Membrane desalination does help at procuring an increasing freshwater (FW) global demand. Energy requirements of desalination technologies compromise the environmental sustainability of desalination. The integration of renewable energies with desalination technologies might improve the sustainability of desalinated water over other alternative FW sources.

The Environmental Sustainability Assessment of the adsorption and ion-exchange processes for arsenic removal
was the focus of this work. The pursued goals were to determine the impact of regenerating the activated alumina used as
adsorbent and the comparison of the environmental performance of two ion-exchange resins. Additional goals were the
comparison between the environmental performance of adsorption and ion-exchange processes and the evaluation of the effect of
integrating the proposed techniques on a water purification facility. The Life Cycle Inventory was obtained by means of
simplified models and simulation. In this work it was concluded that the removal of As(V) by adsorption consumed between 2
and 13 times more primary resources and created 3−17 times more environmental burdens than the ion-exchange process. The
integration of adsorption or ion-exchange technology in the drinking water plant would raise the primary consumption of energy,
materials, and water by 27−155%, 7−94%, and 0.48−5.3%, respectively. The increase in the environmental burdens was mainly
because of the generation of hazardous spent materials.

BACKGROUND: Under the current global energy scenario, the need for self-sustainable processes is encouraged. The photovoltaic solar powered electrochemical oxidation (PSEO) process has been developed to remove the organic matter from a lignosulfonate wastewater.RESULTS: An electrochemical reactor using boron-doped diamond electrodes, in a batch configuration, is directly supplied with current from a set of photovoltaic solar modules. Experimental results show that the process can oxidize about 90% of the total organic carbon (TOC) of the organic matter in the wastewater under the described operating conditions.CONCLUSION: The technical suitability of the PSEO process has been demonstrated. A model to relate solar irradiance and electrical current was applied and used in a kinetic expression which depends on solar irradiance to describe the removal of TOC.

Background, aim, and scope In order to assess the environmental sustainability of a novel wastewater treatment process based on power an electrochemical reactor by photovoltaic solar modules (photovoltaic solar electrochemical oxidation), a life cycle approach was considered to quantify the CO2 equivalent (CO2-eq.) emissions coming from the two supplying power systems to the electrochemical process: conventional grid power or photovoltaic solar power under Spain frame conditions. Materials and methods GaBi 4 software was used to build models to characterize the conventional grid and photovoltaic power generation (corresponding functional unit, 1 kWh). ecoinvent v2.0 was chosen to consider background data. Nine different 2030 scenarios were evaluated versus 2007 reference values to take into account: (a) the progressive change to a greener grid mix in Spain and (b) the improvements in photovoltaic solar technology. Results The results showed that, under the nine considered scenarios for 2030, the CO2-eq.per kilowatt hour emissions are always lower than the reference values for 2007 (reductions around 60%). Additionally, the results showed that 2030 values for the CO2-eq.per kilowatt hour emissions coming from the use of photovoltaic modules for power generation are expected to be around 60% lower than for 2007 values. Discussion In order to power an electrochemical process, the direct use of photovoltaic solar energy will give much lower CO2-eq.per kilowatt hour emissions than the supply from conventional grid. Conclusions A quantitative study based on life cycle assessment has compared the CO2-eq.per kilowatt hour emissions coming from supplying an electrochemical reactor by conventional grid and by photovoltaic solar modules under Spanish frame conditions and stated that the novel process photovoltaic solar electrochemical oxidation would be a preferred environmental option due to the lower CO2-eq.per kilowatt hour emissions under present and future scenarios. Recommendations and perspectives The results would suggest that it is worthy to explore not only the possibilities of this technology but also other electrochemical technologies that can be supplied directly by electricity in order to have a better sustainability performance.
