    The presence of human factors in escape and evacuation on offshore installations has been studied by many researchers and engineers. The studies lack of analysis on human factors in the design of emergency equipment to increase chances of success during emergencies. This paper presents the survey on basic offshore safety and emergency training for individuals working on platforms in tropical water. The main objective of the research is to identify human factors issues faced by individuals performing escape and evacuation on offshore platforms in tropical water. A set of questionnaires was distributed to 16 individuals participating in the Tropical Basic Offshore Safety Induction and Emergency Training (T-BOSIET) at Terengganu Safety Training Centre, Kemaman

    Nowadays, anaerobic membrane bioreactors (AnMBRs) are one of the considerable wastewater treatment technologies. However, the performance of AnMBRs in wastewater treatment is faded due to the membrane fouling issue. Due to that concern, it gives a reason to find a material with high quality properties to prepare an antifouling membrane for the application in AnMBRs. In this present study, a new ultrafiltration (UF) membrane incorporated covalent organic framework (COF) was successfully constructed by interfacial polymerization method. A mixed-matrix membranes (MMMs) in various concentrations of COF range of 0 to 1 wt% was prepared and characterized by SEM, XRD, FTIR and AFM analysis. The analysis has confirmed the incorporation of the COF to the UF membrane. The effect of various COF concentration towards the antifouling property of the prepared membranes were evaluated. The results show, the increasing of COF concentration from 0 to 1 wt% has led to the increasing in the rejection rate from 26.11% to 95.87%. Besides, the membrane hydrophilicity significantly improved by 30.53%, when the water contact angle decreased from 66.94° to 46.50°. These results suggested that the PES/COF MMMs has great potential to offer an efficient separation with superior antifouling membrane for AnMBRs

    A covalent organic framework (COF) was successfully incorporated to construct a new ultrafiltration (UF) membrane via interfacial polymerization. A mixed-matrix UF membranes with concentrations COF range of 0 to 1 wt% have been prepared and characterized. The influence of COF concentration on the membrane morphology and antifouling property has been evaluated. Increasing COF concentration from 0 to 1 wt% could significantly enhance the rejection rate from 26.11% to 95.87% for bovine serum albumin (BSA). Moreover, membrane hydrophilicity significantly improved by 30.53%, with the decrease of water contact angle from 66.94° to 46.50°

    Textile wastewater contains high level of chemical oxygen demand (COD) and color concentration, and the release of this effluent can adversely affect ecosystem and water quality. Conventional ultrafiltration (UF) membrane incapable to treat small size pollutants (such as dyes and multivalent ions) from the wastewater. Previously, we had successfully fabricated tannin-modified metal–organic frameworks (Tannin-MIL), then incorporated it in the polyethersulfone (PES) polymer matrix. The modified membrane has more hydrophilic surface than unmodified PES surface, making it more resistant and less prone to be affected by fouling. Herein, this study aimed to explore the performance of ultrafiltration mixed matrix membrane for textile wastewater treatment. The novel Tannin-MIL/PES membrane possessed excellent rejection up to ∼ 100% total suspended solid (TSS), 96.46% (COD), 97.04% (color), 97.41% (turbidity) and 89.94% total dissolved solid (TDS), with permeability up to ∼ 190 L/m2.h.bar during filtration of textile wastewater, which is 9.31 times higher compared to the unmodified PES membrane

    The application of ferric-metal-organic framework for dye removal: A mini review

    Dye effluent released from the industries is one of the most severe environmental concerns due to their potential adverse effects on human health. There are many obstacles encountered in degrading dye materials as they are not only very stable to light and heat but also resistant to biodegradation and oxidation reactions. Currently, porous metal-organic frameworks (MOFs), an important class of advanced functional materials due to its novel coordination structures and diverse topologies, have shown potential applications in various fields, including dye removal. Among the highly water stable MOFs, Ferric-based MOFs like iron (III) trimesate, which is also known as MIL-100(Fe), is favorably ascribed by its simple synthesizing method as well as its wide availability. Herein, this paper summarized the recent progress achieved by MIL-100(Fe) in removing different types of dye, together with its sustainable preparation method
