Coal washing is a process that is undertaken in a coal washery or coal preparation plant (CPP) where coal is refined or cleaned of impurities. Coal washing involves using water, mechanical techniques and relies on gravity and the difference of density between coal and it's impurities which are usually more densely packed due to the fact that they are inorganic.

This refers to 15ppm oily water filtering equipment which is not fitted to dry cargo ships for use with cargo washings Because of the large quantities of water used in hold washing and relatively low amounts of petroleum content the washings are unlikely to exceed 15ppm; but it would be prudent to take a sample of effluent and ensure that the content is less than the 15ppm, and then dispose of ...
