“… Seven types of representative PFASs (Table S2) were spiked in the feedwater with a concentration of 20 μg/L for each compound. The pH of the feed water was adjusted to 6.0 for maintaining both high availabilities of nutrient ions for agricultural purposes and a dominant percentage (∼93.5%) of H 2 PO 4 – (with a smaller size than that of HPO 4 2– , which therefore can be more easily separated from PFASs with larger molecular sizes) among phosphate anions. , At least 6 h of filtration were performed before the feedwater, and permeates were sampled for ion and PFAS analyses. The permeate and concentrate of NF were recirculated back to the feed tank.…”

Efficient separation of harmful contaminants (e.g., per-and polyfluoroalkyl substances, PFASs) from valuable components (water and nutrients) is essential to the resource recovery from domestic wastewater for agricultural purposes. Such selective recovery requires precise separation at the angstrom scale. Although nanofiltration (NF) has the potential to achieve solute− solute separation, the state-of-the-art polyamide (PA) membranes are typically constrained by limited precision of solute−solute selectivity and their well-documented permeability−selectivity trade-off. Herein, we present a novel capillary-assisted interfacial polymerization (CAIP) approach to generate metal−organic framework (MOF)-PA nanocomposite membranes with reduced surface charges and more uniform pore sizes that favor solute selectivity by enhanced size exclusion. By uniquely regulating the PA− MOF interactions using the capillary force, CAIP results in effective exposure of MOF nanochannels on the membrane surface and a PA matrix with a high cross-linking gradient in the vertical direction, both of which contribute to an exceptional water permeance of ∼18.7 LMH/bar and an unprecedentedly high selectivity between nutrient ions and PFASs. Our CAIP approach breaks new ground for utilizing nanoparticles with nanochannels in fabricating the next-generation, fit-for-purpose NF membranes for improved solute− solute separations.

“…Over the years, hydroponics has been used sporadically throughout the world as a commercial means of growing both food and ornamental plants. Now at days, it has also been used as the standard methodology for plant biological researches in different disciplines [10]. Various modification of pure solution culture has been taken place over time throughout the world.…”

Sufficient agricultural water for irrigation is an important factor in food production, yet available fresh water only occupies 1% of the water on the earth. Seawater, through desalination, becomes rational solution to provide agricultural water due to abundant quantities and beneficial nutrients for crops. Hydroponic using desalinated seawater as medium is an approach to accomplish food security, especially in the arid and coastal areas. This study aimed to examine the growth of mustard (Brassica juncea L.) on a blend of fresh water and desalinated seawater using sulfuric acid activated zeolite as hydroponic medium. The experiment consisted of one control (100% fresh water+AB mix) and treatments namely a blend of 70% fresh water and 30% desalinated seawater using sulfuric acid activated zeolite with various sulfuric acid concentrations i.e 0.5, 1, 1.5, 2, 2.5, 3, and 3.5 N. The growth of mustard in blend of 70% fresh water and 30% desalinated seawater was lower than fresh water. A blend of 70% fresh water and 30% desalinated seawater using 1.5 N sulfuric acid activated zeolite showed no significant different mustard growth compared with fresh water medium and the fresh weight reduction was about 24%. Insignificant different growth between optimum treatment and control indicated a simple desalination method in this study can be utilized to desalinating seawater for hydroponic medium purpose. This finding emphasized that the simple seawater desalination method in this study for hydroponic medium was promising and interesting to be further developed for sustainable water management and agriculture.
