Abstract

A water treatment system is provided for removing contaminants from feed water. The system receives feed water at a stripper tower, which removes VOCs from the feed water and directs the VOCs to a heating stage to be eliminated. Hot gases are directed from the heating stage to an evaporation stage. The VOC-free water from the stripper tower is also directed to the evaporation stage. The hot gases are brought into contact with the VOC-free water and evaporates the water. The exhaust gases in the evaporation stage are vented. A slurry of precipitated solids and water are removed from the evaporation stage to be disposed of or directed to a decanter stage to separate the liquid portion of the slurry from the solids portion. The liquid portion can be directed back to the evaporation stage. The exhaust gases in the evaporation stage can also be recirculated to the stripper tower.
