Abstract This paper focuses on modifying a PES membrane with acid-functionalised carbon nanotubes (CNT) for industrial wastewater treatment. Embedding acid functionalised (CNTs) within the matrix would increase flux by increasing pore size and surface area, rejection thermal stability. Pure membranes were prepared phase inversion method infused CNTs at 2.5, 5, 7.5 10 wt% loading to fabricate PES/2.5 CNT, PES/5 PES/7.5 CNT PES/10 respectively. Characterisation was performed using Transmission...

Acid mine drainage is an environmental problem associated with mining operations and activities. Its treatment essential to achieving sustainability. In this study, a polyethersulphone (PES) membrane infused chitosan proposed as point-of-use material for treating acid (AMD). The composite explored the synergetic effect between polymer, particularly considering of degree deacetylation (DD) on performance membrane. Chitosan was produced from chitin under various synthesis process conditions...

Abstract In this article, performance evaluation of PES membrane infused with chitosan and coated polyamide layer for treatment acid mine drainage (AMD) is reported. PES/chitosan membranes were fabricated by varying concentration (0, 0.5, 0.75 1 wt%) using phase inversion method. (PA) via co-solvent assisted interfacial polymerization technique (CAIP). Scanning electron microscopy (SEM) contact angle analysis show that could enhance permeability without affecting rejection the membrane. The...

Acid mine drainage (AMD) is an environmental issue linked with mining activities, causing the release of toxic water from areas. Polyethersulphone (PES) membranes are explored for AMD treatment, but their limited hydrophilicity hinders performance. Chitosan enhances hydrophilicity, addressing this issue. However, effectiveness depends on chitosan's degree deacetylation (DD), determined during process chitosan production. This study optimized chitin temperature, alkaline (NaOH) concentration,...

In this study, chitosan was synthesised from chitin and used to modify polyethersulphone (PES) membrane prepared by the phase inversion method. PES blended with various concentrations of produce PES/0.5 wt% chitosan, PES/0.75 PES/1 membranes.

Polyethersulfone (PES) is commonly used to fabricate ultrafiltration (UF) membranes applied during the treatment of wastewater due its high permeability and tensile properties, chemical thermal stability. However, PES has low hydrophilicity sulfonyl functional group therefore becomes susceptible fouling, resulting in reduced membrane performance lifespan. In this study, 10 wt% PES/CNT were prepared by infusing 2.5, 5, 7.5 Carbon nanotubes (CNTs) into produce PES/2.5 CNT, PES/5 PES/7.5 CNT...

The work demonstrates the performance of polyamide membrane in removal manganese ions from single salt aqueous solution simulating real acid mine drainage. was tested using a dead-end filtration cell with sulphate used to prepare feed solution. flux and metal rejection evaluated. Effect operating parameters such as pH, initial concentration pressure on investigated. varied between 10 15 bar it observed that increasing increases flux. Acidic pH conditions contributed contaminate Mn2+ are...

The #FeesMustFall movement, which rocked institutions of higher learning in South Africa 2015/2016, inspired robust engagement around the decolonization knowledge. Students argued that epistemological context education does not reflect African context. Activists if curricula did speak to local issues, challenges facing would remain. Incorporating indigenous knowledge practices into mainstream could signify a shift away from Western dominance episteme. Engineering is immune decolonization....

Acid mine drainage (AMD) is an environmental issue linked with mining activities and operations, it the flow of toxic, polluted water from areas. Polyethersulphone (PES) membranes have been studied as a potential eminent solution to AMD treatment. However, PES are less hydrophilic in nature, thus poor membrane performance. Chitosan has identified hydrophilicity-enhancing agent that can address this limitation. Nevertheless, enhancement offered by chitosan depends on its degree deacetylation...
