ABSTRACT:
A process and apparatus for treating and detoxifying salts-hydroxides scrubber wastes containing nitrite salts or sulfite salts so that the final product has low nitrite or sulfite content, a neutral pH and is usable either as a base blend or as a stand-alone liquid product for agricultural applications. One approach is to have a continuous flow oxidation of the waste solution by ozone followed by a neutralization step with MKP. Another approach is to perform oxidation and neutralization in one step by the addition of hydrogen peroxide and MKP.
