Filtration of surface water for use as drinking water has been a common practice since the inception of the water treatment plant. The earliest designs utilized combinations of sand and gravel which serve to greatly reduce the turbidity in the water.

Sand / Media Specifications

Media with small grain size slow the water movement and increase the chance of clogging. The effective size (D 10) and uniformity coefficient (Uc) are the principal characteristics of granular media treatment systems. The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm.
