Long-term effects of anti-biofouling proton exchange membrane using silver nanoparticles and polydopamine on the performance of microbial electrolysis cells

Prevention and removal of membrane and separator biofouling in bioelectrochemical systems: a comprehensive review

“…In addition, the reduced contact angle of the membrane with the nAg-pDA composite layer had reduced internal resistance, resulting in a 12% improvement in power density. A dual role against the adhesion of microorganisms to the membrane surface was also indicated by Park et al (Park et al (2020).…”

Bio-electrochemical frameworks governing microbial fuel cell performance: technical bottlenecks and proposed solutions

“… 133 While adding silver nanoparticles to polydopamine prevented PEM fouling due to its antimicrobial nature. 134 Affordable PEM is also considered a bottleneck, a low cost activated carbon derived from coconut shell and blended with natural clay enhanced PEM hydration property and proton transfer which led to an increase in the coulombic efficiency of the MFC. 135 In another report, ceramic membrane modified with rice husk ash exhibited high proton transfer and low oxygen diffusion, 136 while sulfonated biochar-PVA composite showed an increase in the proton conductivity (32 fold) compared to Nafion membranes.…”

Influence of Nanomaterials and Other Factors on Biohydrogen Production Rates in Microbial Electrolysis Cells—A Review

“…Three-dimensional (3D) metal nanoparticles have been used to improve the efficiency of PEM as bio-fouling agents for the fabrication of membranes with high anti-fouling resistance. In a study by Park et al (2021) using silver (Ag) nanoparticles to modify PEM to reduce the harmful effecting of biofouling on Bio-HPR, the PEM was coated with antibacterial Ag nanoparticles [ 70 ].…”

“…Another method was used for membrane coating, which was an Ag nanoparticle coating, followed by coating with a polydopamine layer. The results of running the MEC using membranes that were coated with Ag nanoparticles and polydopamine in these two ways showed a high efficiency of bio-hydrogen production by 68.12% and reduction in biofouling to 80.74% compared to using the original membranes [ 30 , 70 ].…”
