Course Content

  • LOCAL & REGIONAL REGULATIONS

      • Operating permit: structure, contents, key chapters, elaboration and updating process.
      • Waste water specifications. Penalties in case of violation (formal requirements, fines).

  • WASTE WATER CHARACTERISTICS

      • Natural sources and components. Various uses of water in operating units. Effluent rejection points.
      • Nature of water pollutants (hydrocarbons, acidity, suspended matters, phenols, sulfides, mercaptans).
      • Analytical methods used in the laboratory and through on-line analyzers. BOD, COD, TOC.
      • Pollution mechanisms, impact on environment (insoluble, organic carbon, eutrophization, sludge).
      • Measurement of pollution: pollutant concentrations, quantities by unit of time. Typicals.

  • PHYSICO-CHEMICAL WATER TREATMENT PROCESSES

      • Process water stripping: typical process scheme, optimum operating conditions.
      • Settling of insoluble hydrocarbons and sludge. Settling velocity. Settler design types and improvements.
      • Dissolved air floatation: equipment, flocculation additives, additive mix and operating parameter optimization.
      • Filtration: various equipment, sand, active carbon beds, other filtration media.

  • BIOLOGICAL TREATMENT OF WASTE WATER

      • Growth of bacteria colonies. Required feed and nutrients. Biofiltration of process water.
      • Biological treatment technology: bacteria filters, activated sludge basins. Operating conditions.

  • BIOLOGICAL SLUDGE TREATMENT

      • Sludge physio-chemical properties
      • Thickening methods: settling, press filtration, flocculation-floatation, centrifugation.
      • Analytical test methods: dry matter, heat value, volatile fractions, heavy metals.
      • Treatment processes: digester, wet oxidation, thermal hydrolysis, incineration, smell control.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • identify the impact of pollution on the environment,
  • adapt treatment operating parameters to the properties of incoming polluted water issued from refinery or petrochemical plant,
  • improve the operation and maintenance of equipment,
  • react effectively in adverse situations,
  • set a basis for regulation.

Ways & Means

  • Equipment demos (material, pictures and videos).
