Water reuse is a key agenda item for water management in the 21st century. The use of recycled water offers two highly significant advantages: first, it gives significant reduction of pollutant loading to nature (even zero emission); secondly, it provides a valuable new source of usable water, which is becoming ever more desirable as water stress affects numerous countries. For these strategic advantages to be realized, advancement of technology is crucial to promote the increase of the use of reclaimed water. The technology should be feasible, economical, and sustainable for public acceptance. The 5th International Conference on Wastewater Reclamation and Reuse was a major success in addressing these issues, with leading authorities from 44 countries making contributions to the wide-ranging programme. Following a full peer review 62 papers have been selected for publication in these proceedings.
Topics covered include: * Biofilm and membrane bioreactors * Filtration * Natural systems * Environmental nanotechnology * Micropollutants * Disinfection and oxidation * Health and risk assessment# * Treatment process monitoring * Regulation, policies and planning These proceedings report some of the very the best current work on reclamation and reuse technologies and clarify the policy context that enables their successful implementation.
