EN3006 Design of Water and Wastewater Treatment Plants Syllabus:
EN3006 Design of Water and Wastewater Treatment Plants Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
To educate the students on the principles and process designs of various treatment systems for water and wastewater.
Develop an understanding of the characteristics of water and wastewater that must be considered during design of a treatment plant.
Students will gain competency in the iterative process employed in design of treatment systems and the components comprising such systems, leading to the selection of specific process equipment items.
UNIT I PRINCIPLES OF TREATMENT
Pollutants in water and wastewater – characteristics – treatment processes – Selection criteria-types of reactors – kinetics – Unit operations and unit processes- – screening, skimming, floatation – mixing, equalization, sedimentation, filtration – gas transfer – adsorption – Isotherms –membrane separation, neutralization – coagulation flocculation – precipitation – stabilization – disinfection, Ion exchange – advanced oxidation processes.
UNIT II DESIGN OF WATER TREATMENT PLANTS
Design of treatment plant units – selection of process – upgrading existing plants – aerators – chemical feeding – Flash mixer- Clariflocculator – lamella and plate settlers- – filters – rapid sand filters, pressure filter, dual media filters-Multimedia filters – disinfectors- design of softeners – demineralization plant –reverse osmosis plants.
UNIT III DESIGN OF CONVENTIONAL WASTEWATER TREATMENT PLANTS
Design of aerobic treatment systems – activated sludge process and variations, trickling filtersbio tower-RBC- aerated lagoons – natural treatment systems- waste stabilization ponds, constructed wetland – Disinfection – Nutrient removal systems
UNIT IV DESIGN OF ADVANCED WASTEWATER TREATMENT PLANTS
Design of sequencing batch reactors- moving bed biofilm reactors- membrane bioreactorreclamation and reuse of wastewater – application of membrane separation technologies in reuse of sewage -nutrient removal systems- UASB – post treatment systems for UASB reactoranaerobic filters -recent trends.
UNIT V RESIDUAL MANAGEMENT OPERATION AND MAINTENANCE ASPECTS
Characteristics of sludge from WTP and STP-Design of sludge management facilities for WTP and STP-sludge thickening-sludge digestion- design of anaerobic digester-biogas generation- sludge dewatering –filter press – centrifugation– sludge drying beds – construction, operation and Maintenance aspects of WTP and STP – trouble shooting – capacity building, case studies of Retrofitting.
TOTAL 45 PERIODS
