Many researchers and engineers have shown great interest in mass transfer processes produced by wind-induced waves. Such waves contribute significantly to the transfer of environmental materials, such as sediment and marine debris, and the turbulence occurring beneath the waves further complicates wave-induced mass transport. The phase cycle of wave motion is generally considered to be a key determinant of mean flow and turbulence. In aqueous environmental engineering, this relationship is a crucial one to investigate, since turbulence is closely related to mass transport. To address this question, we measured the time-series of instantaneous velocity vectors by means of particle image velocimetry in a laboratory flume to reveal the turbulence structure induced by wave motion. By using a wavelet analysis free of specific assumptions, we were able to decompose the instantaneous velocity data into mean current, wave motion, and turbulence components. This analysis allowed for the objective evaluation of the shear stresses related to wave energy and turbulence energy production. Furthermore, we found significant phase characteristics of energy transfer among mean velocity, wave, and turbulence components. In order to examine the diffusion and convection properties induced by wind waves, we also conducted tracking analysis of imaginary sediment markers. Our results support the conclusion that mass transfer induced by wind waves impacts the entire range of water depths, at least in relatively shallow aqueous environments.

Water conservation is vital to safeguard future water availability when natural resources like water become extremely scarce. It is fundamental to understand the significant determinants of water conservation activities which can also facilitate the implementation of appropriate policies for water demand management. Thus, the goal of this study was to determine the important social, psychological, and behavioral factors of water conservation behavior. A questionnaire survey was used to collect the data from 625 international students and employees from different universities in Japan. The structural equation modeling demonstrated that the proposed model explained 46% of the variation in water conservation behavior. Awareness of water issues was highly related to attitude, responsibility, and culture. Except for culture, attitude and responsibility were significantly connected with emotion. Finally, emotion, habit, culture and involvement were significantly and positively associated with water conservation behavior. These factors are incorporated for the first time in this study into a single model to better understand individual water conservation behavior. The sequential regression model showed that all determinants including demographic factors raised the variation's proportion by 53% in water conservation. Female participants had a significantly higher positive attitude, emotion, and water conservation behavior than male participants. Older participants exhibited higher levels of awareness, habit, culture, and water conservation behavior when compared to younger people. Lastly, participants believed that the most dominant component in water conservation behavior was the awareness of water issues. These findings could assist policymakers in raising household awareness, accountability, and involvement towards water conservation efforts.

Water contamination by ciprofloxacin (CIP) is a global and emerging issue because it increases the risk of infection by antimicrobial resistant bacteria. CIP removal from water by iron nanoparticles (Fe0) with the presence of oxalate hasn't been reported yet. The present study demonstrated that the addition of oxalate to Fe0 nanoparticles improved the removal of 100 mg L−1 of CIP from 45.04% to 95.74% under the following optimum conditions: [Fe0] = 0.3 g L−1, [oxalate] = 0.3 mM, initial pH = 7, and temperature = 25 ℃. Furthermore, the experimental results illustrated that high concentrations of dissolved oxygen in the aqueous solution greatly decreased the removal efficiency of CIP by (Fe0/oxalate) system from 97.69% (N2 atmosphere) to 67.47%. Similarly, the performance of (Fe0/oxalate) system declined from 95.43% to 85.23% because of increasing the ionic strength of the solution from 0 to 100 mM. In contrast, the influence of humic acid (0 – 40 mg L−1) on the removal of CIP by (Fe0/oxalate) system was neglectable. Also, the negative impact of coexisting ions on the competence of (Fe0/oxalate) system was in the following order: Mg2+ > NO3– > SO₄2- > Ca2+ > CO32– > K+. In addition, the desorption experiments and the results of SEM-EDS, XRD, and FTIR revealed that physisorption and chemisorption were responsible for CIP removal by (Fe0/oxalate) system as the addition of 0.3 mM of oxalate boosted the surface complexation between Fe0 nanoparticles and the carboxylic, ketone, and piperazinyl groups in CIP. These results were supported by the outcomes of kinetics, isotherm, and thermodynamic analysis. Moreover, oxalate addition significantly reduced the treatment cost of 1 L of 100 mg L−1 of CIP and the generated sludge by approximately 55.68% and 57%, respectively. Finally, this study proved that (Fe0/oxalate) system is inexpensive, practical, and more efficient than most of the reported Fe0-based systems with a maximum adsorption capacity of 294.66 mg g−1.

Chromium (VI) water contamination still represents a great risk to human health. Consequently, the need for unconventional adsorbents with remarkable sorption abilities is dramatically increasing. Hence, in this study, nickel hydroxide nanoplates (nNiHs) were developed to achieve rapid and significant Cr(VI) removal from aqueous solutions. nNiHs showed an average particle size and crystallite size of 36.8 nm and 8.68 nm, respectively. Different reaction parameters were investigated, including nNiHs dosage, pH, reaction temperature, initial Cr(VI) concentration, and co-existing anions. nNiHs could efficiently remove 20 mg/L Cr(VI) concentration over a wide pH and temperature range(s) (5.0–9.0) and (25–75 °C), respectively. Pseudo 2nd order kinetic model and Freundlich isotherm model were the best to fit experimental data. A maximum Cr(VI) sorption capacity of 71.25 mg/g was achieved at the optimal reaction conditions (pH 5.0, temperature 25 °C, and dosage 2 g/L), comparable to the previously reported values. The governing Cr(VI) removal mechanism by nNiHs involved the high dominance of electrostatic adsorption and the low dominance of co-precipitation. The high sorption potential of the nNiHs and the high affinity of the aqueous Cr(VI) species, enabled the proposed adsorbent to yield an efficient performance in binary environmental systems.

In this study, the reactive performance of magnesium hydroxide-coated iron nanoparticles (Fe @Mg(OH)2) was investigated for the removal of hexavalent chromium (Cr(VI)) from aqueous solutions. Short-and long-term progressive-release of Fe @Mg(OH)2 reactivity was evaluated through several batch tests. The Multi-functional effect of the environmentally-friendly Mg(OH)2 coating shell was represented by the progressive shell-dissolution in water and preventing the rapid corrosion of Fe-core, which resulted in a controlled release of Fe reactivity towards Cr(VI). Fe @Mg(OH)2 showed good performance in preserving Fe long-term reactivity within a wide range of pH (3.0-9.0) and temperature (15-55 oC). The long-term investigation of Fe @Mg(OH)2 performance towards Cr(VI) removal confirmed the progressive and maintained reactivity, represented by the continuous release of Fe electrons, to achieve 100% removal efficiency of 40 mg/L initial Cr(VI) concentration over 50 days reaction time, to be reported for the first time in the literature. Fe @Mg(OH)2 showed high regeneration abilities up to 5 cycles with 1.36 times average enhancement in Cr(VI) removal efficiency compared to that of Fe. Moreover, Fe @Mg(OH)2 achieved an increase in the shelf-live longevity performance up to 30 days without any storing solution with 90% final Cr(VI) removal efficiency after 180 min reaction time.

In response to the low efficiency of the anaerobic digestion (AD) process in generating methane gas, we apply for the first time the use of coated/Fe0 with Mg(OH)2 to enhance the production rate of methane gas from the degradation of waste sludge. A series of batch tests investigated several operations factors followed by a semi-continuous operation system examined the long-term production of methane gas in the presence of the coated/Fe0 were performed. The coating ratio of Mg(OH)2/Fe0 and the dosage of coated/Fe0 were optimized to acquire the highest production rate of methane as 0.5% and 25mg/gVS, respectively. Under these optimum conditions, the methane production increased by 46.6% in the batch tests and 120% in the semi-continuous operation system compared to the control reactor. The results revealed that both Fe0 and Mg(OH)2 did not significantly improve the production of methane when each one was used alone at different dosages, and the improved methane production originated from the synergetic effect of combining these two materials. The crucial role of Mg(OH)2 coating layer was associated with the controlled reactivity release of Fe0, which was indicated by the slow release of Fe2+ and Fe3+ in the bioreactors. Furthermore, the addition of coated/Fe0 stimulated bacterial growth, increased methane content, and maintained the pH within the optimum range in the bioreactors. The dosing time of coated/Fe0 was investigated during the four stages of AD process, and the best dosing time was found in the methanogenic stage (on Day 4). Overall, based on the experimental and predicted methane production, the coated/Fe0 has a great potential for the practical applications of AD.

In this study, calcined Mg-Al layered double hydroxide (Mg-Al-CLDH) was successfully synthesized for boron (B) removal from aqueous solutions. Batch experiments were conducted considering various reaction conditions, including initial pH, reaction temperature, initial B concentration, Mg-Al-CLDH dosage, ambient condition, and co-existing ions effect, for optimizing B removal efficiency. Results showed that sorption kinetic rate became higher by approaching towards the neutral pH conditions, while it declined at the strong acidic or alkaline conditions. Mg-Al-CLDH was capable of removing high B concentration (80 mg/L) from aqueous solutions at a reasonable dosage of 2 g/L, with a comparable sorption capacity (22.1 mg/g) to other reported studies. Moreover, high B removal rates were observed at high reaction temperatures, reflecting the endothermic nature of the reaction, and reached equilibrium within less than 6 h at temperature of 70 °C. Moreover, results of 3D-RSM modeling confirmed that the middle-high range of Mg-Al-CLDH dosage values was the suitable range to achieve high B removal efficiency, in spite of pH, temperature, and initial concentration effects. Furthermore, isotherm modeling confirmed that B removal by Mg-Al-CLDH occurred via a mono-layer sorption, and thermodynamic modeling revealed the positive value of entropy change, indicating that the randomness of the solid/liquid interaction increased within the adsorption process of B. Spent Mg-Al-CLDH showed great reusability performance by achieving 67%–75% B removal efficiency over three consecutive regeneration cycles, confirming the high potential and applicability of the presented adsorbent in real water treatment applications.

The antibiotic ciprofloxacin (CIP) is recognized as a contaminant of emerging concern because its persistent occurrence in water accelerates the growth of deadly antimicrobial resistance genes (AMRs). For the first time, the conventional precipitation technique was thermally modified to produce hybrid magnesium hydroxide/magnesium oxide nanorods [Mg(OH)2/MgO] for efficient and rapid adsorption of CIP from water. The successful synthesis of Mg(OH)2/MgO was confirmed by the outcomes of TEM, EDS, XRD, and FTIR analysis. Mg(OH)2/MgO exhibited an extraordinary capability to adsorb CIP from water regardless of CIP initial concentration where more than 97% of 200 mg L−1 of CIP was promptly eliminated within 30 min by 0.1 g L−1 of Mg(OH)2/MgO under neutral pH and room temperature. These results clearly state that Mg(OH)2/MgO is at least 2-fold efficient and 20-fold faster in removing CIP than the reported nanomaterials with exceptional adsorption capacity higher than 1789 mg g−1. FTIR analysis for the spent Mg(OH)2/MgO revealed that bridging complexation with carboxylic group and electrostatic attraction with the positive amine group are the responsible mechanisms for CIP adsorption by Mg(OH)2/MgO. Moreover, simulated CIP-contaminated river water was efficiently treated by Mg(OH)2/MgO which proves the promising performance of Mg(OH)2/MgO in field scale applications.

The rapid evolution of antimicrobial resistant genes (AMRs) in water resources is well correlated to the persistent occurrence of ciprofloxacin in water. For the first time, encapsulated nanoscale zerovalent iron (nZVI) with a shell of magnesium hydroxide (Mg/Fe0) was used to adsorb ciprofloxacin from water. Optimization of the removal conditions exhibited that 5% was the optimum mass ratio between magnesium hydroxide and nZVI [Mg(OH)2/nZVI)] as more than 96% of 100 mg L−1 of ciprofloxacin was removed. In addition, 0.5 g L−1 of Mg/Fe0 showed an extraordinary performance in removing ciprofloxacin over a wide range of pH (3–11) with removal efficiencies exceeded 90%. Kinetic analysis displayed that the kinetic data was well described by both Pseudo first-order and second-order models. Also, the equilibrium data was well fitted by Freundlich isotherm model. In addition, thermodynamic analysis evidenced that the removal of ciprofloxacin by Mg/Fe0 was exothermic, and spontaneous. The experiments also revealed that physisorption and chemisorption were the responsible mechanisms for ciprofloxacin removal. The proposed treatment system remediated 10 litters of 100 mg L−1 of ciprofloxacin solution with 100% overall removal efficiency. This treatment system could be a promising and practical solution to decrease ciprofloxacin concentration in different water bodies.

The development of antimicrobial resistance genes (AMRs) in water was globally accelerated due to the occurrence of ciprofloxacin (CIP) in water. This study aims to precipitate iron nanoparticles (Fe0) on the surface of titanium nanowires (TNWs) through a chemical process to overcome the limitations of Fe0 and efficiently remove CIP from water. TEM and XRD results confirmed the successful synthesis of Fe0 and TNWs. They also proved the successful deposition and dispersion of Fe0 on TNWs. Several (Fe0/TNW) nanocomposites were synthesised with different percentages of TNWs (5, 10, 20, 30, and 50%) to define the best TNWs ratio that will decrease the aggregation of Fe0 nanoparticles and achieve an outstanding removal efficiency of CIP. (Fe0/TNW) nanocomposite with 20% of TNW was nominated as the best nanocomposite because it demonstrated a promising performance, compared with other nanocomposites, by removing more than 67% of CIP with insignificant desorption behaviour during the treatment period (120 min). Dosage of (20%-Fe0/TNW), initial pH of CIP solution and reaction temperature were optimized through a group of batch experiments to efficiently remove CIP from water. The optimum removal of CIP was obtained by 1 g L-1 of (20%-Fe0/TNW) nanocomposite at initial pH of 7 under 35 °C.

The aim of the present study is developing a magnetic nanoscale zero-valent iron/zeolite (nZVI/Z) composite towards the efficient removal of ammonia-nitrogen (NH4+-N) from aqueous solutions. Series of batch experiments were conducted to investigate the effect of different factors on the removal efficiency, including pH effect, aerobic/anaerobic, NH4+-N initial concentration, and temperature. The mixing mass ratio of nZVI/Z was optimized to reach the optimal ratio (0.25 g nZVI: 0.75 g zeolite), corresponding to the best removal efficiency of 85.7% after 120 min of reaction. Results revealed that nZVI/Z is efficient for NH4+-N removal from water at a wide pH range (3.0–10.0), with superiority to the neutral conditions. Moreover, aerobic ambient and normal temperature of 25 °C were the optimal conditions for the removal process of NH4+-N. Removal mechanisms involved electrostatic attraction, ion exchange, and adsorption. Generally, nZVI/Z has great potential towards the practical applications of NH4+-N removal from water.
