Abstract
The objective of this research is to assess two treatability parameters, also designated, as various variables, fatores, hydraulic and operational configurations, which by hypothesis, potentially offer the influence of non-processing of wastewater quality (saline concentrate) from desalination. by reverse osmosis, through the application of Constructed Alagado Systems, cultivated with capim-elephant ( Pennisetum purpureum, Schum.). The studies were conducted on a bench scale, inside a semi-air-conditioned green house. Twelve experimental units have been made, and four treatment configurations have been established with three repetitions each, operated and monitored for five months, varying in function of the system's operation, of continuous flow or of static regime, and also no hydraulic stop time of three ou four days. Water samples collected at the inlet and outlet of each unit, were analyzed in the laboratory for physical-chemical characterization and monitoring of two parameters: pH, turbidity, salinity, hardness, calcium, chlorides, electrical conductivity, total dissolved solids. The results are submitted to the analysis of variance and Tukey's test, at a level of 95% confidence, using the statistical program SISVAR. The systems that are subjected to the static regime, with a hydraulic stop time of four days, after the first three weeks of operation, will prove to be more efficient in the removal of average salinity (53.1%), hardness (69.2%), calcium (66.7%). , chlorinate (44.5%), electrical conductivity (40.7%) and total dissolved solids (86.7%). As plants absorb Sodium in 0.25% of the weight of two total elements detected by electron microscopy of varredure in their roots.
