During the production of oil and gas, a large amount oily wastewater is generated, which would pollute environment if discharged without proper treatment. As one most promising treatment options, membrane material used for should possess desirable properties high hydraulic performance combined with fouling resistance. This project employs vapor induced phase separation (VIPS) technique to develop hydrophilic polyvinylidene fluoride (PVDF) polyethylene glycol (PEG) as an additive produced...
Water is a quintessential element for the survival of mankind. Its variety uses means that it always in constant state demand. The supply water most primarily comes from large reservoirs such as lakes, streams, and ocean itself. As such, good practice to monitor its quality ensure fit human consumption. Current monitoring often carried out traditional labs but time consuming prone inaccuracies. Therefore, this paper aims investigate feasibility implementing an Arduino-based sensor system...
A strategy that can be used to develop metal–organic frameworks (MOFs) capture per- and poly-fluoroalkyl substances (PFAS) from water is functionalizing them with fluorine moieties. We investigated different fluorine-functionalization strategies their performance in removing PFAS using molecular simulations. Perfluorooctanoic acid (PFOA), one of the most widely encountered sources, was as probe molecule. Our simulations show functionalization by incorporating fluorinated anions bridging...
A large amount of wastewater is directly discharged into water bodies without treatment, causing surface contamination. rotating biological contactor (RBC) an attached treatment process that offers a low energy footprint. However, its unstable removal efficiency makes it less popular. This study optimized operating parameters in RBC combined with external membrane filtration (RBC-ME), which the latter acted as post-treatment step to stabilize performance. Response methodology (RSM) was...
This paper reports the application of silica derived from natural biomasses rice husk and bagasse ashes as membrane modifying agents. The modification was conducted on poly(ether sulfone) (PES) by blending into dope solution. aimed to improve structure hydraulic performance resulting PES membrane. effects addition system were evaluated through analysis change in chemical using ATR-FTIR, surface morphological AFM, hydrophilicity water contact angle measurement. SEM AFM images show loading...
Wastewater containing oil/water emulsion has a serious ecological impact and threatens human health. The worsens as its volume increases. Oil/water needs to be treated before it is discharged or reused again for processing. A membrane-based process considered attractive in effectively treating emulsion, but progress been dampened by the membrane fouling issue. objective of this study develop polyvinylidene fluoride (PVDF) membranes customized separation incorporating assembly tannic acid...
Membrane-based technology is an attractive option for the treatment of oily wastewater because its high oil removal efficiency, small footprint and operational simplicity. However, filtration performance highly restricted by membrane fouling, especially when treating oil/water emulsion as a result strong interaction between droplets hydrophobic property membrane. This study explores fabrication polyvinylidene fluoride (PVDF)-based via vapour induced phase separation (VIPS) method while...
Membrane fouling deteriorates membrane filtration performances. Hence, mitigating is the key factor in sustaining process, particularly when treating fouling-prone feed, such as oil/water emulsions. The use of spacers has been expanded module system, including for control. This study proposed a rotating spacer system to ameliorate issues an emulsion. system's effectiveness was assessed by investigating effect speed and membrane-to-disk gap on hydraulic performance energy input through...

Abstract This study illustrated the changes, pollution status, and significant causes for Brunei River, Darussalam. Eleven parameters (pH, temperature, oxidation–reduction potential (ORP), dissolved oxygen, biochemical oxygen demand, conductivity, total solids (TDS), salinity, turbidity, ammonia-nitrogen (NH3-N), coliform) were analyzed from eight monitoring sites in 1984, 2019, 2020, 2021. Box plots used a comparative between 1984 2019+ data, while hierarchical cluster analysis (HCA)...
Coliform bacteria pollution poses a significant challenge to water quality in the Brunei River, critical resource Darussalam. This study investigates impact of seasonal variations and population growth on coliform concentrations across eight monitoring stations while addressing data limitations forecasting future trends. Seasonal variations, analyzed using box plots, revealed significantly higher levels during rainy season, driven by urban residential runoff. Population growth, assessed...
