Selected Proceedings of the IWA International Conference, held in Kuala Lumpur, Malaysia, 29-31 October 2001. The IWA Conference on Water and Wastewater Management for Developing Countries was the first conference specially organized for developing countries after the merger between the International Association on Water Quality (IAWQ) and the International Water Services Association (IWSA). Its aim was to promote the concept of appropriate technologies for water and wastewater management, and to enhance linkages between institutions, practitioners and research groups working on low-cost treatment and waste recycling systems, and promote collaborative R&D. The outcome was a highly successful and well attended conference, with more than 300 participants from 21 countries. From this large and high quality programme (there were over 130 oral presentations), 42 articles have been selected after peer review. They cover the three major subject areas of the conference: operation and management; water supply and treatment; and wastewater technology. These proceedings thus contain not only the important details on the outcomes of the conference, but also demonstrate the significant advances being made in research and development on water and wastewater management in developing countries by researchers and practitioners, from developing and developed countries alike.

Part of Metals and Related Substances in Drinking Water Set - buy all five books together to save over 30%! The EU Drinking Water Directive sets a range of standards for metals and related substances in drinking water, many of which are concerned with health protection. A number of these standards are very stringent and require compliance to be assessed at the point of use. Because of the difficulties associated with monitoring, historic practices in many countries have concentrated on the quality of water within the distribution network. As a result, the magnitude of problems with some metals and related substances in drinking water is not fully appreciated in all European countries, and the extent and nature of corrective actions differ widely. This Best Practice Guide on Metals Removal From Drinking Water By Treatment describes drinking water standards and regulations, and explains the impact of a range of water treatment processes on metal levels in drinking water. Its objectives are to provide a basis for assessing the extent of problems and to identify appropriate water treatment options. The Guide provides a reasoned guide to selection of key water treatment processes. Each chapter focuses on a specific water treatment process and has been written by experts in that particular process. Best Practice Guide on Metals Removal From Drinking Water By Treatment provides practice-based knowledge for water engineers and scientists in large and small water utilities, regulatory agencies, health agencies and local municipalities (from cities through to small rural communities). It also supports university level teaching in degree schemes that relate to water management. This Guide is one of a series produced by the International Water Association’s Specialist Group on Metals and Related Substances in Drinking Water. The series is an up-to-date compilation of a range of scientific, engineering, regulatory and operational issues concerned with the control and removal of metals from drinking water.

This project develops a systematic performance testing protocol and specification for microfiltration (MF) and ultrafiltration (UF) membranes with respect to removal of viral and submicron bacterial pathogens. Both UF and MF have the capability to remove viruses (and submicron bacteria); however, the extent of removal is based on a number of factors including the membrane and the organism, as well as water quality and operational conditions. If membranes are to be employed on a more widespread basis for microbial removal, then their classification should be based on their ability to remove microorganisms, not on their nominal pore size. Rigorous microbial challenge studies at pilot scale are often prohibitively costly or considered hazardous. This report provides a peer-reviewed, standardized methodology with which to characterize membranes from a microbial perspective at bench scale, which is a benefit to both utilities and manufacturers. From a regulatory perspective, low pressure membranes are part of the microbial toolbox associated with the Long-Term 2 Enhanced Surface Water Treatment Rule. As a result of this project, bench-scale testing of Cyrptosporidum removal was included as methodology to evaluate new membrane products. It is important to note that the protocol was designed for both scientific rigor and ease of implementation.
