As per the data provided by Coal India Limited(CIL), Heavy Media is the most suitable process of washing Indian origin coal because of the specific density of Indian coal which varies from 1.4 – 1.6 (approx). Hence it cannot be washed by the process which involves water as a principal media (as density of water is 1).

Some applications have experienced a moisture content as low as 7% with McLanahan Dewatering Screens, but final moisture content is dependent on both surface moisture and inherent moisture. When reporting moisture by weight (kg water/kg pulp), the specific gravity of the soilds also plays a factor, with higher specific gravity materials showing lower moisture contents.

Periodic washing of filters is necessary for the removal of accumulated solids. Inadequate cleaning permits the formation of permanent clumps, gradually decreasing filter capacity. If fouling is severe, the media must be cleaned chemically or replaced. For cleaning of rapid downflow filters, clean water is forced back up and through the media.
