• The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.

  • Learn how a wastewater treatment plant replaced their existing aeration system, realizing better treatment and 50% savings in operating costs. 

  • Explore how a wastewater treatment plant realized significant energy savings and increased performance with adaptive mixer technology. 

  • The City of Shelby, Ohio recently upgraded its activated-sludge wastewater treatment plant to double its capacity to 5 MGD, while expanding its capability to treat and disinfect combined high-volume stormwater and wastewater flows generated by wet-weather conditions.

  • In this case study, discover how a WWTP used a Mazzei aeration system to continue meeting its permit requirements without adding to the daily responsibilities of plant personnel. 

  • Read how Mazzei provided aeration equipment to a water purification facility in Yankton, South Dakota, that was conveniently installed out of sight in the building's basement. 

  • In the daily rush to ensure that all the mechanical, electrical, and operational procedures are followed — monitoring inflow volumes and organic/nutrient loads; servicing and maintaining motors, pumps, and other electrical and mechanical equipment; maintaining chemical treatments to ensure effluent compliance — it is too easily forgotten that wastewater treatment is primarily a biological process.

  • Aire-02 was approached by a large sugar beet processing facility that was in desperate need of a rapid and effective solution for their deteriorating wastewater treatment system.

  • Process control is key to maximizing wastewater treatment efficiency while minimizing operating costs. Implementing the right process control system in conjunction with the right equipment can save money on electrical costs and equipment maintenance.

  • Bose Cascade’s Ft. Frances, Ontario kraft mill operation faced a wastewater treatment problem due to dead spots in nearly half of its aerated stabilization basin. Newterra's Aire-O2 came to the rescue.


  • Sanitaire ICEAS® Advanced SBR Technology by Xylem

    Sanitaire has provided the wastewater treatment industry with innovative and cost-effective treatment technologies for over 35 years. This tradition continues with the Sanitaire Intermittent Cycle Extended Aeration (ICEAS) process, which is an advance sequencing batch reactor (SBR) technology for municipal and industrial wastewater treatment.

  • RollsAIR Extended Aeration Systems

    RollsAIR™ & RollsAIR™ HS-STP®: Offering versatility and consistent high performance for multi-family residential and large commercial properties. The RollsAIR™ and the RollsAIR™ HS-STP® offer a cost effective method to treat larger flows for a multitude of applications.

  • Sigma Air Manager Series

    System controls are critical to a wastewater blower system. Without them, a system with multiple blowers operating on their individual controls will run more than necessary and result in wasted energy. Maintenance costs increase and worst of all: process performance suffers.

  • Submersible Aerator Type ABS XTA/XTAK

    The XTA and XTAK are self-aspirating submersible aerators for wastewater and water treatment in municipal and industrial plants. The main areas of application are mixing and equalization tanks, activated sludge tanks, SBR, and sludge storage tanks.

  • Rotary Screw Blower Packages

    Kaeser screw blowers use up to 35 percent less energy than conventional rotary blowers and even achieve significant energy savings compared to currently available screw blowers. The combination of a blower airend with high efficiency Sigma profile rotors, flow-optimized components, efficient power transmission and drive components ensures exceptional performance, guaranteed by Kaeser in accordance with the stringent requirements of ISO 1217.
