“…If Nyex 100 is electrochemically regenerated using cathode and anode, and salt. However, the adsorption isotherm was similar to when using fresh Nyex 100 (Brown et al, 2004). Adsorption isotherms were determined using Filtrasorb 400 (Chemviron Carbon) and two resins: Dowex Optipore L 493 (Dow Chemical Company) and Lewatit VP OC 1064 MD PH.…”

“…Nyex , contained above 90% carbon and had a particle size range of 100 to 700 µm [18][19][20][21][22][23]. The Nyex TM was washed with tap water several times prior to use.…”

“…The process uses a low capacity graphitic material (a graphite intercalation compound; Nyex TM (Cheshire, UK), a material comprising both graphitic edges and basal planes which are believed to provide a range of adsorption sites) as an effective adsorbent that can be rapidly and cost-effectively regenerated electrochemically [20][21][22]. Although a relatively low sorption capacity material, the lack of intra-granular porosity provides for both rapid sorption and regeneration kinetics, whilst the relatively high electrical conductivity means that electrochemical regeneration could potentially be carried out using relatively little energy [23].…”

Abstract:Metaldehyde is a selective pesticide applied to control snails and slugs and which, particularly when application rates are high and during periods of high rainfall, may find its way into water courses, some of which may be used as drinking water supplies. Existing water treatment processes have been inadequate for reducing metaldehyde residual levels (up to 8 µg/L) found in some waters to below the EU/UK statutory limit of 0.1 µg/L. Here a novel coupled adsorption and electrochemical regeneration technology is tested to determine if it is capable of effectively removing metaldehyde. We demonstrate that metaldehyde is not only adsorbed on the adsorbent used but is also destroyed during the regeneration stage, resulting in residual metaldehyde concentrations below the EU/UK regulatory limit for drinking water. No known harmful breakdown by-products were observed to be generated by the process. The effectiveness of the process seems unaffected by organic-rich peat water, indicating the potential for the treatment of drinking water much of which in the UK is derived from upland peaty catchments. Furthermore, successive spiking experiments showed that this technology has the potential to be applied as a continuous process without the generation of substantial waste products.

Abstract-Arvia™ introduced a novel technology consisting of adsorption followed by electrochemical regeneration with a graphite intercalation compound adsorbent that takes place in a single unit. The adsorbed species may lead to the formation of intermediate by-products products due to incomplete mineralization during electrochemical regeneration. Therefore, the investigation of breakdown products due to incomplete oxidation is of great concern regarding the commercial applications of this process. In the present paper, the formation of the chlorinated breakdown products during continuous process of adsorption and electrochemical regeneration based on a graphite intercalation compound adsorbent has been investigated.
