“…Concentrate disposal options are more limited for desalination of inland waters such as the Salton Sea, where ocean discharge is not feasible. If large-scale desalination of Salton Sea water is pursued, concentrate disposal must be addressed, regardless of the specific desalination technology selected [34,35]. Concentrate disposal options include well injection, evaporation ponds, or further concentration using vapor compression evaporation.…”

As freshwater sources of drinking water become limited, cities and urban areas must consider higher-salinity waters as potential sources of drinking water. The Salton Sea in the Imperial Valley of California has a very high salinity (43 ppt), total dissolved solids (70,000 mg/L), and color (1440 CU). Future wetlands and habitat restoration will have significant ecological benefits, but salinity levels will remain elevated. High salinity eutrophic waters, such as the Salton Sea, are difficult to treat, yet more desirable sources of drinking water are limited. The treatability of Salton Sea water for potential urban water use was evaluated here. Coagulation-sedimentation using aluminum chlorohydrate, ferric chloride, and alum proved to be relatively ineffective for lowering turbidity, with no clear optimum dose for any of the coagulants tested. Alum was most effective for color removal (28 percent) at a dose of 40 mg/L. Turbidity was removed effectively with 0.45 µm and 0.1 µm microfiltration. Bench tests of Salton Sea water using sea water reverse osmosis (SWRO) achieved initial contaminant rejections of 99 percent salinity, 97.7 percent conductivity, 98.6 percent total dissolved solids, 98.7 percent chloride, 65 percent sulfate, and 99.3 percent turbidity.

“…Aunque el uso de tecnologías de desalinización de agua de mar a nivel mundial ha aumentado significativamente en las últimas décadas y ha mostrado muchos beneficios en diferentes actividades humanas, se ha prestado poca atención al impacto del subproducto principal (agua de rechazo o salmuera) en los ecosistemas y especies (Gacía y Ballesteros 2001, Lattemann y Höpner 2007, Morillo et al 2014.

Palabras clave: ósmosis inversa, agua de rechazo, impacto ambiental RESUMEN Una alternativa para hacer frente al desabasto de agua para consumo humano, industrial y agrícola, es la desalinización de aguas marinas y salobres. Este proceso consiste en la separación de sales del agua mediante diversas tecnologías. Sin embargo, a pesar de los beneficios que ofrecen, una desventaja importante del proceso es la cantidad de salmuera generada y su impacto ambiental como resultado de su alta salinidad. Bajo este contexto, el objetivo de este estudio es realizar una comparación de técnicas de descarga para vertidos de salmueras producidas por una planta desalinizadora. Se propuso llevar a cabo la investigación de métodos de disposición, para proponer la técnica más adecuada que disminuya el impacto ambiental producido en la zona de estudio. Para ello, se operó una planta desalinizadora de 100 m 3 /d con recuperación del 85 % en agua producto y 15 % en agua de rechazo. Se comparó la diferencia de concentraciones de salinidad entre agua alimentación y rechazo (salmuera). Los resultados indican que hubo un aumento en la salinidad del agua rechazo respecto a la de alimentación (de 2931 mg/L hasta 6756 mg/L de sólidos disueltos totales). Este aumento en la concentración muestra que es importante regular o disponer el vertido de salmueras para evitar impactos negativos al ecosistema receptor. Para este proyecto el método más adecuado, según la zona de estudio, es operar una granja acuícola para producción de camarón con alto valor comercial. Esta propuesta se identificó para el control y el uso de vertidos de salmuera en la zona del Valle del Yaqui, Sonora, México.Key words: reverse osmosis, rejection water, environmental impact ABSTRACT One of the alternatives for tackling water shortages for human, industrial and agricultural use is desalination of seawater and brackish water. Desalination involves the separation of dissolved salts from water, by means of several technologies. However, despite the benefits that the technologies offer, an important disadvantage of the process is the amount of brine generated and its environmental impact as a result of its high salinity. In this context, the aim of this study is to compare the techniques available to discharge brines from a desalination plant, through the investigation of adequate disposal methods, in order to propose the best technique, to decrease the environmental Rev.

Abstract:Membrane engineering can offer an important contribution in realizing sustainable industrial development. It provides opportunities to redesign the conventional process of engineering in the logic of Process Intensification. Relatively new and less exploited membrane operations offer innovative solutions to the scarcity of raw materials, freshwater and energy. Here, we identify the most interesting aspects of membrane engineering in some strategic industrial sectors. Several cases of either successful or innovative membrane technologies are discussed.
