METHOD FOR THE TREATMENT OF INDUSTRIAL WASTE

摘要

There is provided a method for treating spent metal working fluid (MWF), comprising the steps of: (a) providing a biofilm of microorganisms on a solid support matrix in a first bioreactor; (b) transferring at least a portion of the solid support matrix comprising the biofilm of microorganisms from the first bioreactor into a second bioreactor; and (c) incubating the microorganisms in the second bioreactor to reduce the chemical oxygen demand of the spent MWF contained therein.
