Group A

Introduction: Review of environmental engineering.
Biological processes for water and wastewater quality enhancement. Microbiological aspects,
classification of bioprocesses, aerobic and anaerobic processes, dispersed and immobilized
growth systems, reactor analysis, unit operations and processes, aerobic dispersed growth
systems—activated sludge process and its modifications, aerobic immobilized growth
systems-trickling filters, rotating biological contactors, anaerobic processes-conventional,
stationary and mobile, fixed film, sludge blanket, ponds and lagoons, septic tanks.
Overview and elements of wastewater disposal scheme: Primary, secondary and tertiary
treatment, sequencing of unit operations and processes, plant layout, hydraulic
Disposal of wastes: Liquid—inland waters, on land, ocean; disposal standards—effluent and
stream, gaseous-atmospheric dispersion, meteorological and stack factors, emission

Group B


Air pollution control; Stack height estimation, particulate removal mechanisms and
processes, reduction of gaseous pollutants—adsorption, absorption, neutralization,
Solid waste management: Collection, classification, reduction—quantity and hazard
potential, composting. land filling, incineration, ground water pollution.
Noise pollution and hazardous waste management: Definition, measurement, control
Environmental impact and auditing: Environmental impact and assessment—statements and
methodologies, environmental laws—special constitutional provisions, role of federal and
state governments and NGOs in monitoring and control of environmental pollution and
resources, environmental auditing.
