“…At the level of anion loads, higher removal of NO3 − and H2PO4 − in these closed systems than in the open system may be due to the fact that the more intensive growth of these crops resulted in a higher uptake of N [28] and P [29]. The percentages of nutrient removal in these water systems were lower than in the other systems, such as the soil treatment [30,31] or biofiltration systems [32] where the percentages of nutrient removal were higher than 50%, pointing out that the results obtained in so different environmental conditions are not directly comparable. On the other hand, the high potassium removal could be due to the high nutrient requirements of these crops and the lower removal of Na + , Ca 2+ and Mg 2+ compared to K + could be due to the antagonism between these cations under saline conditions as reported by Marschner [33].…”

Plants of Ruscus aculeatus, known as "butcher's broom", Maytenus senegalensis, known as "confetti tree", and Juncus acutus, known as "spiny rush" were grown in pots with a mixture of sphagnum peat-moss and Perlite in order to determine the effect and evolution over time of three water use systems on plant growth, water saving and nutrient uptake. These were an open system (irrigated with standard nutrient solution) and two closed systems (blended-water (drainage water blended with water of low electrical conductivity (EC)) and sequential reuse of drainage (sequential-reuse) water), over a period of 8 weeks. Irrigation with blended-and sequential-reuse-water increased the biomass of all three species at the end of the experiment, compared to the open system. Overall, sequential-reuse-water treatment maximised biomass production. The application of blendedand sequential-reuse-water allowed savings of 17% of water in comparison to the open system. Regarding Cl, NO 3 − and H 2 PO 4 − loads, there was a removal of 5%, 32% and 32%; respectively in the blended-water treatment and 15%, 17% and 17% in the sequential-reuse water treatment compared to the open system. For the cation loads (Na + , K + , Ca 2+ and Mg 2+ ) in these water treatments there was a removal of 10%, 32%, 7% and 18% respectively in the blended-water treatment, and 17%, 22%, 17% and 18% respectively in the sequential-reuse treatment, compared to the open system.

“…Moreover, the removal of NO 3 − is an additional benefit, especially in the Spanish Southeast, since it is an area classified as a nitrate vulnerable zone in accordance with the European Union Directive [31]. The percentages of nutrient removal in these water systems were lower than in the other systems such as the soil treatment [32,33] or the biofiltration systems [34], where the percentages of nutrient removal were higher than 50%, pointing out that the results obtained in such different environmental conditions are not directly comparable.…”

Abstract:The blending of drainage with water of low electrical conductivity and the sequential reuse of the drainage water are innovative technologies to manage salts in agricultural drainage. Plants of Cucumis melo were grown in coir grow bags, and Rosmarinus officinalis and Cacti spp. were grown in pots with a mixture of sphagnum peat-moss and perlite. In order to assess the effect and evolution over time of these water treatments on plant growth and water management and removal of nutrients, three water treatments were applied over a period of eight weeks. These were: (1) standard nutrient solution; (2) blended water treatment (drainage water blended with water of low electrical conductivity (EC)) and (3) sequential reuse of drainage water treatment. During the experimental growing period, samples of water supplies and drainages generated in each water treatment were collected weekly and from these data water volume and nutrient loads were calculated. At the end of the experiment, leaf fresh weight of rosemary plants decreased under the fertigation with the blended and sequential reuse water treatments. Nevertheless, the application of blended and sequentially reused water allowed for the saving of significant amounts of water and nutrients in comparison to the standard nutrient solution treatment. Considering these advantages, we strongly recommend the setting-up of these water treatments in areas with water scarcity such as in the Mediterranean Basin.

“…However, in most developing countries, especially in rural areas, these technologies are not adaptable, mainly because of expensive construction cost, complex operation, and maintenance . Recently, soil infiltration system has been gaining interests, such as the subsurface wastewater infiltration (SWI) and constructed rapid infiltration (CRI), due to their lower construction and operational costs, lower energy demands, simple management and maintenance, and higher effluent quality . Specifically, the constructed rapid infiltration systems (CRIS), which was developed from traditional rapid infiltration systems (RI), is a cost‐effective and technically appropriate alternative wastewater treatment process .…”

The treatments of swine wastewater with variable hydraulic loading rates (HLRs) and infiltrator structure were investigated using a modified two‐stage constructed rapid infiltration system (CRIS). Furthermore, microbial community distribution at different HLRs in the CRIS was also analyzed by high‐throughput sequencing. Results indicated that when the HLR was 5.44 cm/day and 10.88 cm/day, the removal rate of chemical oxygen demand (COD) was between 68% and 73%. However, the removal rate of COD dropped to 22.3% when the HLR increased to 16.33 cm/day. Compared to the small CRIS, the removal rate of NH3‐N was stable at about 78% in the large CRIS that had ventilation in the middle of the column. In addition, at HLR 11 cm/day, majority of the taxa detected in the CRIS were assigned to Proteobacteria, Firmicutes, and Bacteroidetes. Anaerobic ammonium oxidation occurred in the middle and lower parts of the columns of CRIS. When the HLR increased to 22 cm/day, the abundance of Planctomycetes decreased from 57.48% to 38.88% in the upper layer of the first column, whereas the abundance of Firmicutes increased from 6.8% to 16.17%. Results showed the microbial community shift was observed at different HLR, influencing the pollutants removal rate. © 2019 American Institute of Chemical Engineers Environ Prog, 38: e13218, 2019
