Performance of a Full Scale MBBR System for Biological Removal of Complex Nitrogen Compounds (Cyanide, Thiocyanate, and Ammonia) from a Cyanide Detoxification Effluent at a Gold Mine

Abstract

A 2 stage Moving Bed Biofilm Reactor (MBBR) system was installed at a gold mine to reduce the acute toxicity of the final effluent to rainbow trout and Daphnia magna. The first reactor was designed for cyanide, cyanate and thiocyanate oxidation to ammonia whilst the second reactor was designed for complete nitrification of the ammonia produced in the first stage reactor. The MBBRs have been in operation at design conditions for over 2 years, producing effluent which has consistently tested non-lethal to daphnia and rainbow trout following the initial commissioning period. The operation of the plant is described.
