EV4003 Environmental System Analysis Syllabus:
EV4003 Environmental System Analysis Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To introduce the modelling concept in various environmental field like ecological modelling, CSTR modelling and the kinetics of reaction
To gain knowledge on river and stream water modelling and soft computing techniques.
UNIT I ECOLOGICAL SYSTEM
Basic concepts in ecology and ecological modelling, population dynamics: birth and death processes. Single species growth, prey-predator models: Lotka-Volterra, Rosenzweig-MacArther, Kolmogorov models. multi-species modeling – structural analysis and stability of complex ecosystems.
UNIT II REACTOR MODELLING
CSTR, plug-flow, dispersion. A case study of a tubular reactor with axial dispersion, parameter calibration: search algorithms for nonlinear dynamical models, variance of estimated parameters. application to Monod and Haldane kinetics.
UNIT III WATER QUALITY MODELLING
Rivers and streams water quality modeling -dispersion and mixing- water quality modelling processmodel sensitivity-assessing model performance; models for dissolved oxygen and pathogenspollutant and nutrient dynamics -dissolved oxygen dynamics -groundwater quality modeling.
UNIT IV MICROBIAL DYNAMICS AND ENERGETICS
Requirements for carbon and nutrient removal. Activated sludge: process schemes: completely mixed, plug-flow, SBR, nutrient removal. Anaerobic digestion: process dynamics, operational control of wastewater treatment processes.
UNIT V COMPUTER BASED SOLUTIONS
Formulation of linear optimization models. linear programming. sensitivity testing and duality. Solution techniques and computer programming; Formulation of linear optimization models. Application of models- simulation, parameter estimation and experimental design.
