Technical Program


Workshop A Process Design of Industrial and Municipal Wastewater Treatment Systems
Sunday, July 26 | 8:00am - 5:00pm

A highly qualified team of speakers which will present the basic principles of treatment process design and modeling as well as the models used today. The speakers will review the basic principles of organics, nutrients and microconstituent removal used today in the modeling tools. The various wastewater technologies used today will be summarized relative to capital and O&M costs and advantages and disadvantages. A case study from the pharmaceutical industry will show the results of process development, pilot testing and scale-up. Attendees will gain experience in solving real process design problems for both organics and nitrogen removal in nitrification and denitrification processes. These problem solving sessions will provide the attendees with a better understanding of the basic principles and confidence in the use of the state-of-the-art modeling tools and how to interpret and understand the model outputs. Dynamic modeling of wastewater treatment plants (WWTPs) offers a number of valuable insights into plant operations, including trouble-shooting, optimizing plant process operations, and training plant staff. The application of the currently published activated sludge models (e.g. ASM1) to the modeling of plants treating domestic wastewater has been well documented. Conversely, the application of these models to the simulation of facilities treating industrial wastewaters has been less common. The simulation of industrial activated sludge plants poses special challenges due to the unique and highly variable nature of the wastewater and the extreme operating conditions often encountered. This segment of the workshop will discuss the special challenges associated with modeling industrial WWTPs, highlight the model enhancements often required to handle industrial situations, provide examples of pharmaceutical, pilot-testing, scale-up, design, lessons learned, modeling and outline future industrial modeling trends including: tracking the dynamic fate of specific trace organic compounds (including metabolite formation and removal), modeling the effect of inhibitory levels of substances on biological competence, contaminant fate and biomass settling characteristics, and on-line modeling with potential to include warnings of imminent upsets and knowledge-based solutions.
