Salinity reduction by Sarcocornia neei in hydroponics: implications in marine aquaculture wastewater remediation

Salinization has become one of the main environmental problems affecting worldwide ecological balance. The effluent discharge saline industrial effluents, such as marine aquaculture, and its rapid increase in global production last decades an important part this problem. halophyte Sarcocornia neei (Lag.) proven ability to remove assimilate nutrients from wastewater, making it a promising candidate for application phytoremediation systems. In study, reduce water salinity was evaluated. For purpose, plants were reared 53 days artificial effluents at four different salinities: A) 0, B) 10, C) 20, D) 30 g L-1. A significant salt reduction obtained all treatments with NaCl addition. maximum decrease achieved treatment C, reducing 6.91 ± 1.52 L-1, approximately 35% total added beginning trials. Plants tolerated content ranges; no mortality or stress symptoms observed any treatment. results are first approach suggesting that S. could be used bio-desalination wastewater. Further studies needed evaluate pilot systems integrated into effluents.
