have through continuous extended exposure adapted to the treatment of these compounds.
Although cyanide is readily degraded by aerobic bacteria, thiocyanate is not readily
removed through anaerobic biological treatment. In addition, anaerobic biological treatment
is slower and more susceptible to toxic upsets resulting from exposure to other constituents
present in the solution being treated. As a result, the proper approach is to use an attached or
suspended growth aerobic biological treatment process for thiocyanate removal.
