Wetland Systems for Water Pollution Control IX Selected Proceedings of the 9th IWA International Specialised Conference on Wetland Systems for Water Pollution Control, Held in Avignon, France, 26-30 September 2004 - Water Science and Technology

Selected Proceedings of the 9th IWA International Specialised Conference on Wetland Systems for Water Pollution Control, held in Avignon, France, 26-30 September 2004. Constructed wetlands and, in some countries, modified natural wetlands are widely used for the treatment of different types of wastewater.  Wetlands now have a record of good performance and reliability in applications that include sewage treatment for rural communities, farm effluents, urban and agricultural run-off, and sewage sludge dewatering. However there remains much work to be done in developing understanding of the mechanisms involved and clarifying the operational parameters and design methods that will optimise wetland performance. From the large, high-quality and wide-ranging programme of the Wetlands conference (including the joint sessions) these proceedings have been selected following peer review. They constitute an authoritative "state of the art" summary of current research into the use of wetlands for water pollution control and their successful applications worldwide.
