EV4201 Biological Treatment Process for Wastewater Syllabus:
EV4201 Biological Treatment Process for Wastewater Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To educate the students on the principles and process designs of various treatment systems for wastewater
To gain competency in the process employed in design of treatment systems and the components comprising such systems, leading to the selection of specific process.
UNIT I REACTION KINETICS AND BIO REACTORS
Objectives of biological treatment – significance – principles of aerobic and anaerobic treatment – kinetics of biological growth – factors affecting growth – attached and suspended growth – determination of kinetic coefficients for organics removal – enzyme kinetics biodegradability assessment – selection of process- reactors- biokinetics – batch reactor – continuous flow stirred tank reactor-plug flow reactor – flow charts, layout, PID, hydraulic profile
UNIT II CONVENTIONAL AEROBIC TREATMENT PROCESSES
Design of sewage treatment plant units –activated sludge process and variations – trickling filters- biotower- RBC- fluidized bed reactors, aerated lagoons, waste stabilization ponds – natural treatment systems, constructed wetland – nutrient removal systems- disposal options – reclamation and reuse – recent trends.
UNIT III ADVANCED AEROBIC TREATMENT PROCESSES OF WASTEWATER
Sequencing batch reactors- moving bed biofilm reactors- membrane bioreactor- reclamation and reuse of wastewater-design of tertiary treatment units-application of membrane separation technologies in reuse of sewage -nutrient removal systems-case studies
UNIT IV ANAEROBIC TREATMENT OF WASTEWATER
Attached and suspended growth process – design of units – UASB – post treatment systems for UASB reactor-anaerobic filters – expanded bed and fluidized bed anaerobic systems – septic tank and soil disposal system – anaerobic baffled reactor – design of nutrient removal systems – anaerobic ammonium oxidation process – recent trends.
UNIT V SLUDGE TREATMENT, OPERATION AND MAINTENANCE
Sources and its characteristics-design of sludge management facilities, sludge thickening- sludge digestion – biogas generation- sludge dewatering- mechanical – ultimate residue disposal – recent advances-construction and operational maintenance problems in STPs– trouble shooting – planning, organizing and controlling of plant operations – capacity building – retrofitting case studies
