Life-Cycle Assessment of a Coupled Advanced Oxidation-Biological Process for Wastewater Treatment: Comparison with Granular Activated Carbon Adsorption

Removal of organic compounds from water: life cycle environmental impacts and economic costs of the Arvia process compared to granulated activated carbon

“…LCI data on the reactivation of spent GAC are also available in various studies but the most detailed and complete inventories were found in Hutchinson (1975) and Meier (1997) as shown in Table 4. The data from these studies have been also used in other studies including Romero-Hernandez (2004), Muñoz et al (2007) and Gabarrell et al (2012). According to Chowdhury et al (2013), the GAC regeneration process typically requires 7e18 MJ of natural gas and 0.5e2 kg of steam.…”

Several studies have also examined the environmental impacts associated with specific treatment technologies or processes to remove organic contaminants such as GAC, nanofiltration, membrane filtration (RomeroHernandez, 2005;Bayer et al, 2005;Muñoz et al, 2007Muñoz et al, , 2009Marín et al, 2011;Bonton et al, 2012;Manda et al, 2014). The current study is the first to assess the LCA impacts and economic costs of the Arvia process.…”

Life cycle assessment of solar photo-Fenton and solar photoelectro-Fenton processes used for the degradation of aqueous α-methylphenylglycine

“…2 shows the relative contribution of several impact factors in scenario 9, something that can be extrapolated to all the SPF scenarios. Otherwise, Muñoz et al 16,27 carried out a LCA of a SPF wastewater treatment coupled with a biological treatment at industrial-scale with the same target substance (a-MPG) and they found similar behaviours both on the efficiency of the AOP and on the assessment of environmental impacts. Furthermore, the emissions subsystem also significantly affects the global warming potential (GWP) due to the CO 2 generated from a-MPG mineralization.…”

Performance of Wastewater Treatment Plants in Iraq: Life Cycle Assessment Approach

“…Although the use of LCA on wastewater management was covered by many studies during the last few years [12,13,14,15,16,17], there is still a need for more studies due to variation in spatial and temporal conditions on each case study, along with the difference in environmental concerns from one place to another. In developing countries, such studies can help evaluating the damages due to improper treatment.…”
