Extending granular activated carbon (GAC) bed life: A column study of in-situ chemical regeneration of pesticide loaded activated carbon for water treatment

Chemical Regeneration of Mixed‐Matrix Membranes for Micropollutant Removal from Wastewater

“…5. Similar results were achieved in the chemical regeneration of granular activated carbon by Larasati et al [91], who observed a decline of the performance to 36 % for pesticide removal after the fourth regeneration. The recovery of polymeric membranes with embedded mesomaterial after CBM adsorption with a 0.125 mol L -1 NH 4 OH solution resulted in a restoration of the removal capacity of 31.7 % and 55.4 % [25], which is similar to the results obtained in this study.…”

Urine as a Biobased Fertilizer: The Netherlands as Case Study

“…Many studies have investigated this, and it is possible to extend AC lifetime by steam, microwave, thermal and chemical means, among others. 51,[95][96][97] In some cases, adsorptive capacities were shown to be increased after regeneration. 96 Should the used AC become truly depleted however, incineration will likely prove necessary as is the case for AC used in hazardous contexts.…”

Application of activated carbon fabric for the removal of a recalcitrant pesticide from agricultural run-off

“…This research presents a novel use of AC fabric to develop highly porous filter structures that enable rapid passage of water through the media, while also providing adequate surface area and contact for adsorption to occur. This is particularly important for pesticides such as metaldehyde, where adsorption onto activated carbon is thermodynamically favourable but relatively weak, with a low negative delta Gibbs free energy (Larasati et al, 2022). To the authors' knowledge there has been no other research that has used AC fabric for this application, which has mainly been used for wound dressing, air filtration and for protective clothing for hazardous environments (Subranet et al, 2005).…”
