“…The term brine is used to define by-product waste of the seawater desalination process and is used for streams whose concentration exceeds 55 g/L [11]. Brine has always been considered, as mentioned, a pollutant by-product and various research studies have assessed the impacts of its improper discharge in coastal areas [12][13][14], the repercussions of intakes and outfalls [15], the effect on marine micro-organisms [16,17] and seagrass growth [18][19][20].…”

Throughout the last decades the developments on desalination field have been focused on energy consumption and costs reduction. However, water recovery and brine disposal are becoming a matter of concern to desalination industry. In this work, a Zero Liquid Discharge (ZLD) unit coupled with a Solar Micro Gas Turbine (SMGT) system is presented to address, among others, the challenges of mining industry in remote areas, in particular, fossil fuel dependence, water availability and pollution derived from effluents disposal. As a way to assess the feasibility of the proposal, a techno-economic analysis of the application in two Southern American regions (Chile and Ecuador) of photovoltaic modules, wind turbines and Solar Micro Gas Turbines is performed. Afterwards, the main novel feature of the new system—i.e., the ZLD unit—is described and a sensitivity analysis on its functioning whilst coupled with the SMGT is carried out. The aim is to propose a preliminary design of the ZLD process. The selection of the optimal ratio between exhaust gases and brine mass flow rates is analyzed, as well as variation in inlet salinity and temperatures. Furthermore, the water which could be recovered from effluents, at the same time that the heat of exhaust gases from SMGT is harvested, is quantified. Lastly, according to the results obtained, a preliminary design of a 10 kWe rated power SMGT system, coupled to Reverse Osmosis (RO) and ZLD units, is proposed.

“…O uso da terra decorrente da implantação da infraestrutura das usinas de dessalinização, como prédios, tanques de água, equipamentos de bombeamento e instalações de energia, é um impacto permanente (FUENTES-BARGUES, 2014). As instalações construídas alteram a estética da paisagem local e obstruem a passagem ao longo da costa, o que reduz o acesso público às praias e interrompe as atividades de recreação (HECK et al, 2016). Dependendo do local onde a usina de dessalinização é instalada, a remoção da cobertura vegetal costeira torna-se necessária, implicando redução de habitat (LIOR, 2017).…”

“…usinas de dessalinização de água do mar podem causar impacto significativo (direto ou indireto) no meio ambiente(GUDE, 2016). De maneira geral, os impactos ambientais causados por usinas de dessalinização de água do mar correspondem à alteração da paisagem(HECK et al, 2016), à redução de habitat (FUENTES-BARGUES, 2014), à sucção de animais durante a captação da água (LATTERMANN; HÖPNER, 2008), à poluição sonora devido às bombas(FUENTES-BARGUES, 2014;GUDE, 2016), à poluição e contaminação da água do mar devido à descarga do concentrado salino e dos resíduos do pré-tratamento (GUDE, 2016), dentre outros.…”

“…Such an assessment is critical to account for local preferences in the planning of desalination plants and to facilitate a more systematic approach to the planning of new facilities. While previous studies have investigated public attitudes towards desalination plants [24,30,41] and the acceptance of using desalinated water [19][20][21]65], an understanding of coastal stakeholders' management priorities for seawater desalination plants is lacking.…”

The development of seawater desalination plants to increase water reliability in coastal areas poses a threat to the health of near shore marine ecosystems and may affect the effectiveness of marine protected areas (MPAs) that have been established to meet international conservation targets. This paper applies a multi-criteria analysis approach to quantify stakeholder groups' priorities for seawater desalination plants that have been proposed in communities adjacent to a National Marine Sanctuary. All groups placed the highest importance on minimizing environmental impacts on protected areas and endangered species that could be affected by water intake and brine discharge emphasizing the need for integrated land and sea conservation. Minimizing socio-economic impacts on coastal communities was much less important. Stakeholders also weighted reducing pressure on water levels in rivers, streams, and aquifers as more important than increasing water for residential consumption, which may foster coastal growth rather than replacing water taken from other sources. The study further revealed differences in the importance of multiple management objectives among stakeholder groups, which highlights the need to elicit distinct priorities of all groups to understand concerns and potential conflicts of desalination with existing marine users. The analysis of consistency ratios revealed that around half of all surveyed stakeholders had high inconsistencies in their responses, which suggests either a lack of understanding of desalination, or reflects the complexity of establishing desalination plants in coastal areas adjacent to a marine protected area.
