“…Salinity of 40-45 g/L appeared to induce severe mortality of the exposed plants, epifaunal mysids, and echinoderms [14]. After 96-hour exposure to 58‰ brine dilution, ascidians were the most sensitive species with more than 50% mortality, whereas a similar mortality rate was established in echinoids subjected to 85‰ brine dilutions for the same time period.…”

“…The increase of salinity can lead to a rise of water turbidity, which would prevent the penetration of light, disrupt the photosynthesis process [13], and cause growth retardation, tissue necrosis, and premature senescence of sea grass [14]. Salinity of 40-45 g/L appeared to induce severe mortality of the exposed plants, epifaunal mysids, and echinoderms [14].…”

“…The most widely utilized approach is the direct discharge into the sea, which causes a series of problems to the ambient seawater body by its influence on the salinity, temperature, turbidity, dissolved oxygen rates, and metal concentration. The release of concentrated saline with a high salt level, normally twice that of seawater [12,18], would result in dramatic ecological degradation, such as a substantial detriment to sea grass, plankton, invertebrates, and fish [10][11][12][13][14][15]22,25,26].…”

“…The whole world's seawater desalination capacity was 4.5 × 10 8 m 3 /day by the end of 2005, and this technology was widely used in the countries in the Persian Gulf, and by the Mediterranean and Red Sea [10]. One concern related to seawater desalination addresses the disposal of the concentrated saline, resulting from seawater desalination, which could cause serious environmental problems in the marine ecosystem [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. However, because the proportion of the constant chemical elements contained in the concentrated saline from seawater desalination and the seawater concentrated saline are almost the same, the usage of the concentrated liquid obtained from seawater desalination for the production of sea salt can be achieved [27].…”

Landsat images from 1979, 1988, 1999, 2008, and 2013 were used to analyze the landscape area change of salt pans lying on the coast of Tianjin. While initially (1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988), the area of Tianjin's salt pan increased, later it declined dramatically. In the first phase (1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987)(1988) of the studied period the primary roll-in landscape of the salt pan wasbarren land with an area of 60.0 km 2 . By 1988, the area of Tianjin's salt pan rose to 457.8 km 2 . The main roll-out landscape of the salt pan during 1988-2013 was urban, barren land, village/town, harbor, and road whose area amounted to 69.8, 35.9, 27.3, 25.5 and 18.4 km 2 respectively. The roll-out barren land will be transformed to construction land ultimately. By 2013, the total loss reached 167.3 km 2 , which was 36.5% of the salt pan area of Tianjin in 1988. With the development of coastal economy, the salterns with a lower economic value were transformed to and replaced by land use types with a higher economic value. This trend would influence the production of sea salt and the development of sodium hydroxide and sodium carbonate industries. Seawater desalination provides an opportunity for the restoration and compensation of salt production capacity. Based on the theory of circular economy and industrial symbiosis, in this article an industrial symbiosis model for sea salt production and sea water desalination is explored: "mariculture-power plant cooling-seawater desalination-Artemia culture-bromide extraction-sea salt production-salt chemical industry". OPEN ACCESSSustainability 2015, 7 10079Through the application of this process sustainable development of the sea salt production in Tianjin could be achieved.

“…In particular, the discharge of brine from desalination plants is one of the most investigated (see, for instance, Cipollina et al, 2004 [4]; Kikkert et al, 2007 [5], Besalduch et al, 2013 [6], Ferrari and Querzoli, 2015 [7], Crowe et al, 2016 [8], Nikiforakis et al, 2017 [9]), because of the concerns linked to the potential negative environmental impacts of the brine discharge (Campbell et al, 2005 [10]): this is mainly due to the increase in salinity which brine discharges impose on the receiving body, harmful to a lot of marine species, in particular to the Posidonia Oceanica (see Latorre, 2005 [11]; Sànchez-Lizaso et al, 2008 [12]). …”

An Investigation on the Effects of Different Stratifications on Negatively Buoyant Jets

Abstract. Negatively buoyant jets develop when fluids are released upwards into a lighter fluid or, vice versa, downwards into a heavier fluid. There are many engineering applications, such as the discharge, via submerged outfalls, of brine from desalination plants into the sea. Some concerns are raised about the potential negative environmental impacts of this discharge. The increase in salinity is the major cause for environmental impact, as it is very harmful to many marine species. The diffusers for brine discharge are typically inclined upwards, to increase the path before the brine reaches the sea bottom, as it tends to fall downwards driven by negative buoyancy. The negatively buoyant jet that develops conserves axisymmetry only when released vertically, so that it is not possible to use the well-known equations for axisymmetric jets. The main target of this paper is to investigate on a laboratory model the effects of different stratifications on the features of negatively buoyant jets. This has been done via a LIF (Light Induced Fluorescence) technique, testing various release angles on the horizontal and densimetric Froude numbers. Except for the initial stage, a different widening rate for the upper boundary and the lower boundary has been highlighted.
