Abstract

"The objectives of this study was to determine the capabilities of selected types of activated carbon as an adsorbent for the removal of organic materials from municipal wastewater and sludges. The organic sources included primary and secondary clarifier effluent, blended sludge, and digester supernatant. Two other organic sources, glucose and alanine, were also examined to determine their removal from aqueous solution by activated carbon adsorption.

The organic impurities, in terms of chemical oxygen demand (COD), were reduced from 68 mg/1 in the primary effluent and 35 mg/1 in the secondary clarifier effluent to approximately 15 mg/1 for both. However, the organic impurities in the blended sludge and digester supernatant were reduced only about 25 percent by activated carbon adsorption, from approximately 2,000 mg/1 to 1,500 mg/1 and 1,100 mg/1 to 800 mg/1 COD, respectively. The D-glucose and a-alanine were removed at 70 and 75 percent, respectively. The use of pH adjustment in order to attempt the hydrolysis of organics in the samples to improve removal by carbon adsorption, the so called Zuckman-Molof, "Z-M", process, resulted in no significant improvement in the COD reduction by adsorption"-- Abstract, p. ii
