the two-stage activated sludge process (ab-process, i.e adsorption activated sludge process) invented by boehnke was successfully applied to several municipal and industrial wastewaters in korea. the first large wastewater treatment plant for the combined effluents of 22 textile dyeing companies was constructed in taegu and started operation in 1989. two years earlier pilot plant runs were performed. the ab-process proved to be superior to any other activated sludge process. bod was reduced from 1200 mg/l down to 24 mg/l. in the meantime in korea several further ab-process treatment plants were constructed, the overall planning and constructing period being not longer than one year.
