Recent years have seen significant developments in wastewater microbiology and in the application of population dynamics of mixed cultures to the design, control and operation of biological wastewater treatment systems. This attracted over 300 delegates to Berkeley for a high-quality programme, from which 97 papers have been selected for these proceedings. They cover a broad range of topics dealing with the microbiology of activated sludge and biofilms, including sessions on Microthrix parvicella, activated sludge microbiology and modelling, filamentous microorganisms, biopolymers, biochemistry, genetic methods, activated sludge foaming, and nutrient removal. There was particular interest in the use of genetic methods in determining the nature and distribution of microorganisms in activated sludge. New work on filamentous microorganisms causing hulking and foaming and on methods for solving these solids separation problems was also featured. These Proceedings highlighted some of the latest research in biological wastewater treatment processes. They will prove highly useful to microbiologists, environmental engineers, wastewater treatment plant operators and other specialists interested in biological wastewater treatment and water pollution control.

The International Water Association's 2nd World Water Congress held in Berlin in October 2001 was, like its predecessor, a resounding and well attended success. At the centre of its programme were over three hundred oral presentations addressing the drinking water, sanitation, stormwater and environmental needs of communities worldwide. From the large number of oral presentations, after full peer review, 60 papers dealing with aspects of wastewater treatment processes and sludge management have been selected for this issue. Topics include: treatment microbiology and particle separation; physicochemical treatment and industrial wastewater; biological nutrient removal (including process control); anaerobic treatment; physical-chemical techniques for nutrient removal from wastewater and membrane processes; process design; small wastewater treatment plants; sludge management, strategies and policies; and sludge treatment processes. With some of the world's leading experts as authors, highlighting the latest research results and their practical applications, these proceedings are an essential compilation of the latest advances relating to the whole wastewater treatment process, from fundamental treatment processes to sludge management practices.

The sustainable management of the Forest Industries challenges many different disciplines. Not only do the different forest industry sectors vary in the approaches needed, but the unique nature of mills and their surrounding environments create a huge variety of conditions and hence of strategies to be employed. Yet again the IAWQ's Forest Industry Wastewaters Symposium provided a forum for the world's leading experts to discuss the scientific and practical issues and report progress. The proceedings are introduced by 4 invited papers that examine the social, economic and ecological relationships of the forest industries and together with the concluding summary of the sessions and related panel discussion make plain the context in which the industries operate and can continue to improve their performance. The 42 selected papers cover: Process water treatment and recirculation Biological treatment Environmental effects Treatment and utilization of solids Studies of specific compounds and management of residuals and toxicity. These proceedings genuinely constitute a briefing on the state of the art and will prove invaluable to anyone involved as a researcher or a practitioner in the management of forest industry wastewaters.
