Product Description: The use of models in activated sludge design and operation is increasing, with a similar trend seen in education. Starting with the original IAWPRC Activated Sludge Model no 1 (ASM1) and the subsequent ASM2 and ASM2D, the first generation of activated sludge models have played an important role in practice...read more

Product Description: This Scientific and Technical Report (STR) presents the findings of the IWA Task Group on River Water Quality Modelling (RWQM). The task group was formed to create a scientific and technical base from which to formulate standardized, consistent river water quality models and guidelines for their implementation...read more

Product Description: The discipline of environmental engineering is young and rapidly evolving. Once viewed largely as a sub-set of civil engineering, with a particular focus on water sanitation, it has now grown to engage with all aspects of the human and terrestrial environment...read more

Product Description: The importance of marine pollution and effluent quality management has long been recognised in many parts of the world, particularly in the countries of the Middle East, with their arid climates and limited water resources. Industrial and municipal developments in the region along with changing lifestyles and increasing population, particularly in coastal communities, have resulted in many environmental pollution problems that require workable and affordable solutions...read more

Product Description: The fourth seminar in this well-established series on modelling of activated sludge processes gave an up-to-date overview of the status of modelling and the new developments in the field. The papers in this volume cover aspects of biomass and modelling, storage and hydrolysis, decay and maintenance, phosphorus precipitation and model development and calibration...read more

Product Description: "Sustainable development" has become one of the most widely expressed goals among the environmentally aware, particularly since the Brundtland Report and after Agenda 21 was agreed at the UN conference in Rio de Janeiro in 1992. However, the wide agreement on the importance of sustainability is not matched by any consensus on the meaning of the term or its practical implications for real engineering projects...read more

Product Description: Many problems arise from the wastes and effluents of agro-industries, and there is considerable interest in the solutions proposed or in use to tackle them. The 2nd International Symposium drew a large number of delegates to Istanbul to discuss acceptable approaches for waste management in agro-industries...read more

Product Description: Knowledge about the phenomena that govern the biological processes in wastewater treatment plants and more strict effluent criteria lead to continued research and developments in the field. Nitrogen and phosphorous removal processes which were not so long ago found in only a few treatment plants, are now a common feature of modern treatment plants all over the world...read more
