: Steps In The Right Direction 5/10/2017

    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. 

99. Aeration System Eliminates Odors From Winery Wastewater Lagoons 5/1/2017

    A California winery was having odor problems from its wastewater evaporation lagoons. The wash and wastewater from this facility contain large amounts of organic matter. The wastewater is collected and pumped to two main lagoons for evaporation, percolation, and sprinkler irrigation.

100. Pulling Together: Public-Private Partnerships Poised To Push California Water Efficiency 4/11/2017

     California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.
