Consulting vs Support

The difference between support and consulting are illustrated below:

  1. Questions related to the software such as ‘How do I export my data?’, ‘What model best simulates a trickling filter?’, or ‘How do I customize my Album?’ would be considered support questions.
  2. Questions related to process engineering such as ‘How do I achieve an effluent nitrate concentration of less than 5 mg/l?’ would be better answered by our consulting services team.
Building a BioWin Model

Building a BioWin Model

Building a calibrated BioWin model involves configuration of the model and calibration against historical plant data. Typical data required are:

  • Physical plant dimensions
  • Plant operating data such as recycle rates and DO concentrations
  • Influent flow and loading data
  • Influent wastewater characteristics

A good overview of a structured modeling approach is provided in “Region-wide Wastewater Treatment Plant Modeling Enhances Facility Management and Planning’, Bye et al“. A comprehensive explanation can be found in the WERF manual ‘Methods for Wastewater Characterization in Activated Sludge Modeling’.
