This study aimed to investigate and develop a cost-effective and superhydrophobic ceramic membrane for direct contact membrane distillation (DCMD) applications. Two types of mullite-based composite membranes were prepared via extrusion and sintering techniques. To create a small and narrow pore diameter distribution on the membrane surface, the dip-coating technique with 1 µm alumina was employed. The hexadecyltrimethoxysilane eco-friendly grafting agent was adopted to modify low-cost multilayer mullite-based composite membranes, transforming them from hydrophilic to superhydrophobic. The prepared membranes were characterized via field emission scanning electron microscopy (FESEM), energy-dispersive spectrometry (EDS), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray diffraction (XRD), liquid entire pressure (LEP), contact angle, atomic force microscopy (AFM), porosity, and membrane permeability. The results of the prepared membranes validate the appropriateness of the material for membrane distillation applications. The optimized membrane, with a contact angle of 160° and LEP = 1.5 bar, was tested under DCMD using a 3.5 wt.% sodium chloride (NaCl) synthetic solution and Persian Gulf seawater as a feed. Based on the acquired results, an average permeate flux of 3.15 kg/(m2·h) and salt rejection (R%) of 99.62% were found for the 3.5 wt.% NaCl solution. Moreover, seawater desalination showed an average permeate flux of 2.37 kg/(m2·h) and salt rejection of 99.81% for a 20-h test without any pore wetting. Membrane distillation with a hydrophobic membrane decreased the turbidity of seawater by 93.13%.

Groundwater is a major source of drinking water for millions of people across the globe. Most of these sources are reported to contain elevated levels of arsenic. Human health and ecosystems are adversely affected by arsenic‐contaminated drinking water. So, arsenic‐contaminated groundwater has become a major global health concern. This paper reviews groundwater contamination sources and gives an outline of arsenic contamination in different places in Nepal. It also critically reviews the health hazards associated with arsenic poisoning. A comparative study has been made regarding different aspects of conventional and recent technologies, and the one that is the most suitable for remediation of contaminated water has been recommended.

“…At present, the existing studies about removal and detoxification of arsenic mainly focused on extraction and solidification/stabilization , methods. Some acid and organic reagents, such as H 2 SO 4 and citric acid, can be used to extract soluble metals and arsenide in mining slag and CFA, followed by membrane separation, , nanotechnology, adsorption technology, and electrochemical processes to separate arsenic from other elements contained in leachates. In addition, some novel adsorbents, such as iron-bearing or aluminum-based components, have been developed to trap arsenic. , For the solidification/stabilization of arsenic in CFA, , limestone, CFA-containing arsenic, calcium hydroxide, and other polymeric materials, such as polystyrene, were mixed in proportion to form a cement.…”

Every year, billions of tons of lignite are burnt to generate electricity, meanwhile generating large amounts of coal fly ash (CFA) that is regarded as an industrial waste. During lignite combustion, arsenic and scarce metals are simultaneously volatilized in the form of oxide into CFA. This study proposed an effective vacuum distillation method to remove As and recover Ge and W from CFA. The feasibility of separating As and recycling Ge and W from CFA was verified by the theoretical analysis. The experimental result indicated that the removal ratio of As was 96 ± 1% and the contents of Ge and W reached 0.75 ± 0.023 and 0.24 ± 0.016 wt % in the residue, which were enriched 17.2 and 1.2 times, respectively, at a temperature of 550 °C, with 50 wt % sulfurizing agent added under pressure of 1 Pa and 240 min of heating. For the condensed product, chemical species As 2 S 3 and As 4 S 4 were detected by X-ray photoelectron spectroscopy analysis. For Ge and W in the residue, GeO x (x < 2), GeS, WO x (x < 3), and WS 2 were the main chemical species. The potential mechanism involved in the release of arsenic from CFA, vacuum sulfurization, evaporation, and condensation was proposed. The kinetic analysis indicated that the apparent activation energy (E α ) was 31.24 kJ mol −1 . Those results encourage further exploration of vacuum separation technology to environmentally friendly recycle CFA.
