Carbonization of Sewage Sludge for Using as Adsorbents
Asian Journal of Chemistry,
Vol. 29 No. 1 (2017): Vol 29 Issue 1
Abstract
In this study, optimum conditions of sewage sludge carbonization for adsorbent production and qualities of carbonized sewage sludge as an adsorbents were discussed. In order to study the characteristics on digestion and surplus sewage sludge, proximate analysis (such as moisture, ash, combustibles, volatile matter and fixed carbon content), elemental analysis and calorific value analysis of wet sewage sludge were performed and dried. For the carbonized sewage sludge obtained through the change of carbonization conditions, BET, pore size and iodine adsorption performance tests were carried out to derive the optimum conditions of carbonization. As a result of the overall review on the fixed carbon content of dried sewage sludge and specific surface area (BET), pore size and iodine adsorption performance of carbonized sewage sludge obtained. It is difficult to produce the adsorbent with good adsorption performance, but low-quality adsorbent is regarded to be possible. In spite of disadvantages, in the view of the carbonization of the sewage sludge to produce an adsorbent, the optimum carbonization temperature was derived to be 350-450 °C and the optimum carbonization time to be 30-60 min.
