An Introduction To Slow Sand Filtration
Figure 1.1: The basic design of a slow sand filter. There are several important elements that should be observed when constructing slow sand filters: • The raw water supply feeding the filter should be able to maintain a constant head of water above the filter bed, thus there will be a constant pressure pushing water through the filter1. The raw water source must therefore be able to supply
