International Conference on Sanitary Engineering, Water Quality and Solid Waste Management ICSEWQSWM on October 16-17, 2025 in Kathmandu, Nepal

Water Quality Management

Anthropogenic influences on living organisms in subterranean communities and the possibilities of influencing them
Water quality management and measurement of water quality in the eco-systems of ground and surface waters
Toxicological research on fish from surface waters with anthropogenic loads
Management of storm water from settlements

Water Supply

Physical water treatment
Subterranean water treatment
Subterranean removal of iron, manganese, arsenic, nitrates
Prevention of bacterial contamination of filters and ion exchangers
Biological elimination of nitrates and chlorinated hydrocarbons by micro-organisms; prevention of contamination with pesticides
Groundwater sanitation
Conserving water supplies and using storm water

Wastewater

Treatment and transport of storm water flow
Concepts for drainage systems
Development of processes for nitrification, denitrification, biological and chemical removal of phosphorus as well as for anaerobic treatment of industrial sewage
Management of sewer systems and treatment plants with measuring and regulation techniques
Minimizing sludge quantities
Research and development of processes for water supply and wastewater disposal for industries
Recycling of treated sewage
Elimination of resistant pollutants from water
Development of membrane-technologies for industrial and domestic treatment plants
Consulting in the planning of sewage treatment processes
Performance evaluation for plants and processes, e.g. measuring of oxygen supply

Solid Waste

Concepts for the disposal of domestic and industrial solid wastes (avoiding refuse, separate collection and reuse of wastes, composting and fermentation, incineration and pyrolysis, treatment of hazardous wastes, regulated land-filling)
Sanitation of old hazardous waste sites
Treatment of leachates and gases from landfills
Development of waste management concepts for industry and communes
Integrated systems for solid waste disposal in developing countries

Air

Development of processes for the biological treatment of polluted air (filters, bio-scrubbers, trickling filters and membrane reactors)
Development of measuring and sampling techniques for the analysis of air pollution (olfactometry and trace analysis)
Recording and identifying microorganisms in air from rooms and exhaust air
Microbiology and biochemistry of degradative and bio-transforming processes
