EV4103 Physical and Chemical Treatment Systems for Water and Wastewater Syllabus:
EV4103 Physical and Chemical Treatment Systems for Water and Wastewater Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVE:
To understand about the various pollutants present in water and wastewater and to choose the respective physico-chemical systems for effective treatment
To apply the knowledge for municipal, industrial water and wastewater treatment plants and design suitable treatment schemes
To gain advance knowledge on the emerging environmental issues on treatment systems and conduct research to identify most appropriate treatment schemes
UNIT I INTRODUCTION
Pollutants in water and wastewater–characteristics, standards for performance- significance of physico-chemical treatment–Selection criteria-types of reactor-reactor selection-batch-continuous type-kinetics
UNIT II TREATMENT PRINCIPLES
Physical treatment – screening – mixing, equalization –sedimentation – filtration – evaporation– incineration–gas transfer–mass transfer coefficient adsorption – isotherms – membrane separation, Reverse Osmosis, nanofiltration, ultrafiltration and electrodialysis, distillation– stripping and crystallization – recent advances.
Principles of Chemical treatment– Coagulation – flocculation–Precipitation – flotation – solidification and stabilization–Disinfection, Ion exchange, Electrolytic methods, Solvent extraction–advanced oxidation/reduction– recent trends
UNIT III DESIGN OF MUNICIPAL WATER TREATMENT PLANTS
Selection of treatment–design of municipal water treatment plant units–aerators–chemical feeding– flocculation–clarifier–tube settling–filters–rapid sand filters, slow sand filter, pressure filter, dual media filter – disinfection flow charts– layouts –hydraulic profile ,PID-construction and O&M aspects– case studies, residue management – upgradation of existing plants – recent trends.
UNIT IV DESIGN OF INDUSTRIAL WATER TREATMENT PLANTS
Design of industrial water treatment units-selection of process–design of softeners –demineralisers– Reverse osmosis plants–flow charts–layouts–hydraulic profile, PID-construction and O&M aspects– case studies, residue management–upgradation of existing plants –recent trends.
UNIT V DESIGN OF WASTEWATER TREATMENT PLANTS
Design of municipal wastewater treatment units-screens- grit chamber-settling tanks- sludge thickening – sludge dewatering systems – sludge drying beds – design of industrial wastewater treatment units – equalization – neutralization – chemical feeding devices – mixers – floatation units – oil skimmer – flowcharts – layouts – hydraulic profile, PID, construction and O&M aspects – case studies, retrofitting – residue management – upgradation of existing plants – recent trends.
OUTCOME:
On Completion of the course, the student is expected to be able to
CO1 Explain the significance of various pollutants present in water, wastewater and develop the kinetics for reactor design
CO2 Choose the relevant physico-chemical systems for effective water and wastewater treatment
CO3 Design the treatment scheme for municipal and industrial water, wastewater to meet the specific needs on residue management and up gradation of existing plants
CO4 Identify environmental issues in the society on wastewater treatment and formulate technical solutions that are economically feasible and socially acceptable
CO5 Conduct research to identify and design most appropriate treatment schemes for the emerging environmental issues on treatment systems in collaboration with municipalities, corporation, pollution control boards and industries
