Slow Sand Filtration For Community Water Supply In Developing Countries No-11 1978
A safe and convenient water supply is of paramount importance to human health and the well-being of society as a whole. A satisfactory water supply for domestic purposes, such as human consumption and personal hygiene, is characterized by adequate standards regarding the availability of water, its quantity, its quality and the reliability of the supply. Data collected periodically by international agencies show that a substantial part of the world's population, in particular a great many people in developing countries, do not have reasonable access to an adequate water supply. In recent years many efforts have been made to improve this situation.

Slow Sand Filtration 1974
The object of this volume is to discuss the various aspects of one particular form of water treatment--the “biological filtration” or “slow sand filtration” process. This system of water purification has been in continuous uses; - - the beginning of the nineteenth century, and has proved effective under widely differing circumstances. It is simple, inexpensive, and reliable and is still the chosen method of purifying water supplies for some of the cities of the world. A myth has grown up that this process is old-fashioned and therefore inefficient, that new techniques have rendered it obsolete, and that because it is simpler than many more recent innovations it is necessarily inferior to them.
