Optimising the performance of particulate adsorbents

Project: Research

Description

Current adsorbent technologies used in the removal of organics from aqueous wastes use granular activated carbon, resulting in the generation of significant amounts of secondary wastes and high material losses during thermal reactivation. An alternate process developed by Arvia Technologies utilises a proprietary graphite adsorbent with high conductivity and low adsorptive capacity, allowing adsorption equilibrium to be reached quickly and feed-stocks to be regenerated using a fast, low power electrochemical regeneration in a packed bed. The regeneration of the graphite adsorbent materials via an anodic oxidation is accompanied by surface deterioration and morphological changes to the graphite, the development of which ultimately limits the remediation cycle efficiency. This project seeks to improve understanding of the remediation input parameters, and thereby optimise process efficiency, through physical experiment, pilot rig operation and electrochemical measurements of graphite breakdown.
