Eliminierung von Abwasserinhaltsstoffen durch Kombination biochemischer und grenzflächenchemischer Mechanismen

Recent developments and future trends of waste water treatment by combined biochemical and adsorptive elimination steps are presented. Various mechanisms are discussed to explain the enhancement of conventional activated sludge systems by addition of different solid adsorbents. Special emphasis is given to the improvement of elimination capacity and operation stability caused by powdered or granular activated carbons. The results of laboratory experiments as well as large-scale applications suggest that combinations of biological systems with by-product carbonaceous materials are most likely to gain future importance in waste water treatment facilities.
