Wastewater Treatment System Planning
Winter semester
Description and rationale: Mathematical models and their applications to design and operation of processes
used in wastewater treatment; emphasis is on biological treatment processes and related processes for sludge
treatment. Issues on wastewater reclamation and reuse are also discussed in terms of process selection and risk
analysis.
Keywords: Process analysis and design, characteristics of water, treatment processes and process dynamics,
risk analysis consideration in design
Pre-requisite:
none
Expected students: master’s and doctoral
Instructor:
Prof Naoyuki FUNAMIZU
Course outline:
(1) Introduction
Course outline and emphasis.
(2) Introduction to process analysis and design
Design parameters and operation parameters for wastewater treatment system; selection and evaluation of
model structure.
(3) Characteristics of wastewater
Characterization of wastewater constituents; variation in wastewater flow rate, concentrations and mass
loading rates.
(4) Biological treatment and nutrient removal
Introduction to microbial metabolism, energetics, and growth; modeling of biological treatment kinetics;
biological nutrient removal; suspended-growth processes.
(5) Sedimentation and thickening of sludge
Hindered sedimentation; dynamic model for thickening and clarification
(6) Anaerobic digestion
Identifying significant anaerobic reactions in a reactor; stoichiometry and kinetic parameters; material
balances in gas, liquid and biological phases.
(7) Wastewater reclamation and reuse
Treatment operations and processes for reclamation and repurification; removal of residual solids;
wastewater disinfection
(8) Risk analysis consideration in design
Four steps in human health risk assessment; hazard identification; dose-response analysis; exposure
assessment; risk characterization
Grading:
