In advanced wastewater treatment, carbon is used to adsorb organic compounds, and in industrial wastewater treatment, it is used to adsorb toxic organic compounds. CARBTROL© C O R P O R A T I O N INTRODUCTION Carbon has been used as an adsorbent for centuries. One of the major attributes of activated carbon treatment is its ability to remove a wide variety of toxic organic compounds to non-detectable levels (99.99%). 2 Fundamentals of Adsorption onto Activated Carbon in Water and Wastewater Treatment 13 Özgür Aktas and Ferhan Çeçen. Activated carbon. 0000002483 00000 n Finally, the chapter discusses different mechanisms involved in the adsorption phenomena. endobj It is commonly used for the removal of various pollutants from water such as dyes and heavy metals [1; 2]. The commonly used adsorption processes include GAC and PAC. Carbon has been used as an adsorbent for centuries. Adsorption is most commonly implemented for the removal or low concentrations of non-degradable organic compounds from groundwater, drinking water preparation, process water or as tertiary cleansing after, for example, biological water purification. 0000004120 00000 n Read this book using Google Play Books app on your PC, android, iOS devices. 1.3.5 Improved Control of Pollutants through Integrated Adsorption and Biological Treatment 8. stream 0000018782 00000 n Immobilized biomass adsorbents offered outstanding performances. They elucidate the factors that influence the successful operation of integrated systems. 1.3.5 Improved Control of Pollutants through Integrated Adsorption and Biological Treatment 8.
