Review and Modelling of Hexavalent Chromium Removal Efficiency of Bio-Sorption and Activated Carbon for Waste Water Treatment abstract

Hexavalent chromium pollutants in water are the most challenging of human health according to current situations. From many treatment methods, the adsorption method is the best alternatives for hexavalent chromium removal from wastewater. Activated carbon and biosorption are the basic adsorbents in the adsorption process. In these review and model optimization there where many articles reviewed under activated carbons and biosorption without carbonizing. The basic factors for the two adsorbents are adsorbent dose, pH value, and contact time at around room temperature. Maximum removal efficiency allocated at the acidic condition, these show the –OH releasing state is at the acidic condition. According to articles reviewed, the efficiency of bio- sorbent was greater than activated carbon. There were similarity adsorption efficiency of activated carbon and biosorption. As reviewed activated carbon and biosorption preparation, activated carbon preparation was more energy consumption than biosorption preparations. The model optimization also summarised and optimum condition of maximum removal efficiency where specified.
