Title: Effect of biological and adsorption interactions on removal of organic material from synthetic-fuel waste water in batch and column systems

Abstract

The effect of temperature on total organic carbon removal from synthetic fuel waste water by activated carbon was evaluated, at temperatures of 5, 15, 25, and 40/sup 0/C. Both batch and continuous studies were performed using granular Darco H90 activated carbon, Calgon Filtrasorb 400, carbon black 2000, and glass beads as adsorbents for organics in Run-19, Run-20, Omega-9, oil shale retort water and Hanna 1VB-02W-02U coal gasification condensate. Experimental adsorption isotherms were compared with results predicted by the Langmuir and Freundlich models. Breakthrough curves were compared with curves predicted by the Thomas model. The rate controlling mechanisms in continuous flow adsorption system including second order reversible surface kinetics, external film resistance and internal particle resistance were also evaluated. Granular activated carbons coated with a bacterial film combining physical adsorption and biological removal of organics into one unit called adsorption/biodegradation unit were also investigated. This study included determination of bacterial numbers in batch and continuous flow systems at different heights in the column ad at different temperatures. In developing a modified Thomas model, which included the bacterial activity occurring inside the fixed-packed bed system, mass transfer coefficients were evaluated to establish the relative importance of various individual mechanisms that contributed tomore » the overall adsorption process. Biological film thickness was found to be a significant parameter in modeling the adsorption systems studied.« less
