Abstract

The present invention refers to a method and an apparatus for processing waste liquid, in particular industrial waste water of high solids content, characterized by the following steps:
a) spraying and evaporating the waste liquid together with a dry gas, in particular dry air in a counterflow of dry gas, in particular dry air in a spray tower, b) collecting the solids of the waste water in a lower section of the spray tower, c) 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,wherein the liquid condensed from the evaporator is collected, d) bringing the cooled dry gas in heat exchange with the condensor of said refrigerating means, and e) returning the heated dry gas in a closed loop to the method step a).
