Analyzing the Waste
Prior to processing waste through the Evaporator, the waste is analyzed to determine its key constituents. This information is used to determine how the waste will behave both during and after the evaporation process, and to determine how much water can be safely removed from the waste.
If acceptable for processing, the waste is pumped into the evaporator from nearby double-shell tanks via double-walled underground transfer lines. It goes into a sealed vessel where atmospheric pressure is reduced and steam heat is applied, boiling the waste at only 125 degrees F., much lower than it would under normal pressure. When the waste reaches a designated thickness, called specific gravity, the waste is transferred to a double-shell tank for storage.
