The IWA Specialist Group in Wastewater Pond Technology promotes the sustainable use of waste stabilization ponds (WSP) for wastewater treatment in both industrialised and developing countries, and is delighted to invite you to their 11th IWA Specialist Group Conference on Wastewater Pond Technologies, which is organised by the University of Leeds in partnership with Aqua Enviro and with the support of water(at)leeds and the Institute for Public Health and Environmental Engineering.  This conference is one of the most important events gathering researchers and practitioners around the world, who work on the integration of ponds technology to a number of other wastewater treatment technologies.This international conference intends to make available the latest discoveries and proven technologies from pond systems, with the ultimate aim of achieving sustainable and affordable wastewater treatment systems.  Wastewater pond technology has made significant contribution to sewage treatment around the world by providing low-cost and effective treatment technologies.  Latest research and experiences in full-scale pond systems have examined treatment alternatives that might provide radical changes to how we currently treat wastewaters, both in industrialised and developing countries. In particular, this conference aims to promote the use of low-cost treatment technologies that provide added value from reducing operation and maintenance costs, while meeting stringent discharge water quality standards; and the recovery and reuse of resources from wastewater streams in the form of bioenergy generation, safe wastewater for reuse for agriculture, nutrient recovery and opportunities for novel chemicals from by-products.This conference will cover aspects of innovative pond technology applications for improving wastewater treatment systems, and in particular we will have presentations covering the following topics:Pathogen control and wastewater reuse in agricultureLand intensive, low-energy treatment options for small and rural communitiesAnaerobic wastewater treatment: where is it practical?Enhancing solids recovery from wastewaterAlternatives to methane for recovering the value of carbon in wastewatersInnovative products from screenings and gritThe applications of algae for nutrient recovery and biofuel productionEnergy and economic balances, what are the practical limits in resource recovery?Case studies for innovative pond technology developmentsThe potential for pond technology within The Nutrient FactoryPost treatment of effluent from anaerobic membranes and UASBs
