Abstract:
A process for treating waste streams comprising:supplying a gaseous waste stream containing VOCs;moistening a biologically active column with a supply of wastewater, said wastewater being conditioned by pulsating said wastewater in the presence of sorbents and bio-solids, thereby bio-oxidizing microbes within the wastewater and further stripping volatile contaminants from the wastewater;passing said gaseous waste stream through said biologically active column of packing material;transferring said VOCs from said gaseous waste stream to said packing material;degrading said gaseous waste stream comprising VOCs and said wastewater contaminants by the bio-oxidation of microorganisms present within said packing material;and removing said degraded waste stream from said biologically active column;wherein said steps of supplying, passing, transferring, degrading and removing comprise the treating of said waste streams.
