EN3503 Wastewater Engineering Syllabus – Anna University Regulation 2021
COURSE OBJECTIVE:
The objectives of this course is to help students develop the ability to apply basic understanding of physical, chemical, and biological phenomena for successful design, operation and maintenance of sewage treatment plants.
UNIT I PLANNING AND DESIGN OF SEWERAGE SYSTEM
Characteristics and composition of sewage– population equivalent -Sanitary sewage flow estimation – Sewer materials – Hydraulics of flow in sanitary sewers – Sewer design – Storm runoff estimation – sewer appurtenances – sewage pumping-drainage in buildings-plumbing systems for drainage- Discharge standards for Effluents.
UNIT II PRIMARY TREATMENT OF SEWAGE
Objectives – Unit Operations and Processes – Selection of treatment processes –- Onsite sanitation – Septic tank- Primary treatment – Principles, functions and design of sewage treatment units – screens – grit chamber-primary sedimentation tanks –Operation and Maintenance aspects.
UNIT III SECONDARY TREATMENT OF SEWAGE
Objectives – Selection of Treatment Methods – Principles, Functions, – Activated Sludge Process and Extended aeration systems –Rotating biological contactors-Trickling filters Waste Stabilization Ponds – Operation and Maintenance
UNIT IV ADVANCES IN SEWAGE TREATMENT
Sequencing Batch Reactor – Moving bed biofilm reactor-Membrane Bioreactor – UASB – Biogas recovery- Reclamation and Reuse of sewage – Constructed Wetland –Nutient removal systems.
UNIT V SEWAGE DISPOSAL AND SLUDGE MANAGEMENT
Dilution – Self purification of surface water bodies Oxygen sag curve – deoxygenation and reaeration – Land disposal – Sewage farming – sodium hazards – Soil dispersion system. Objectives – Sludge characterization – Sludge Thickening – Dewatering – Drying – ultimate residue disposal – Septage Management.
TOTAL: 45 PERIODS
