  1. Wastewater Plant Streamlines Process Monitoring

    In its quest to gain greater remote accessibility and increase ease of use, a progressive sewerage authority elects to think outside the traditional SCADA box.

  2. Optimizing Chemical Dosing Reduces Chemical Use While Meeting Effluent TP Limits

    The city of Black River Falls in Wisconsin used chemical treatment with ferric chloride (FeCl3) to achieve their effluent total phosphorus (TP) permit of 1.0 mg/l. Historically, the chemical dosing rate was manually adjusted on a daily basis based on the measured effluent TP concentration. The plant was upgraded with an OSCAR process performance optimizer control system with phosphorus controller, which uses continuous measurement of orthophosphate.

  3. Do More With Less: Integrating Nutrient Removal Control Improves Treatment Capacity And Efficiency

    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.

  4. NURO Controller For ICEAS Advanced SBR Processes

    These days, operators are required to do more with less due to stricter nitrogen and phosphorus permits, pressure to reduce energy and chemical usage, and limited time and staff. How could these challenges be met without a plant reconfiguration?

  5. Energy Efficiency And Emissions Reduction In Wastewater Management

    Nearly 50% of electricity-related emissions from the global wastewater sector could be abated at negative cost by investing in readily available technologies.

  6. ICEAS SBR Technology Improves Effluent Water Quality For St. Joseph WWTP

    St. Joseph Sanitary District No. 1, near La Crosse, WI, operated a wastewater treatment plant (WWTP) that served approximately 1,000 residential customers.

  7. ICEAS SBR Technology Enters 30th Year Of High-Quality Effluent Production

    In the late 1970s, a wastewater treatment plant (WWTP) in Tullahoma, TN, built in 1955, was overloaded and deteriorating.

  8. State-Of-The-Art Treatment Equipment Greatly Reduces Plant’s Energy Consumption

    Driven by compliance with more stringent water treatment standards, the Fond du Lac Wastewater Treatment Plant (WWTP) leveraged the upgrade opportunity to improve beyond limiting ammonia effluent levels. The plant improved energy fficiency, reduced maintenance and operating costs, and eliminated bypasses into Lake Winnebago during high rainfall.

  9. Xylem Launches New Eco-Lift Retrievable Aeration Grid Delivering Superior Aeration Efficiency

    Xylem Inc., a leading global water technology company focused on addressing the world’s most challenging water issues, has launched a new retrievable aeration grid system that delivers superior aeration efficiency in wastewater treatment plants.

  10. Wastewater Treatment System Achieves Stringent Water Quality Discharge Limits And Reduces Costs

    The Village of Johnson Wastewater Treatment Facility (WWTF) was among the first in the state of Vermont to meet newly enacted secondary treatment requirements when it began operation in 1970.
