Integration of Bench and Pilot High Density Sludge (HDS) Treatment of Acid Rock Drainage (ARD) into Full-Scale Treatment Facility Design at the Central City/Clear Creek Superfund Site near Blackhawk, Colorado

摘要

The OU4 high density sludge (HDS) water treatment plant (WTP) was designed to treat flows ranging 180 to 600 gpm from four separate sources of mining influenced wastewater (MIW) within the Central City/Clear Creek Superfund Site near Blackhawk, Colorado. Successful HDS treatment process parameters were defined through bench and pilot-scale testing. Variation in scaled test results provided insight into the advantages and disadvantages of scaled testing and incorporation of scaled test results into full-scale WTP design.
