The ability of mathematical models to mimic as well as predict the behavior of actual biological systems has negated the need for pilot-scale and full-scale trials to explore process solutions. As a result, the use of biological process modeling tools to design, upgrade and troubleshoot water resource recovery facilities (WRRFs) has become widely adopted in developed countries. A comprehensive characterization of the influent wastewater is a critical step for developing and fine tuning such models. Each and every plant treats a unique wastewater as each catchment differs in its composition and industrial dischargers. Further, the design of the wastewater collection system, geographic location, topography and climatic conditions can influence wastewater characteristics. As part of typical operation, WRRFs tend to perform some form of wastewater sampling and monitoring. However, sampling for wastewater characterization for modeling is normally much more detailed and intensive.

Our speakers in this Webcast will share specific and practical experiences that they have gathered in wastewater characterization. The discussion will be centered around but not limited to the following:

  • Important wastewater fractions and methods
  • Case studies of wastewater characterization (i.e., design, optimization for nutrient removal and troubleshooting)
  • Tradeoffs of data quantity, time and cost
  • Characterization of wastewater generated internally in treatment plants
