ABSTRACT:
A method for processing waste liquids, having high solids content. The process includes the steps of spraying and evaporating the waste liquid together with a dry gas in a counterflow of dry gas within a spray tower, collecting the solids of the waste water in a lower section of the spray tower, discharging the moist gas from an upper section of the spray tower, and bringing the moist gas in heat exchange with an evaporator of a refrigerating means to condensed the liquid from the evaporator. The cooled dry gas is directed in heat exchange with the condenser of said refrigerating means and heated to be returned in a closed loop to repeat the cycle of operation.
