Energy consumption model for wastewater treatment process control
Wastewater treatment must satisfy discharge requirements under specified constraints and have minimal operating costs (OC). The operating results of wastewater treatment processes (WWTPs) have significantly focused on both the energy consumption (EC) and effluent quality (EQ). To reflect the relationship between the EC and EQ of WWTPs directly, an extended Elman neural network-based energy ...

Minnesota debates phosphorus discharge limits for improved water quality
City leaders across the Minnesota River Basin are protesting proposed phosphorus standards, which they contend will be too expensive and have little or no effect on water quality. In January, 41 of the 147 Minnesota cities in the basin outlined their objections in a letter to the governor and the Minnesota Pollution Control Agency. Many of these cities’ wastewater treatment plants ...

The Coastal Brewing Company - Case Study
Situation Making beer is a water intensive process that generates wastewater high in nutrients, biological oxygen demand (BOD) and total suspended solids (TSS). Given the nature of this high strength wastewater, many breweries face discharge fees, with some even trucking wastewater offsite. The Coastal Brewing Company, a new brewery based in Forster, Australia, had to reduce BOD in its ...

Innovative Ammonia Control - Case study
Ammonia has increasingly become more of a regulatory concern. Ammonia emissions into the atmosphere have been linked to the formation of fine particulate matter, while ammonia emissions in wastewater are restricted because of the negative affect the chemical has on rivers, lake, and aquifers. Many sources of biofuels contain ammonia or can create ammonia during processing. The following case ...
