    • Dynamic model performance and analysis
    • Time-series charts and dynamic results output
  • Modeling Diffused Aeration Systems
    • Air flow requirements
    • Impact of diffuser density, tank depth and operating conditions
    • SOTE plots
  • Secondary Clarifiers
    • Settler modeling
    • Sludge settleability measures
    • State point analysis and solids profiles

    • Impact of return streams

A one-day course exploring energy + operating expenses.

  • BioWin 5.0 enables users to capture a plant-wide inventory of power demand. For example, BioWin will calculate blower power requirements, taking into account factors such as inlet air temperature and relative humidity, pressure losses in the air delivery system, etc. Pumping power may also be tracked, accounting for detailed factors such as pipe material and diameter for dynamic head losses. Miscellaneous mechanical power for various treatment flowsheet elements also may be tracked.
  • To complement this new functionality, BioWin also includes the facility to easily implement up to three different electricity tariff rates over the day, and these patterns can be different across two “seasons” (e.g. summer and winter). With the additional ability to explore onsite power generation and heat recovery via CHP, tracking of other costs including consumables (e.g. methanol and metal salts) and sludge disposal, BioWin 5.0 has expanded capability as a plant management tool.

The advanced BioWin course is designed to cover a range of topics on application of BioWin. The assumption is that the majority of attendees are “experienced” BioWin users. The primary objectives are to provide information on certain model details, and to cover a range of example applications of BioWin.

The case studies and discussions may cover some of the following topics:

  • New BioWin Features
  • pH Modeling
  • pH model approach in BioWin
  • Modeling when pH is critical
  • Process Control Simulation
  • Simulation of on/off, high/low, ratio, P, PI, PID control
  • Aeration control simulation
  • Methanol Addition
  • Methanol-utilizing biomass modeling
  • Calculation of methanol requirements
  • Aeration Systems
  • Fine versus coarse bubble performance
  • Gas phase modeling and off-gas concentration analysis
  • Membrane Bioreactors
  • Nutrient removal MBRs
  • Impact of chemical dosing and return liquors
  • Biofilm Modeling
  • Biofilm model approach in BioWin
  • Modeling an IFAS system
  • Anaerobic Digestion
