Use of rotating biological contactors for treating coal gasification wastewater

Conference ·
OSTI ID:5207191
The two objectives of this study were to determine the feasibility of using Rotating Biological Contractors (RBC) for the treatment of coal gasification wastewater and to define a range of hydraulic and organic loadings for the reactors, within which process stability can be maintained. Despite a 50% increase in the hydraulic loading to the RBC the unit remained stable with only a 20% reduction in BOD/sub 5/ removal. The study showed that a RBC can achieve high biodegradable organic removal under the range of hydraulic and organic loadings tested. The RBC also proved to be stable during rapid fluctuations in thiocynate and cyanide loadings that upset activated sludge reactors being operated simultaneously with the same SGL.
