The overall objective of Reservoir Eutrophication: Preventive Management is to present the environmental and anthropogenic factors associated with the process of eutrophication and algal blooms in the Rio Verde reservoir and propose lake use and management technologies in order to minimize the problem. Eutrophication process in Rio Verde reservoir with the occurrence of intense algal blooms is a consequence of the interconnection of different climatological, hydrological, morphological, physico-chemical and biological factors, which occur not only in the watershed but also in the reservoir. Reservoir Eutrophication: Preventive Management compiles the information gathered from the development of a broad research program in Rio Verde watershed, from 2008 until 2010. Rio Verde reservoir, which was built in 1976, is located in the Metropolitan Region of Curitiba, capital of the state of Parana in South Brazil. This reservoir is mainly used for supplying water to one of PETROBRAS Refinery. However, the reservoir is to be used for supplying drinking water to the population and that is why better understanding this system dynamics is a great concern. The book is the result of an interdisciplinary research program, which has involved more than 150 researchers, with the aim of defining a watershed management preventive system in order to prevent eutrophication processes. This way, the book combines academic rigor with practical applicability and is of interest for both researchers and technologists working in watershed management. Reservoir Eutrophication: Preventive Management is of interest to researchers and technologists that wish to examine specific characteristics of tropical climates. It is of specific interest to developing countries and for researchers interested in knowing the developed methodology adapted for temperate conditions.

Sludge treatment and disposal is the sixth volume in the series Biological wastewater treatment. The book covers in a clear and didactic way the sludge characteristics, production, treatment (thickening, dewatering, stabilisation, pathogens removal) and disposal (land application for agricultural purposes, sanitary landfills, landfarming and other methods). Environmental and public health issues are also fully described. The Biological Wastewater Treatment series is based on the book Biological Wastewater Treatment in Warm Climate Regions and on a highly acclaimed set of best selling textbooks. This international version is comprised by six textbooks giving a state-of-the-art presentation of the science and technology of biological wastewater treatment. Other books in the Biological Wastewater Treatment series: Volume 1: Wastewater characteristics, treatment and disposal Volume 2: Basic principles of wastewater treatment Volume 3: Waste stabilisation ponds Volume 4: Anaerobic reactors Volume 5: Activated sludge and aerobic biofilm reactors Volume 6: Sludge treatment and disposal
