EV4203 Industrial Wastewater Pollution – Prevention and Control Syllabus:
EV4203 Industrial Wastewater Pollution – Prevention and Control Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To understand the principle of various processes applicable to industrial wastewater treatment
To impart knowledge on the concept and application of Industrial pollution prevention, cleaner technologies, industrial wastewater treatment and residue management.
To identify the best applicable technologies for wastewater treatment from the perspective of yield production.
UNIT I INTRODUCTION
Industrial scenario in India– industrial activity and environment – uses of water by industry – sources and types of industrial wastewater – nature and origin of pollutants – industrial wastewater and environmental impacts – regulatory requirements for treatment of industrial wastewater – industrial waste survey – industrial wastewater monitoring and sampling – generation rates, characterization and variables – toxicity of industrial effluents and bioassay tests – major issues on water quality management.
UNIT II INDUSTRIAL POLLUTION PREVENTION & WASTE MINIMISATION
Prevention vis a vis control of industrial pollution – benefits and barriers – waste management Hierarchy – source reduction techniques – periodic waste minimisation assessments – evaluation of pollution prevention options – cost benefit analysis – pay-back period – implementing & promoting pollution prevention programs in industries.
UNIT III INDUSTRIAL WASTEWATER TREATMENT
Flow and load equalisation – solids separation – removal of fats, oil & grease- neutralisation removal of inorganic constituents – precipitation, heavy METAL removal, nitrogen & phosphorous removal, Ion exchange, adsorption, membrane filtration, electro dialysis & evaporation – removal of organic constituents – biological treatment processes, chemical oxidation processes, advanced oxidation processes – treatability studies.
UNIT IV WASTEWATER REUSE AND RESIDUAL MANAGEMENT
Individual and common effluent treatment plants – Joint treatment of industrial and domestic wastewater – zero effluent discharge systems – quality requirements for wastewater reuse industrial reuse , present status and issues – disposal on water and land – residuals of industrial wastewater treatment – quantification and characteristics of sludge – thickening, digestion, conditioning, dewatering and disposal of sludge – management of RO rejects.
UNIT V CASE STUDIES
Industrial manufacturing process description, wastewater characteristics, source reduction options and waste treatment flow sheet for textiles – tanneries – pulp and paper – metal finishing – Oil refining–pharmaceuticals–sugar and distilleries
OUTCOME:
On Completion of the course, the student is expected to be able to
CO1 Explain the source and types of industrial wastewater and their environmental impacts and choose the regulatory laws pertaining to environmental protection
CO2 Identify industrial wastewater pollution and implement pollution prevention, waste minimization in industries
CO3 Apply knowledge and skills to design industrial wastewater treatment schemes
CO4 Audit and analyze environmental performance of industries to internal, external client, regulatory bodies and design water reuse management techniques
CO5 Conduct research to develop effective management systems for industrial wastewater that are technically sound, economically feasible and socially acceptable
