Sludge is wet solids that results from the processing in municipal sewage systems. The sludge has to be dried before it can be composted. If a sludge containing 70% water and 30% solids is passed through a drier, and the resulting product contains 25% water, how much water is evaporated per ton of sludge sent to the drier.
