Clastic rocks, like sandstone, form from other rocks and minerals. Organic rocks, like limestone and coal, form from the bodies or shells of organisms. The Wentworth scale (also known as the UddenWentworth scale) is a logarithmic scale used in the United States that sorts rocks by grain size.

Anthracite is a select coal, mined and processed for use in water filtration. It is ideal for single bed, dual bed or multimedia filtration systems.

Coal. Coal is composed more or less of the element carbon, but (especially in the softer varieties) mixed with compounds of carbon. Firstclass anthracite coal is mostly carbon (up to 95%); it is amorphous, i. e., not crystalline. All varieties of coal contain noncombustible substances that are left behind as ash when the coal is burned.

Lignite is considered moderately available. Approximately 7 percent of the coal mined in the is lignite. It's found primarily in North Dakota (McLean, Mercer, and Oliver counties), Texas, Mississippi (Kemper County) and, to a lesser degree, Montana. The Lignite Energy Council notes that brown coal is more accessible than other types of coal.

of calcite dissolution depends on the pH, the partial pressure of CO2 (Pco2), and the activities of H2O, Ca2+, and HCOÿ 3 near the calcite surface (Plummer et al., 1979; Morse, 1983; Arakaki and Mucci, 1995). Generally, the overall rate of calcite dissolution will decrease as the pH and activities of Ca2+ and HCO 3 ÿ increase and the Pco2 decreases.

For increasing the pH of acidic water. Calcite dissolves as acidic water passes through and must be replaced as it dissolves. Unless it is used in an upflow filter, it must be backwashed.

The energy content of lignite consumed in the United States averages 15 MJ/kg (13 million BTU/ton), on the asreceived basis (, containing both inherent moisture and mineral matter). The energy content of lignite consumed in Victoria, Australia, averages MJ/kg ( million BTU/ton).

Coal is usually obvious to most students even though few people seem to have ever actually examined it up close. The dark brown to black color is the most obvious charateristic. Coquina and limestone are both composed of calcite .
