Advances in Slow Sand and Biological Filtration

About this book

Slow sand filtration is credited with being the first drinking water treatment process utilised to improve the quality of water in both modern Europe and the USA. Within the last ten years, there has been a renaissance of interest in the potential use of slow sand filtration throughout the world, especially for small and rural communities and it continues to be the primary treatment process for many European cities. This volume provides physical, chemical, and biological perspectives on factors affecting the performance of biological filtration processes, from slow sand filtration to more advanced biological treatment techniques such as biological activated carbon (BAC).
