“…Water treatment using zero valent metals (ZVM) in a reactor (or water body) [1][2][3][4][5][6], by aquifer injection/infiltration [7][8][9][10][11][12][13][14], or by placement in a permeable reactive barrier (PRB) located within an aquifer [15][16][17], results in an increase in water pH [5][6][7]18] and a change in water Eh [5][6][7]18]. This is accompanied by a change in water electrical conductivity (EC) [5][6][7]18] which is associated with: (i) the removal of cations and anions from the water by the ZVM (water treatment) [5][6][7]18]; (ii) dissolution of part of the ZVM into the water body [5,19].…”

Batch treatment of water (0.2 to 240 L) using Fe 0 (44,000-77,000 nm) in a diffusion environment operated (at −8 to 25 °C) using: (a) no external energy; (b) pressurized (<0.1 MPa) air; (c) pressurized (<0.1 MPa) acidic gas (CO2); (d) pressurized (<0.1 MPa) anoxic gas (N2); (e) pressurized (<0.1 MPa) anoxic, acidic, reducing gas (H2 + CO + CO2 + CH4 + N2), reduces the salinity of water. Desalination costs increase with increasing NaCl removal. The cost of reducing water salinity from: (i) 2.65 to 1.55 g·L . Desalination is accompanied by the removal, from the water, of one or more of: nitrate, chloride, fluoride, sulphate, phosphate, As, B, Ba, Ca, Cd, Co, Cu, Fe, Mg, Mn, Na, Ni, P, S, Si, Sr, Zn. The rate of desalination is enhanced by increasing temperatures and increasing HCO3 − /CO3 2− concentrations. The rate of desalination decreases with increasing SO4 2− removal under acidic, or pH neutral, operating conditions.

The olive oil industry in Palestine is an important and widely spread one and accomplished with the release of large amounts of olive-mills wastewater. This wastewater represents a significant environmental problem due to its high phenolic content. In this work, the photocatalytic degradation of the some phenolic compounds (gallic acid, oleuropein and resorcinol) present in olive-mills wastewater using the synthesized nanoparticles of mixed SnO2-MgO catalyst and solar irradiation was performed. The nanoparticles of mixed SnO2-MgO catalyst with different ratios were prepared by sol gel method using a modified procedure. The obtained particles were characterized by SEM and XRD. The particle size was determined as 4.32 ± 0.42 nm which is much smaller than those previously prepared by standard procedures. The degradation percentage of phenolic compounds was measured by UV spectrophotometry. The effect of time, catalyst amount and phenolic compound concentration on degradation efficiency was studied. The maximum degradation was achieved using SnO2-MgO (4:1) catalyst, 2.5 mg catalyst per 5 mL solution, within the time of 60-120 min and ranged from 51 to 90 % for different concentrations of phenolic compounds.Keywords: Photocatalytic degradation, Olive mill wastewater, Gallic acid, Resorcinol, Oleuropein.Asian Journal of Chemistry; Vol. 30, No. 9 (2018), 1994-1998 This is an open access journal, and articles are distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0) License, which allows others to copy and redistribute the material in any medium or format, remix, transform, and build upon the material, as long as appropriate credit is given and the new creations are licensed under the identical terms.
