CIVL 1101 Introduction to Water Filtration

For example, a very fine sand retains floc, which also tends to shorten the filter run, while for a course sand the opposite would be true. Recent trends are toward coarse sands and dualmedia beds of anthracite overlying sand so that high rates of filtration can be obtained. A filter medium is defined by effective size and uniformity coefficient.

Rapid Sand Filters Water Treatment Process & Plant Design

The Rapid Sand Filter (RSF) water treatment equipment differs from the Slow Sand Filter water treatment equipment in a variety of ways, the most important of which are the much greater filtration rate and the ability to clean automatically using back washing.
