Sand / Media Specifications

2009-9-4  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.
