“…Technologies are being developed to provide a source of income for impacted smallholder farmers to provide for water and food security. This include the desalination of brackish water and its use in an integrated production system involving reject brine for farm-raised fish and the use of fish-pond water to grow organic salt-tolerant vegetables and forage crops for small ruminants (Antas et al, 2019;Moura et al, 2016).…”

“…The amount of brine released depends on the quality of the raw water, as well as the effectiveness of the equipment used. If the brine solution is not disposed of properly, it has undesirable effects on the soil and the movement of salinity into waterways and underground stores [6]. Therefore, the main challenge for using reverse osmosis technology lies in how to dispose of the salt water or find a way to recover it to avoid unwanted effects on the environment [7].…”

An estimated 40% to 70% of the total water in desalination technologies is released as brine. In addition to high salinity concentrations, these liquid wastes contain different chemical components depending on the type and method of treatment. This brine causes a change in the marine environment due to its high ability to change the salinity, alkalinity and temperature of sea water, which affects the growth and size of aquatic life and disturbs marine diversity. There are several common methods for disposing of brine. These methods include sewer drainage, evaporation ponds, surface water drainage, deep well injection, and sprinkler irrigation. Evaporation and discharge methods into seawater are among the least expensive methods and are appropriate if appropriate conditions are available, such as a hot climate and spacious lands. The most efficient but most expensive method is zero liquid discharge. Whatever the method used, the main factor, in addition to the cost, is to reduce the environmental impact so that the discharge of brine waste does not cause a change in the marine environment or groundwater.

“…Old man saltbush (Atriplex nummularia) may be an alternative for improving fermentation patterns of silages within the forage preservation process due to its higher dry matter content associated with high salt contents, which can cause inhibition of the development of undesirable microorganisms by altering the pH and osmotic pressure of forage mass, thus improving its ensilability (MOURA et al, 2016).…”

This study aimed to evaluate the quality of leucaena, gliricidia, and pornunça silages with different levels of old man saltbush inclusion in their composition. A completely randomized design was used with five levels of old man saltbush (Atriplex nummularia) inclusion (0, 25, 50, 75, and 100%) in leucaena (Leucaena leucocephala), gliricidia (Gliricidia sepium), and pornunça (Manihot sp.) silages, with 5 replications per treatment, totaling 75 experimental mini-silos maintained in a covered shed and free of opportunistic animals. Silos were opened after 100 days of ensilage, and the silage of the first 15 cm of their ends was discarded. The remaining material was homogenized and sampled for determining the bromatological composition, in vitro digestibility, and fermentation profile. Old man saltbush inclusion levels in leucaena silages promoted a negative linear effect for dry matter, organic matter, crude protein, ethereal extract, pH, and ammoniacal nitrogen, while a positive linear effect was found for mineral matter, in vitro dry matter digestibility, total carbohydrates, non-fibrous carbohydrates, and propionic acid (P < 0.05). This silage also had a quadratic effect for lactic acid. Gliricidia silages showed a positive linear behavior for dry matter, mineral matter, and total carbohydrates, whereas organic matter, crude protein, and ethereal extract presented a negative linear behavior (P < 0.05). The contents of organic lactic, acetic, and propionic acids showed a quadratic effect for gliricidia silage as old man saltbush levels increased (P < 0.05). Regarding pornunça silage, dry matter, mineral matter, total carbohydrates, propionic acid, and butyric acid presented a linear increasing behavior, while organic matter, crude protein, ethereal extract, and non-fibrous carbohydrates presented a linear decreasing behavior (P < 0.05). Lactic acid and acetic acid concentrations for pornunça silage showed a quadratic behavior according to the increasing old man saltbush inclusion levels (P < 0.05). The highest contribution of old man saltbush in the silages promoted changes in the profile of organic acids, allowing an improvement in silage quality, favoring lactic fermentation rather than acetic fermentation. Butyric acid contents were low for all treatments and indicated the control of undesirable fermentation processes. These results indicate that old man saltbush inclusion in silage composition may contribute to bromatological composition and fermentation process of the studied silages.
