“…Hence, reduce the hydrophobicity of the polymeric membrane. More so, Zhu et al [279] reported the state-of-the-art on the control of microbial fouling using different types of nanoparticles. Essentially, they pointed that nanoparticles such as fullerenes (C 60 ), Zinc based materials (ZIO-NM), silver-based particles (Ag-NM), grapheme oxide (GO-NM), and titanium dioxide (TiO 2 -NM), exhibit a strong antimicrobial effect.…”

“…While in the case of particulate fouling, the colloidal ions generated from the bulk mixed liquor are transported by convective and finally got deposited [51]. It is noteworthy that higher TMP encourage generation and agglomeration of ions, which subsequently got attracted to the unlike charged membrane surface to form scales layer [279]. The deposited and precipitated scale stratum of ions on the surface and pore wall of the membrane increases both hydraulic resistance and TMP.…”

Over the years, different types of alternative technologies have been developed and used for palm oil mill effluent (POME) treatment. Specifically, membrane bioreactor (MBR) has been employed to relegate pollutants contained in POME under different operating conditions, and the technology was found to be promising. The major challenge impeding the wider application of this technology is membrane fouling, which usually attracts high operating energy and running cost. In this regard, novel methods of mitigating membrane fouling through the treatment processes have been developed. Therefore, this review article specifically focuses on the recent treatment processes of POME using MBR, with particular emphasis on innovative processes conditions such as aerobic, anaerobic, and hybrid processing as well as their performance in relation to fouling minimization. Furthermore, the effects of sonication and thermophilic and mesophilic conditions on membrane blockage were critically reviewed. The types of foulants and fouling mechanism as influenced by different operating conditions were also analyzed censoriously.

“…Depending on the method of preparation, it can be built of one or several graphene layers, which affects its potential application. Chemical or thermal reduction of graphene oxide (GO) results in obtaining reduced graphene oxide (rGO), which, among others, has bactericidal properties [12][13][14][15]. The rGO sheets are heavily oxygenated with basal planes containing hydroxyl and epoxide functional groups, in addition to carbonyl and carboxyl groups located at the sheet edges ( Figure 1).…”

The paper presents a method of obtaining composite polyacrylonitrile-based (PAN) membranes with the addition of reduced graphene oxide (rGO). The membranes were obtained using phase inversion method from a homogeneous rGO dispersion in a solution of PAN dissolved in N, N-dimethylformamide (DMF). The impact of the amount of rGO addition to the PAN matrix on the physicochemical, structural, transport, and separation properties and on fouling resistance was studied. Composite membranes, due to the method of preparation used and the addition of rGO, are characterized by very good transport properties (~390 L/m2 h) and by a high degree of protein retention (85%). Reduced graphene oxide has biocidal properties, which, as we have shown, depend on the size of nanoparticles and the type of microorganism. rGO/PAN membranes, on the other hand, show biostatic properties against Gram-negative bacteria (Escherichia coli), Gram-positive bacteria (Staphylococcuc aureus) and fungi (Candida albicans). Thus, the obtained composite membranes can be potentially used in water disinfection.

“…The many techniques for coating water‐treatment membranes include dip coating, drop casting, and interfacial polymerization; however, there are no reports on inverse emulsion polymerization techniques. Emulsion polymerization is a process where radical chain polymerization takes place in oil‐in‐water systems comprising water, monomers, and surfactants.…”

This study reports on the benefits of an in situ interfacial dynamic inverse emulsion polymerization process under sonication of aniline in the presence of a commercial reverse osmosis (RO) membrane. This polymerization method is simple and much faster (5‐15 min) than systems reported in the literature. During polymerization, the membranes are coated with polyaniline (PANI) as verified by high‐resolution scanning electron microscopy (HRSEM) images and Fourier‐transform‐infrared (FTIR) measurements. A colony‐counting antimicrobial activity test showed that whereas the reference RO membrane developed a large bacterial colony, the polyaniline‐coated RO membrane had no colonies at all. Surface resistivity was the lowest when the pH levels were below 6, which corresponded to the polyaniline‐grafted conductive layer. The membrane flow properties were only modified slightly as a result of the polyaniline grafting, compared with a pristine reference membrane.
