Abstract

Excess fluoride in drinking water is harmful for human health, so it is necessary to be removed. In this study thepotential of a reverse osmosis (RO)membrane for defluoridation of underground water samples at different solute concentrations was studied. Because of the variation in feed water composition, its chemical properties, pH and operating conditions, effect of these parameters on the membrane separation process was studied. The results showed that pH, feed water composition, flow rate and pressure affect the membrane efficiency, and thus proper control of these factors is essential for successful operation, Optimum membrane properties and proper rejection were determined percentage for the RO system to minimize the overall cost of water treatment. The samples were collected from three villages in the Gurgaon district and treated at optimized conditions. The results indicate that RO membranes can be successfully used for the treatment of underground water to the desired purity level, as they remove up to 95% of fluoride present in water and also take care of other ions present in water.

A systematic review on the investigation of optimal operating conditions of the reverse osmosis process in nitrate removal from drinking water
2024, Results in Engineering
During the last few decades, several global crises including limited water resources, massive contamination of water resources, and available water bodies with high TDS have made researchers use new and advanced technologies to improve water quality. Since RO technology is proven to be a capable method in the removal of both anions and cations from water, the current systematic review was conducted to evaluate the efficiency of RO to provide a suitable approach for managers and health officials to solve the problem of increasing nitrate concentrations in drinking water sources. 2743 articles and theses were included in the primary search. Following screening and final restrictions that took the goals of the review into account, 61 presented studies were chosen for coverage. Among the 61 selected articles and theses, 54% of studies were conducted on groundwater, 25% of studies used BW-high rejection membrane, 58% of studies used polyamide membrane, 59% of them used spiral wound modules. The mean concentration levels of NO₃ in the inlet-outlet and nitrate removal rate of the RO process were 145.7 and 20.8 mg/L and 85.03, respectively. Based on the proposed regression model, various variables including the type of environment to be treated, nitrate concentration at the inlet of the treatment system, the type of applied membranes, the area of the membranes and the pH value of the water showed a significant relationship with the concentration of nitrate at the outlet of the treatment system. The optimal conditions were the type of brackish water-low differential pressure membrane, the basic materials used for the manufacture of the membranes like polyamide/single-wall carbon nanotubes, the operating pressure of 5 bar, the area of the membrane of 2.6 m² at a pH of 7.
Polytetrafluoroethylene hollow fiber membranes with thru hydrophilic channels for enhancing water transfer and anti-oil-fouling properties
2024, Journal of Environmental Chemical Engineering
Herein, a feasible method for hydrophilic modification of polytetrafluoroethylene (PTFE) hollow fibers via interfacial polymerization (IP) was proposed. 1, 3-Diamino-2-propanol (DAP) and trimesoyl chloride (TMC) were selected as monomers and a three-time IP method was adopted to construct hydrophilic channels within the membrane pores, thus effectively improving the hydrophilicity and permeability of membranes. The solvent of aqueous phase in conventional IP process was replaced by ethanol for better introducing amine monomers into membrane pores. The characterization results of Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and water contact angle (WCA) tests indicated the successful formation of polyamide (PA) layer within the membrane pores. In comparison to the ethanol pre-wetted control membrane, the PTFE hollow fibers modified under optimal IP conditions exhibited higher water flux (from 136.8 to 1059.1 kg m⁻² h⁻¹) and showed better resistance to both BSA (FRR from 53.4% to 92.3%) and soybean oil (FRR 16.4% from to 78.1%) after four cycles of filtration and cleaning. Simultaneously, the modified membranes demonstrated a favorable oil removal capacity (≥ 92%), and still maintained good stability after 24 h ultrasonic treatment and 8 d immersion tests in acid, alkali and oxidation solutions. This membrane holds significant application value in the treatment of oily wastewater.
Polyacrylonitrile and polyethersulfone based co-axial electrospun nanofibers for fluoride removal from contaminated stream
2024, Chemosphere
Coaxial electrospun polyacrylonitrile (PAN) and polyethersulfone (PES) based nanofibers were prepared and was used for filtration of fluoride from drinking water for the first time. Well defined fiber geometry was obtained at 1 ml/h of core polymer, i.e., PES flow rate, 1.4 ml/h of shell polymer, i.e., PAN flow rate, voltage of 22 kV, while the distance between the needle tip and the collector was 15–17 cm. Increase in bead like structure in fiber strands was observed with higher PAN concentration, while it decreased for lower PES concentration, thereby giving an optimum composition (6 wt% PAN and 10 wt% PES) for uniform fiber morphology. This nanofiber, abbreviated as N2 acted as an ultrafiltration membrane having permeability in the lower range, i.e., 0.5 × 10⁻¹¹ m/s Pa and its fluoride removal efficacy was 46%. Fibers were also hydrophilic with considerable porous nature. Uptake of fluoride by this N2 nanofibers were evident from binding energy of 685.2 eV during XPS analysis. It is probable that nitrile and sulfone groups present in the core and shell of the nanofibers played an active in fluoride uptake, which was estimated as 110 mg/g at 298 K. Isoelectric point was in alkaline range which promoted negative fluoride ion uptake on positive nanofiber surface. Lead played higher masking effect in the uptake of fluoride in comparison to arsenic as coexisting ion. Dynamic cross flow filtration was also studied with this nanofiber in both synthetic and real life feed solution.
New nonporous fillers-based hybrid membranes for gas separations and water treatment process
2023, Current Trends and Future Developments on (Bio-) Membranes: Modern Approaches in Membrane Technology for Gas Separation and Water Treatment
Considering the superiority of membrane applications over traditional processes in answering the world’s call for energy saving and emission reduction, the chapter will only shrink the horizon and lay focus on nonporous fillers-based hybrid membranes fabrication strategies with lab-scale or in compliance with industry standards, its current trends and future possible applications in gas separation and wastewater treatment. We aim to provide in-depth reviews discussing new materials, characterization, and computational simulation, campaigning vigorously for opening innovative insights into the generation of zero-emission power technologies with high economic merits by examining the key points in these membranes.
Fluoride as a global groundwater contaminant
2023, Inorganic Contaminants and Radionuclides
Fluoride is essential for the human body and a global groundwater contaminant (the recommended WHO limit is 1.5 mg/L). The mobilization and genesis of fluoride depend on fluoride-bearing rocks (e.g., fluorite, fluor-apatite, biotite, etc.) that are a part of the natural geogenic process, which later contaminate the groundwater. More specifically, the dissolution process (via infiltration), lateral water flow, ion exchange, climatic factors, and chemical weathering of “rocks and minerals” are highly responsible for the release of elevated concentrations of fluoride in groundwater. The intake of fluoride-contaminated groundwater and anthropogenically produced daily usable products (e.g., dental products, foods, etc.) causes physiological and metabolic disturbances in animals and humans. However, this fluoride can be removed effectively from water by technology-enhanced processes (e.g., reverse osmosis, nano-filtration, coagulation, adsorption, electrochemical, membrane distillation, ion exchange, and precipitation). This, in turn, means that climate-dependent contamination, mobilization mechanism, and bioaccumulation will be essential for selecting efficient, cost-effective green technologies. Adequate information should be provided to overcome people’s wrong perceptions concerning fluoride-related issues, especially in lower socioeconomic groups. Policy interventions are required to improve the quality of life in the developing world, where there is a lack of awareness about health issues. Extensive research in this field can identify fluoride “hot spots” (through regular monitoring) and removal technique(s) utilizing public-private sector collaboration.
Performance prediction of a reverse osmosis unit using an optimized Long Short-term Memory model by hummingbird optimizer
2023, Process Safety and Environmental Protection
The accessibility to freshwater suitable for human use is a modern problem in many countries of the world. One of the well-known methods to overcome this problem is the reverse osmosis (RO). The performance of a reverse osmosis unit integrated to a recovery energy system was experimentally investigated under various operating system pressures (10, 15, 20, 25, 30, 35, 40, 45, 50, 55, and 60 bar) and recovery ratios (10%, 20%, 30%, 40%, and 50%). Moreover, a hybrid machine learning model composed of Long Short-term Memory (LSTM) neural network optimized by artificial hummingbirds’ algorithm (AHA) was developed to predict permeate flow and power saving of the investigated RO unit. The inputs of the models, in case of power saving, were recovery ratio and system pressure; while system pressure was the input of the models in case of permeate flow. AHA was employed to optimize the performance of pure LSTM via determining the optimal values of the model parameters. A considerable enhancement in prediction accuracy of the optimized model was observed compared with pure model. The coefficient of determination during testing phase of power saving prediction was 0.997 and 0.981 for LSTM-AHA and LSTM, respectively. While it was 0.992 and 0.97 for LSTM-AHA and LSTM, respectively, in case of permeate flow prediction. Furthermore, the saving in consumed power of the RO unit was declined with increasing the recovery ratio. Therefore, the best saving in consumed power was obtained for the recovery ratio of 10%, where it reported more than 85%.
