Abstract
A method for environmentally upgrading waste water containing formates, cyanides and ammonia is disclosed. Formates and cyanides are biodegraded by aerobic bacteria immobilized on the disks of a rotating disk contactor. Ammonia is air stripped. The present method eliminates the steam stripping stage of conventional processes as well as the lime addition and precipitation stages.
