• History - Today
• The ISWA was already occupying itself in the
  Fifties with the problems of water quality, water
  supply, wastewater disposal and solid waste
  disposal, long before the investigation of
  environmental problems was common.
• Nowadays ISWA is an interdisciplinary institution
  within the Faculty of Civil Engineering of the
  University of Stuttgart and employs
• civil engineers,
• biologists,
• chemists,
• process engineers,
• geologists and geographers.

• The main objectives of the institute are
• teaching,
• research and
• the assistance of federal state ministries and
  agencies, communities and industries in solving
  practical problems.
• For example by means of
• pilot plant experiments,
• by working out the basic data and concepts for
  the planning and design of plants.
• With its 150 staff members - 6 of them professors
  and about 70 scientists yearly, ISWA is one of
  the largest of its kind in Europe

7

• 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.

8

• Water supply
• physical water treatment
• research on 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
• research on conserving water supplies and using
  storm water.

9

• Wastewater treatment
• treatment and transport of storm water flow
  concepts for drainage systems
• development of processes for nitrification,
  denitrification, biological and chemical removal
  of phosphorus
• minimising sludge quantities, recycling of
  treated sewage
• research and development of processes for water
  supply and wastewater disposal for industries
• elimination of resistant pollutants from water
• development of membrane-technologies
  (industrial/domestic)
• performance evaluation for plants/processes
• examination of small treatment systems.

10

• Solid waste
• concepts for the disposal of domestic and
  industrial solid wastes (avoiding refuse,
  separate collection and reuse of wastes,
  com-posting 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
• environmental technologies in tourism resorts.

11

• Air purification
• 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 micro-organisms in air
  from rooms and exhaust air
• microbiology and biochemistry of degradative and
  bio-transforming processes.

12

• Analytical and testing methods
• Development/use of measuring, analytical
  process control methods
• Chemical oxygen demand COD
• Sapromat (automated method for measuring
  biochemical O2 demand BOD)
• Denimat as method for measuring biochemical
  demand of nitrate
• Methanomat for measuring anaerobic degradation
  measuring adsorptive capacity of activated carbon
  for organic halogens and sulfur
• determination of carbon (TC, TOC) and nitrogen
  (TNb, Norg)
• Toximeter as forewarning instrument for toxic
  processes in activated sludge
• gas chromatography, HPLC, ion chromatography,
  mass spectrometry, coupled measurement GC-MS,
  HPLC-MS, CE-MS, tandem-mass spetrometry atomic
  absorption spectroscopy Fourier-transform-infrare
  d-spectrometry FT-IR extraction and
  chromatography with supercritical fluids ASE and
  SFC immunological and biochemical assays
  (ELISA) capillary electrophorese CE
  electro-chromatography fish tests toxic effects
  of sewage on fish test systems for determination
  of the degradation of plastics and bipolymeres.

• Equipment of the institute
• The institute has at its disposal numerous
  laboratories for
• the biological, chemical and physical analysis of
  water, wastewater, solid wastes and exhaust air
• necessary equipment for monitoring water works,
  domestic and industrial sewage treatment plants,
  solid waste disposal plants
• the examination of water quality of ground and
  surface waters
• fisheries research in inland waters and equipment
  for fish pathology.
• For semi-technical technical scale experiments
  the institute has at its disposal experimental
  halls with an area of about 800 m².

14

• One part of the institute is the sewage treatment
  plant which has been designed for teaching and
  research purposes.
• This plant system can be divided into two or more
  parallel streams in order to facilitate different
  treatment methods simultaneously.
• The wastewater comes from the suburban town
  Büsnau (about 3.000 inhabitants) and from the
  university campus.
