Abstract
The present invention provides a process for the management of H.sub.2 S containing gas streams and high alkalinity water streams in which process the H.sub.2 S is selectively removed from the gas stream and combusted to form an SO.sub.2 rich waste gas stream. The SO.sub.2 gas stream is then scrubbed with the water stream to substantially remove the SO.sub.2 from the gas while subsequent treatment of the water such as softening or settling is improved.
