  • Simultaneous treatment of SO.sub.2 containing stack gases and waste water
    Patent number: 4123355
    Abstract: A process for simultaneously removing sulfur dioxide from stack gases and the like and purifying waste water such as derived from domestic sewage in which a portion of the gas stream and a portion of the waste water, the latter containing dissolved iron and having an acidic pH, are contacted in a closed loop gas-liquid scrubbing zone to effect absorption of the sulfur dioxide into the waste water. A second portion of the gas stream and a second portion of the waste water are controlled in an open loop gas-liquid scrubbing zone, the second portion of the waste water containing a lesser amount of iron than the first portion of the waste water, contacting in the open loop scrubbing zone being sufficient to acidify the waste water which is then treated to remove solids originally present.
