Energy and services demand, such as the access to drinking water, focused on social and economic development to improve the well-being and health of the population, has seen an increase in recent years. Such pressure exerted in the last century on natural sources has provoked severe sustainable problems in our planet, where, for 2020 a 50% increase on water consumption is foreseen, as well as that 2/3 of the world’s population will live under hydric stress conditions. These concerns, in combination with the phenomenon of water scarcity, are also increasing in Europe, in the context of a higher drought risk as a clear consequence of climate change. Seventy percent of fresh water in the world is consumed by agriculture activities and 19% by industries, which makes it imperative to find new alternative sources of water, such as the reuse of treated urban wastewater as well as the recycling of industrial wastewater in own production processes.
When focusing on the advanced remediation of industrial wastewater for reusing purposes, a new generation of oxidation technologies must be investigated and developed in combination or integrated with other advanced biological or membrane-based processes after defining specific treatment strategies. The presence of microcontaminants and pathogens also hampers the reuse of urban wastewater treated with conventional biological processes for irrigation in agriculture. Consequently, the potential economic value of this particular water is decreased. This situation strongly calls for the development of remediation techniques to limit the release of these substances in the environment. A series of innovative processes and process combinations with great potential benefit compared to state-of-the-art water technologies must be developed. In both applications, it is crucial to be aware that many arid and semi-arid countries facing water scarcity are well positioned to receive sufficient UV radiation from natural sunlight yearly, enhancing the potential for solar decontamination and disinfection applications. If the use of a renewable energy resource minimizes operating costs, investment costs are largely dependent on technological choices that are to be incorporated as soon as the process design begins, and more particularly at the full scale reactor design step.
The aim of this Special Issue is to gather innovative and highly specialized new treatment technologies and their combination/integration with other advanced processes for the remediation and reuse of industrial and urban wastewater for different final applications, mainly in the own industrial production chain or for irrgation activities. The use of solar energy as a renewable energy will have special consideration, focusing on giving sustainable solutions always based on the green chemistry principle.

Abstract: Yangtze River Delta region is industrial developed with large population and intensive river networks. It undertakes part of the upper-middle reaches of Yangtze River pollutant transfer, and faces the water pollution of the region. It takes 40% of the country's industrial wastewater emissions, which results in grim task of water pollution governance. From the urban perspective, water pollution treatment is the fundamental way to solve the essences of water pollution in the region. This study uses data envelopment analysis method (DEA) to measure 17 major cities’ sewage disposal efficiency in the Yangtze River Delta in the years of 2004-2015. It finds out that 12 cities of water pollution governance achieved perfectly valid, but the rest of the 12 cities’water pollution governance scale efficiency or technical efficiency need to be improved. This study respectively draws a two-dimensional quadrant diagram of each city with the performance and efficiency performance. It gives teachcity’s urban sewage treatment ascension suggestion and policy recommendation.
Keywords: Yangtze River Delta; urban wastewater treatment efficiency; data envelope analysis

Abstract: This study is focused on Advances Oxidation Technologies (AOTs) using the combined effect of Fe(0─VI)/sulfite systems, that produce mainly SO4·− radicals, to remove different 4-aminobenzene sulfonamides (SAs), namely sulfamethazine, sulfadiazine, sulfamethizole, from aqueous solution. The results obtained showed that neither sulfite nor iron alone is able to degrade SAs, however the combined effect depends on the oxidation state of iron species whose effectiveness to activate sulfite to promote the degradation of SAs increased following this order: Fe(III) < Fe(II) < Fe(0) < Fe(VI). Using Fe(VI)/sulfite, the complete removal of SAs was obtained in 5 min largely surpassing the effectiveness of the other three systems. The sulfonamides removal percentage was markedly influenced by sulfite concentration and dissolved oxygen, which improve the generation of oxidant radicals. Response surface methodology was applied and a quadratic polynomial model was obtained which allows to determine the percentage of SAs degradation as a function of both the iron species and sulfite concentrations. Study of the influence of the water matrix on these AOTs revealed an inhibition of SAs removal percentage when using ground water. This is probably due to the presence of different anions such as HCO3−, Cl− and SO42− in relatively high concentrations. According to the byproducts identified, the proposed degradation pathways include hydroxylation, SO2 extrusion and different bond-cleavage processes. Cytotoxicity of degradation byproducts, using MTS assay with HEK 293 and J774 cells lines for first time, did not show an inhibition in cell proliferation, sustaining the safety of the process.
