The process of underground coal gasification generates a waste water stream during the cooling and processing of the product gas. The character of the UCG condensate is similar to that produced by surface gasifiers, although there are some differences. The treatment options studied in this laboratory project were activated sludge treatment of raw condensate, activated sludge treatment of stripped condensate, and activated sludge with powdered activated carbon addition for treatment of stripped condensate. The condensates used were obtained from large-scale field tests in Wyoming. Major variables among the treatment options were the amount of dilution water needed to achieve stable operation, the degree of treatment achieved by each option, and the stability of the biological reactor.
