The conference will focus on:

1. Overall case studies of large treatment plants

2. Design of (large) treatment plants

- Nutrient removal and recovery

- Optimising the interactions of wastewater treatment plant with sewer system

- Activated sludge separation

- Wastewater treatment plants in normal and sensitive catchment areas

- Achieving the Limit of Technology (LOT)

- Simulation modelling for process optimisation

- Applying CFD modelling for design

- Appropriate technologies for developing countries

3. Operation of (large) treatment plants

- Treatment performance

- Simulation and modelling for process optimisation

- Energy efficiency

- Odours and volatile emissions

- Instrumentation, control and automation

- Monitoring the performance of the processes

- Water reuse

4. Sludge handling and its effect on wastewater treatment

- Sludge stabilisation

- Sludge incineration

- Sludge disposal

- Sludge minimisation and disintegration

- Management of reject water

5. Costs and economics

- Cost optimisation of investment and operation

- Benchmarking

- Asset management

6. Advanced technologies for wastewater treatment

- Use of membranes in wastewater treatment

- Granular activated sludge

- Advanced oxidation processes (ozone, UV)

- Adsorption processes (activated carbon)

Additionally workshop or workshops are planned to be part of the programme. Candidate topics are:

• Challenges and perspectives of wastewater treatment in Central Europe;


• Utility management;


• Management of micropollutants on wastewater treatment plants – when, how and who will pay, and


• Wastewater treatment in fast growing cities – do we need new approaches?.
