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

How Digitalization Can Boost Natural Disaster Resiliency In Municipal Water And Sewerage Treatment
Digitalization of the municipal water treatment industry is fragmented today, with instrumentation, control, and automation technologies mixed with manual operational activities. Such infrastructures can be detrimental in cases of hydro-geological events, such as severe storms and earthquakes. The good news: When natural disasters strike, digitalization can help get municipal water treatment back online quickly and effectively.

White Paper: Performance Of Floating Horizontal Aerators In Aerated Lagoons And Oxidation Ditches When selecting aeration equipment to use for a specific application, issues to address include reliability, serviceability, capital cost, system appurtenances, and cost of operation and maintenance. Another important consideration is oxygen transfer rate (OTR). Horizontal floating aerators have relatively high transfer rates and have been used successfully in aerated lagoons and oxidation ditches. Using equipment with high OTR values reduces the horsepower input that is required and subsequently lowers capital cost and O&M costs. Mixing of wastewater in lagoons and oxidation ditches is also important to maintain solids in suspension
