ABSTRACT:
System and method for treating toxic washwater from ink, paint, pesticides and the like. The wash water is heated to a temperature on the order of 100.degree. F. in a sump positioned beneath a bed of horse manure media containing aerobic fungi and bacteria. Washwater is foam lifted from the sump to a level above the media and allowed to filter down through the media. Hot dry air is blown into the media from the side to maintain the media at a temperature on the order of 100.degree. F. and thereby promote microbiological activity and evaporation of the water in the media. Warm moist air from the media is cooled to condense the moisture, and the condensed moisture is collected as distilled water. A prefilter removes excessive amounts of solids from the washwater before it is introduced into the sump, and a Carnot cycle system provides the necessary heating and cooling for the water, media and air.
