IWA-LWWTP - 2024
14th IWA Specialized Conference on the Design, Operation and Economics of Large Wastewater Treatment Plants. On behalf of the International Water Association (IWA) and its Specialist Group on Design, Operation and Costs of Large Wastewater Treatment Plants, it is our pleasure to invite you to join us for the IWA Specialised Conference “Design, Operation and Economics of Large Wastewater Treatment Plants”. The conferences on Large Wastewater Treatment Plants (LWWTP) are the most traditional specialised conferences organized by IWA specialist groups. The first conference (at that time called “workshop”) was held in Vienna and then was repeated in four-year periods in Vienna and since 1987 also in Budapest and Prague. This conference is the 14th conference in the series. The last conferences of the specialist group were held in Budapest (2011), Prague (2015) and Vienna (2020 postponed and finally cancelled due to COVID 19).
The conference will now come back to Budapest (September 2024) during a perfect time of the year.
The conference will focus on all aspects of the design and operation of large wastewater treatment plants including economic topics. It will also discuss research and technology for nutrient removal and recovery approaches. It will bring together operators, designers and consultants on one side with researchers, university teachers, life cycle analysis (LCA) specialists, developers, technology and equipment providers on the other side.
Special emphasis will be given to active participation of young water professionals. The conference will provide a forum for ideas and opinion exchange and for sharing practical experience spanning the whole range from design and operation of large wastewater treatment plants to concepts of wastewater management in “Cities of the Future”.
The scientific programme will be accompanied by a poster session. The poster session will provide a lively forum for discussion and idea exchange between conference participants and poster authors.
We cordially invite you to join us for this conference and are looking forward to an inspiring event.
The conference covers all relevant topics of IWAs Specialist Group on Design, Operation and Costs of Large Wastewater Treatment Plants.
To find proper solutions for problems related to design, operation and economics of large wastewater treatment plants is a task of steadily growing importance. While at the beginning of the 20th century only less than 15 % of the total population on the Globe lived in the towns, the estimates for 2050 predict about two thirds of all people living in the urban areas. Therefore, the wastewater treatment in large treatment plants is an inseparable part of water management of cities of the future. The operation of LWWTPs is more and more considered as a source of making valuables of the wastewater available for other purposes, e.g. water, energy or nutrients. Our traditional conference will also reflect this change in the paradigm in the topics discussed in Budapest.
1. Design and operation
- wastewater treatment in large cities and sensitive catchment areas
- selection of cost-effective solutions
- strategies for achieving low effluent nutrient level
- appropriate technologies for developing countries
- successful case studies
- CFD modelling
- control of activated sludge separation properties
- instrumentation, control & automation
- emission of N2O and other greenhouse gases
2. Management of wastewater services
- asset management and strategic planning
- benchmarking
- management, education and training
- regulation and governance
3. Sludge handling
- modern approaches to wastewater sludge processing
- activated sludge separation
- effect of reject water on wastewater treatment line
- treatment of sludge dewatering effluent (SDE)
- optimized use of energy from sludge
- energy recovery
- sewage sludge desintegration
4. Cost and energy optimization
- construction and investment
- cost and energy effective operation
5. Innovative wastewater treatment technologies
- mixing and aeration systems
- use of membranes in wastewater treatment
- removal of specific organic compounds (endocrine disruptors, micropollutants etc.)
- nutrient removal and recovery
- intensification of treatment (granular sludge, attached growth, hybrid systems)
- short cut nitrogen removal in mainstream
6. Large WWTP in “Cities of the Future”
- large WWTPs as basis for the future growth of cities
- water reuse
