EV4008 Advanced Oxidation Process Syllabus:
EV4008 Advanced Oxidation Process Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To identify the most critical issues and challenges that limit the use of conventional treatment processes in planning, design and operation of modern water and wastewater treatment facilities
To understand the fundamentals of advanced oxidation processes (AOPs), photochemistry, ozone chemistry, and its application to AOPs for the detoxification of contaminated water
To develop in-depth knowledge that can be used to devise and design effective AOP treatment systems to meet not only current but also anticipated regulatory requirements, and to enhance independent learning and critical thinking skills.
UNIT I INTRODUCTION TO AOPs
Introduction to AOPs for water and wastewater treatment – mechanism – photooxidation reactions photocatalytic reactions, photo initiated oxidation – UV- H2O2 / ozonation, fenton / photofenton – photocatalysis – light source choice – used in AOPs and their spectral distributions.
UNIT II HOMOGENOUS AOPs
Ozone, electro-chemical oxidation, ultrasonication, UV – photolysis, hydrogen peroxide and ultraviolet radiation (H2O2 /UV), Fenton and Photo Fenton’s oxidation, chemical and nonchemical AOPs, advantages and disadvantages of homogeneous processes.
UNIT III HETEROGENEOUS PROCESS
Introduction to nano & heterogeneous photocatalysis effect of system composition and process. Identification of degradation products, photoreactors (liquid phase/ gas phase) – solar/ artificial light photo reactors – operation of pilot plants – comparing reactor efficiencies – system design – solar collectors – technology issues – slurry, supported catalyst – reuse – novel photocatalysts, synthesis methods – bulk, chemical approaches, physical approaches, nanoporous materials – physic chemical methods for characterization of nanomaterials
UNIT IV AOP ENHANCEMENT TECHNIQUES
Non-thermal plasma-electron hydraulic cavitation and sonolysis- super water oxidation – γ rayselectron beams, Quantum yield improvement by additional oxidants – hydrogen peroxide persulphate– catalyst modification. case studies and applications semiconductor photolysis. process fundamentals, applications and commercial process.
UNIT V INDUSTRIAL APPLICATIONS AND ECONOMIC ASSESSMENT OF AOPs
Application of AOPs for textile, petroleum, pharmaceutical and petrochemical industries – ground water decontamination – drinking water treatment – pilot & land fill photochemical – cost calculation– economic analysis.
