• Concept, design, start-up and operation of conventional and biological water treatment plants
• Innovative and practicable process engineering solutions for water treatment problems at mining and industrial sites world-wide
• Focussed on inorganic constituents such as metals, metalloids (e.g., arsenic), radio-nuclides and neutral salts (e.g. sulphates)
• Passive water treatment plants (constructed wetlands, reactive filter media, innovative biotechnological filter materials) with low operating costs for long-term tasks
• Removal of uranium from drinking water
