Abstract
Some preliminary laboratory scale set-up results of adsorption process performance using different types of coal, as carbonaceous adsorbents, meaning powder activated charcoal (PAC), or granular activated charcoal (GAC) and mezotrophic peat (MP), applied for phenol and color removal from different high phenol-containing synthetic and real wastewaters were summarized. The influence of high phenol concentration in some adsorption processes applied for synthetic wastewaters (i.e. 10-3,000 mg/L phenol-containing solutions) and real wastewaters (i.e. wastewaters produced in manufacturing of wood fibrous plates, in a furniture processing plant, which was contained a known phenol concentration of 3,000 mg phenol/L) were studied in order to obtain a laboratory estimation of highest performance in phenol removal and its discoloration. The highest phenol removal efficiency, working with a dose of 50 g/L PAC, was of 99.875% in the case of 100 mg/L phenol-containing solutions, 80.70% in the case of 278 mg/L phenol-containing solutions with 50 g/L GAC, and 60.42% in the case of 2000 mg/L phenol-containing solutions with 50 mg/L MP. For the studied real wastewater containing around 3,000 mg/L phenol, the highest removal was of 73.46% for color with PAC, and 57.58% with MP, after 60 min (50.83% after 10 min), and of 95.19% phenol with PAC and 63.30% with MP, after 60 min. These data were useful in preparation of future experiments, andalso of in-deep adsorption mechanism characterization for high phenolcontaining industrial effluents, its optimization and industrial applications of adequate operating conditions.
