EV4015 Operation and Maintenance of Water and Wastewater Treatment Systems Syllabus:
EV4015 Operation and Maintenance of Water and Wastewater Treatment Systems Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVE:
To educate the student on the various operation & maintenance aspects of water treatment systems, sewer systems, sewage treatment plants and effluent treatment plants.
UNIT I ELEMENTS OF OPERATION AND MAINTENANCE
Strategy for good operation and maintenance- preventive and corrective maintenance scheduling – operation and maintenance Plan – proper and adequate tools, spare units and parts – training requirements- laboratory control- records and reports- housekeeping –sampling procedure analytical techniques- code of practice for analytical laboratories- measurement of flows, pressures and Levels -safety in O&M operations – management information system – measures for conservation of energy
UNIT II OPERATION AND MAINTENANCE OF WATER SUPPLY SYSTEMS
Operational problems, O&M practices and records of operation of reservoir and intakes – causes of failure of wells- rehabilitation of tube wells & bore wells- prevention of incrustation and corrosion – problems in transmission mains- maintenance of pipelines and leakage control- repair method for different types of pipes- preventive and corrective maintenance of water pumps – problems in the water distribution system and remedies- water quality monitoring and surveillance
UNIT III OPERATION AND MAINTENANCE OF SEWERAGE SYSTEMS
Components and functions of sewerage system – maintenance of collection system – operational problems– clogging of pipes – hazards – precautions against gas hazards – precautions against infections – devices for cleaning the conduits – preventive and corrective maintenance of sewage pumps –operation and maintenance of sewage pumping stations- maintenance hazards and operator protection –SOP-case studies
UNIT IV OPERATION AND MAINTENANCE OF PHYSICO-CHEMICAL TREATMENT UNITS
Operation and maintenance in screen chamber, grit chamber and clarifiers- operation issues, trouble shooting guidelines and record keeping requirements for clarifier, equalization basins, neutralization unit – chemical storage and mixing equipment – chemical metering equipment – flash mixer –filters, thickeners and centrifuges- filter press – start-up and maintenance inspection – motors and pumps – hazards in chemical handling – jar test – chlorination equipment – membrane process systems- SDI and LSI determination- process chemistry and chemical dosage calculations- SOP-case studies
