“…When released into seawater, BDs form a high-density plume that follows the bottom bathymetry. Saline plume dispersion varies significantly depending on effluent characteristics, such as desalination plant production, and BD disposal method (Fernández-torquemada et al, 2019;Fernández-Torquemada et al, 2009;Loya-Fernández et al, 2018;Petersen et al, 2019;Portillo et al, 2014a). In addition, BDs may contain the chemicals that are commonly used in desalination during pre-treatment and in the membrane and filter cleaning processes; these may include antiscalants, coagulants, antifouling agents, biocides, and antifoaming agents, which are all subsequently discharged with the BD (Lattemann and Höpner, 2008;Liu et al, 2013;Mezher et al, 2011;Portillo et al, 2014b).…”

The environmental impact of desalination is the most important concern related to its sustainable development. We present the results of a long-term environmental plan to monitor brine discharge (BD) from a desalination plant located in a high environmental value area in Spain. Generalized additive models were used to analyze the biological parameters of biological communities. Results of 17 years of BD monitoring show how its environmental impact can be minimized through well-planned decision-making between scientists and industry. The brine dilution prior to its discharge into an artificial channel of low ecological value significantly reduced the brine This is a previous version of the article published in

“…Teniendo en cuenta que los valores de E N obtenidos son coincidentes en orden de magnitud y tendencia (a mayor Ri N , menor E N ) con los valores resultado de la parametrización (15), que fue establecida a través de ensayos de corrientes bidimensionales, se puede concluir que efectivamente la región caracterizada como «estado normal» en el plano de simetría de estas corrientes de gravedad tiene comportamiento de pluma bidimensional, es decir, su principal mecanismo de mezcla es a través del flujo vertical. Además, comparando los valores de E N obtenidos para los casos experimentados en este estudio (tabla 4) se llega a la conclusión de que aquellos con mayores flujo de cantidad de movimiento M f (es decir, con mayores velocidades iniciales generadas por menores espesores iniciales y mayores caudales, CASO 2 y CASO 3) y mayores pendientes (CASO 4 y CASO 5) favorecen la dilución frente al caso base (CASO 1).…”

“…Tanto las corrientes de fondo hipersalinas como las turbidíti-cas han sido ampliamente estudiadas por la comunidad científica (desde [9] hasta [10][11]) bajo distintos enfoques: numérico [11][12], experimental [13][14] y de estudio de campo [15]. Muchos de estos estudios numéricos y experimentales se han centrado en el frente de la corriente y su esparcimiento [16][17], habitualmente generados por una descarga puntual controlada [10], mientras que otros analizan efectos tangibles en estas corrientes de amplio rango de escalas espaciales y temporales, como el efecto Coriolis [18].…”

“…Recently, the construction of desalination plants, which is one of the methods for solving this shortage, is increasing (Jones et al, 2019;Panagopoulos et al, 2019). There are various desalination methods, but reverse osmosis is the most widely used (Portillo et al, 2014;Qasim et al, 2019). Most of the reverse osmosis brine (brine), generated after desalination in a seawater desalination plant is discarded into the ocean.…”

Recently, research results on PC-based or alkali-activated slag cement (AASC) using seawater as mixing water have been reported. Unlike seawater, reverse osmosis brine (brine) is waste discharged into the ocean from seawater desalination plants. There is a need to develop new and effective methods of disposing or utilizing brine to reduce marine pollution, protect marine ecosystems, and increase marine plant construction. However, research on cement or concrete using brine as a mixing water is very limited. Brine has almost the same composition as seawater, and the ion concentration is 2–4 times higher. Therefore, it is believed that new methods of using brine can be investigated and developed based on existing research and experimental results on seawater. The effects of brine and aluminum oxide (AO) on activated slag with calcium hydroxide (CH) were investigated for hydration and mechanical properties. 5% and 10% of CH were used, and samples using fresh water (FC) were prepared at the same time for comparison with brine. The slag sample without CH has a low initial (1 and 3d) strength of about 10 MPa for both FC and brine, but increases rapidly from 7d. Incorporation of CH was effective in improving the mechanical performance of FC and brine samples. In addition, the brine sample exhibited higher strength than the FC sample because it formed fewer C3AH6 phases that cause volume instability than the FC sample and affected the hydration promotion of slag particles. And more calcite phases were observed in the brine samples than in the FC samples. Through this study, the possibility of using brine as a building material was confirmed. In addition, the effect of chloride ion adsorption of slag mixed with AO and CH on the physical properties and mechanical performance of the hydration reaction was confirmed.
