Evaluation of Recycled Crushed Glass in Slow Sand Filtration

The effectiveness of a filter medium and slow sand filtration treatment of drinking water are site specific such that each filter medium must be evaluated on a case-by-case basis. 1 Cleasby, John L. “Source Water Quality and Pretreatment Options for Slow Sand Filters,” in Slow Sand Filtration, American Society of Civil Engineers, 1991.

Crushed rock, on the other hand, produces sand grains that are course, with jagged edges, and not uniform in size. Rounded sand grains of uniform size, when packed together, do not produce pore spaces small enough to be effective as sand filter media. Crushed rock sand grains, when packed together, fit like puzzle pieces.

The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging. KEYWORDS: sand/ media specifications, filter media, media grain size

How does a sand filter work Royal Brinkman

Feb 23, 2020 A sand filter, or sand water filter, makes use of sand to filter water. The water to be purified slowly sinks through the sand of the sand filter, leaving the dirt particles from the water behind in the fine pores of the sand. This filter technology is especially suitable for pre-filtration of disinfection equipment, preparation for micro- and
