Course programme

WASTEWATER TREATMENT

• Characteristics of wastewater.
• Pre-treatment of urban wastewater (screening, grit and oil removal, ...).
• Primary settling (technologies and design criteria).
• Biological treatments: conventional activated sludge process (hydrodynamic models and management issues).
• Treatments for nutrient removal (plant schemes and fields of application).
• Secondary settling (sedimentation theory and design criteria).
• Effluent disinfection (design and choosing).
• Start-up procedures for activated sludge processes.
• Wastewater treatment plant monitoring and data processing criteria.
• Treatment of sewage sludge (technologies and design criteria).
• Regulation and legislation.
• Laboratory tests: Sludge Volume Index (SVI), respirometric tests, foaming tests, ...
• Technical tour to a wastewater treatment plant.

DRINKING WATER TREATMENT

• Overview on drinking water.
• Drinking water treatments: conventional processes.
• Plant schemes for the treatment of groundwater and surface water.
• Design of drinking water treatment plant.
• Laboratory tests: jar tests, Freundlich adsorption isotherm, …

MUNICIPAL SOLID WASTE TREATMENT

• Regulatory aspects in solid waste classification and management.
• Conventional and separate collection of municipal solid waste.
• Municipal solid waste selection plant (technologies and plant scheme).
• Composting (technologies and plant schemes).
• Solid waste incineration (kilns, gaseous emission characteristics, gas cleaning technologies).
• Sanitary landfill (classification, design and management criteria).
• Design of a mass burning kiln for municipal solid waste incineration.
• Landfill design.
