  1. Wastewater Plant Streamlines Process Monitoring 7/13/2018

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

  2. Optimizing Chemical Dosing Reduces Chemical Use While Meeting Effluent TP Limits 11/9/2017

    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 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.

  4. ICEAS SBR Technology Improves Effluent Water Quality For St. Joseph WWTP 3/15/2015

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

  5. ICEAS SBR Technology Enters 30th Year Of High-Quality Effluent Production 3/25/2015

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

  6. State-Of-The-Art Treatment Equipment Greatly Reduces Plant's Energy Consumption 3/25/2015

    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.

  7. Wastewater Treatment System Achieves Stringent Water Quality Discharge Limits And Reduces Costs 3/9/2015

    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.

  8. Meeting State Nutrient Regulations With SBRs 1/15/2014

    After the Missouri Department of Natural Resources reclassified the effluent receiving stream in the city of Sullivan, officials learned that its wastewater treatment lagoon required a more advanced treatment process to comply. They selected a continuous-flow sequencing batch reactor (SBR) system that utilizes a modified activated sludge biological treatment. The new infrastructure has provided cost-saving results for the ongoing removal of nitrogen and phosphorous.

  9. Upgrade To Diffused Aeration Results In Significant Energy Savings 12/12/2013

    After 35 years of use,  the fiberglass jet aeration manifolds in the Western Regional Water Reclamation Plant (Dayton, Ohio) had deteriorated, rendering four of eight wastewater aeration tanks inoperable. Managers recognized an opportunity to utilize a fine bubble diffused aeration system that eliminated the need for the pumps. The result: higher oxygen-transfer efficiency and reduced power costs to operate the system.

  10. Continuous Fill SBR Tanks Help WWTP Exceed Effluent Requirements, Generate Additional Revenue 12/10/2013

    In order to meet the anticipated effluent criteria required by the Pennsylvania DEP, the Newville Borough Water & Sewer Authority determined that its existing wastewater treatment facility needed renovations. By installing two continuous fill SBR tanks, the facility lowered total nitrogen below permit limits, reduced energy costs, and created a new revenue stream (selling unused nutrient allocations).
