Slow Sand Filters - SSWM

A slow sand filter (SSF) is a means of treating water for drinking water purposes and involves filtering water through a bed of 'media' (usually sand). It is simple in design, construction and operation. It consists of a tank inside of which lies a 'bed' of sand (i.e. media), supported by gravel, lying on a suitable
