This article relates the fundamental concepts of granular media filtration to the major factors influencing the overall quality of filtered water. In present-day theory, the particle removal mechanisms of transport, attachment, and detachment are described in two different modeling approaches: phenomenological theories; and trajectory theories. These theories are coupled with empirical evidence to stress the importance of chemical destabilization, initial degradation and filter ripening, minimization of rate changes, and the use of polymers for producing high quality water. Includes 52 references, figures.
