CE6605 ENVIRONMENTAL ENGINEERING II L T P C 3 0 0 3
OBJECTIVES:
• To educate the students on the principles and design of Sewage Collection, Conveyance, treatment and disposal.
UNIT I PLANNING FOR SEWERAGE SYSTEMS 7
Sources of wastewater generation – Effects – Estimation of sanitary sewage flow – Estimation of storm runoff – Factors affecting Characteristics and composition of sewage and their significance – Effluent standards – Legislation requirements.
UNIT II SEWER DESIGN 8
Sewerage – Hydraulics of flow in sewers – Objectives – Design period - Design of sanitary and storm sewers – Small bore systems - Computer applications – Laying, joining & testing of sewers
– appurtenances – Pumps – selection of pumps and pipe Drainage -. Plumbing System for
Buildings – One pipe and two pipe system.
UNIT III PRIMARY TREATMENT OF SEWAGE 9
Objective – Selection of treatment processes – Principles, Functions, Design and Drawing of Units
- Onsite sanitation - Septic tank with dispersion - Grey water harvesting – Primary treatment –
Principles, functions design and drawing of screen, grit chambers and primary sedimentation tanks
– Construction, operation and Maintenance aspects.
UNIT IV SECONDARY TREATMENT OF SEWAGE 12
Objective – Selection of Treatment Methods – Principles, Functions, Design and Drawing of Units - Activated Sludge Process and Trickling filter – Oxidation ditches, UASB – Waste Stabilization Ponds – Reclamation and Reuse of sewage - sewage recycle in residential complex - Recent Advances in Sewage Treatment – Construction and Operation & Maintenance of Sewage Treatment Plants.
UNIT V DISPOSAL OF SEWAGE AND SLUDGE MANAGEMENT 9
Standards for Disposal - Methods – dilution – Self purification of surface water bodies – Oxygen sag curve – Land disposal – Sludge characterization – Thickening – Sludge digestion – Biogas recovery – Sludge Conditioning and Dewatering – disposal – Advances in Sludge Treatment and disposal.
TOTAL: 45 PERIODS
OUTCOMES:
The students completing the course will have
• ability to estimate sewage generation and design sewer system including sewage pumping stations
• required understanding on the characteristics and composition of sewage, self purification of streams
• ability to perform basic design of the unit operations and processes that are used in sewage treatment
