ABSTRACT:
The total organic carbon and oxygen in water may be reduced by adjusting the pH of the water to within the range of from about 4 to about 6.9 and then adding an excess of a reducing agent over the amount necessary to react with all of the organic carbon and oxygen present in the water. Preferably the water containing the reducing agent is passed over an adsorbent, absorbent activated carbon bed within a treatment unit the interior of which is anaerobic.
