“…However, judging from the flux value, HH2.0 shows the best performance by showing the highest flux and almost complete fouling reversibility. A similar study done by previous researchers that employed HNT and Fe 2 O 3 as additives in a polymer membrane has reported only up to 97% antifouling efficacy on the modified membrane [51][52][53][54]. Figure 6 shows that the pristine PES membrane has the lowest reversible fouling ratio but the highest irreversible fouling with comparable total fouling to other HNT-HFO blended membranes.…”

Membrane filtration is an attractive process in water and wastewater treatment, but largely restricted by membrane fouling. In this study, the membrane fouling issue is addressed by developing polyethersulfone (PES)-based mixed matrix membranes (MMMs) with the incorporation of hydrophilic nanoparticles as an additive. Ultrafiltration MMMs were successfully fabricated by incorporating different loadings of halloysite nanotube-ferrihydrates (HNT-HFO) into a polyethersulfone (PES) matrix and their performance was evaluated for the separation of bovine serum albumin (BSA) solution and oil/water emulsion. The results show that wettability is endowed to the membrane by introducing the additive aided by the presence of abundant -OH groups from the HFO. The loading of additive also leads to more heterogeneous surface morphology and higher pure water fluxes (516.33–640.82 L/m2h) more than twice that of the pristine membrane as reference (34.69 L/m2h) without affecting the rejection. The MMMs also provide much enhanced antifouling properties. The filtration results indicate that the flux recovery ratio of the modified membrane reached 100% by washing with only distilled water and a total flux recovery ratio of >98% ± 0.0471 for HNT-HFO-loaded membranes in comparison with 59% ± 0.0169 for pristine PES membrane.

This oily wastewater has severe adverse effects on the environment, as previously witnessed during several oil spill accidents in the marine and terrestrial environments due to oil leakage from petroleum transport pipelines, storage tanks or transport facilities, and blowouts in oil wells. [3] The treatment of oily wastewater can be performed via numerous technologies such as adsorption, [4] dissolved air flotation, [5] coagulation, [6] gravity separation, [7] and biological treatment. [8] However, these methods have several limitations, such as low removal efficacy, high operational cost, high energy consumption, corrosion, and production of contaminated solid waste from spent adsorbents. [9] The rapid growth in separation technologies has resulted in various membranes that could overcome the shortcomings of other treatment methods. [10] Thus, membranes have become more desirable for oil/water separation for industrial applications because of their small footprint, environmental friendliness, cost-effectiveness, high productivity, low chemical consumption, automation capability, steady operation, and excellent separation efficiency. [11] Indeed, pore blockage or fouling remains among the major obstacles facing the membrane separation process since it decreases the flux, restricts the permeation rate, increases the energy consumption, and decreases the membrane lifetime. Therefore, substantial research efforts have been focused on enhancing the properties of membranes either via developing novel materials or introducing surface modifications for conventional membranes. [12,13] Although few reviews were published on oil/water separation membranes, they are either outdated or focused on a specific membrane type. This review features the most recent progress in membrane separation and its practical application in oil/water separation. It includes four sections that cover essential factors related to the advancement in membrane technologies are highlighted, including: 1) membrane properties and characterization for oily waste water separation; 2) the employed materials to fabricate membranes (i.e., metallic, organic, inorganic, and hybrid materials), 3) primary methods for designing membranes (i.e., mixed matrix nanocomposites and multilayers nanocomposites), and 4) membrane fabrication techniques and surface modification methods. Membrane Properties and CharacterizationThe main objective of the oil/water separation membrane is to achieve high separation efficiency and excellent performance.Recent advancements in separation and membrane technologies have shown a great potential in removing oil from wastewaters effectively. In addition, the capabilities have improved to fabricate membranes with tunable properties in terms of their wettability, permeability, antifouling, and mechanical properties that govern the treatment of oily wastewaters. Herein, authors have critically reviewed the literature on membrane technology for oil/water separation with a specific focus on: 1) membrane properties and characterization, 2) d...

The need for nontoxic antifouling coatings has encouraged material scientists to develop a class of organic coatings for diverse applications. As a versatile thermosetting resin and well known for coating application, antifouling characteristics have been integrated into epoxy along with anticorrosion and adhesive functions. Accordingly, both micro-and macro-biofoulings have been successfully controlled by using epoxy-based antifouling coatings. Epoxy nanocomposites, silicon-grafted epoxy, epoxy-aided conductive polymer blends, and nanocomposites are important antifouling epoxy variants far and wide examined in developing epoxy-based coatings. Besides, some purpose-specific multifunctional smart coatings based on epoxy with antifouling features are used to integrate several functions into one material. This review discusses various types of epoxy-based antifouling coatings. The ability of nanomaterials, siloxanes, and conducting polymers to induce antifouling activity into the epoxy and corresponding antifouling mechanisms is also covered. The review concludes with the enormous potential of antifouling epoxy coatings as cost-effective, environmentally sustainable solution to biofouling in diverse industrial applications. Finally, the future ahead of antifouling epoxy coating is patterned.
