The impact of industrial activity on ... - WASH Matters

Of greater concern than the actual volume of groundwater withdrawn by industry is the potential for negative impact of industry on the quality of the subsurface environment (WWAP, 2006). This is because the balance between the volume of water withdrawn and the much smaller volume actually consumed becomes wastewater or effluent to be disposed of.

volume of a given mass of particles depends on how closely they are packed. In practical terms, the bulk density of a powder tends to increase the more it is subjected to tapping, vibration or other action which causes particles to become better packed, with less void space between larger particles; this is known as the 'tapped bulk density'.

Whitby Jet: A Black Organic Gem, A Rock Similar to Coal

The result is a coal seam. Jet does not form in a seam. Instead, it forms when an individual piece of woody material such as a tree branch is washed into a body of water, becomes waterlogged, sinks to the bottom and is covered by organic-rich sediment. It is then compacted, degraded, and heated in isolation.

High Volatile Bituminous Coal - an overview ...

Upper Miocene peat deposited 17 mya and buried to depth of 5440 m at 140 °C in the Gulf of Mexico produced high-volatile bituminous coal (35–40% volatile matter (Stach et al., 1982)). Pennsylvanian peat deposited 270 mya at the same depth and temperature in the Ruhr Basin produced low-volatile bituminous coal (14.16% volatile matter).

How Coal Works | Union of Concerned Scientists

If coal is high in sulfur or other impurities, it is washed with a water or chemical bath, removing up to 40 percent of inorganic sulfur in the coal. Not all coal is prepared using the same process. High-sulfur coal commonly undergoes washing to meet environmental regulations, while low-sulfur coal is often crushed and resized without being washed.
