“…Various prevention and treatment methods are being studied to attempt to mitigate biofouling, including chemical treatments (i.e., linoleic acid (plant fatty acid) [ 27 ]; nitric oxide [ 28 ]; urea [ 29 ]), membrane modifications (i.e., silver nanoparticles [ 30 , 31 , 32 , 33 ]; triclosan [ 34 ]; carbon nanotubes [ 35 ]; Arabic gum [ 36 , 37 ]; hydrophilic membranes [ 38 ]; capsaicin [ 39 ]), and biological treatments (i.e., bacteriophages [ 40 ]; quorum-quenching [ 41 , 42 ]). Before these methods can be employed, the treatment methods must be rigorously tested to determine anti-biofouling efficacy, impacts on the membranes, and safety for humans and the environment.…”

As potable water scarcity increases across the globe; it is imperative to identify energy and cost-effective processes for producing drinking-water from non-traditional sources. One established method is desalination of brackish and seawater via reverse osmosis (RO). However, the buildup of microorganisms at the water-membrane interface, known as biofouling, clogs RO membranes over time, increasing energy requirements and cost. To investigate biofouling mitigation methods, studies tend to focus on single-species biofilms; choice of organism is crucial to producing useful results. To determine a best-practice organism for studying antimicrobial treatment of biofilms, with specific interest in biofouling of RO membranes, we answered the following two questions, each via its own semi-systematic review: 1. Which organisms are commonly used to test antimicrobial efficacy against biofilms on RO membranes? 2. Which organisms are commonly identified via genetic analysis in biofilms on RO membranes? We then critically review the results of two semi-systematic reviews to identify pioneer organisms from the listed species. We focus on pioneer organisms because they initiate biofilm formation, therefore, inhibiting these organisms specifically may limit biofilm formation in the first place. Based on the analysis of the results, we recommend utilizing Pseudomonas aeruginosa for future single-species studies focused on biofilm treatment including, but not limited to, biofouling of RO membranes.

“…Currently, many anti-biofouling membranes have been prepared via surface modication. 7,[11][12][13][14][15][16] The methods of surface modication include physical coating or deposition, layer by layer self-assembly, free radical initiated polymerization and so on. Among those methods, the second interfacial polymerization (SIP) which utilizes the unreacted active groups on the membrane surface is not only more stable than physical methods but also easier and more effective than most of chemical binding methods.…”

“…Among those methods, the second interfacial polymerization (SIP) which utilizes the unreacted active groups on the membrane surface is not only more stable than physical methods but also easier and more effective than most of chemical binding methods. 7,14,15,17 The anti-biofouling strategies usually focus on improving the anti-adhesive and/or antimicrobial properties of membranes. The surface properties (such as hydrophilicity, roughness, charge) are supposed as essential factors to control membrane biofouling.…”

“…Many biocides which involve metallic nanoparticles (such as Ag, Cu, ZnO NPs), antibiotics, quaternary ammonium salts, carbon-based materials (carbon nanotubes, graphene oxide) and N-halamines have also been incorporated onto the membrane surface to kill the bacteria effectively and reduce the rate of biolm formation. 12,14,[24][25][26][27] Nevertheless, the bactericidal surface may make microorganisms attach and colonize on the membrane surface more easily due to the rapid accumulation of dead microbial cells. 28 Hence, it is more efficient to fabricate anti-biofouling membranes with both anti-adhesive and anti-microbial features.…”

“…[46][47][48][49][50] Moreover, COS is rich in amine groups, which could be easily functionalized and immobilized onto the nascent RO membrane surface. 14,29,51,52 In this paper, to simultaneously improve the water ux and anti-biofouling performance of RO membrane, we prepared a biguanidine functional chitooligosaccharide (COSG) and graed the COSG on the nascent RO membrane by second interfacial polymerization. The biguanide groups of COSG could increase the cationic density and improve the anti-bacterial performance of COS signicantly.…”

The superhydrophilic modification of the aromatic polyamide (APA) thin‐film composite (TFC) membrane surface was achieved by densely grafting quaternary ammonium cations (QACs) and salicylaldehyde units with polyethylene glycol (PEG) chains as the spacers. The experimental results showed that the superhydrophilicity of the modified membrane surfaces was due to the abundant hydrophilic groups, such as PEG chains and QACs. The water fluxes of the modified membranes significantly increased by 36–39% compared with the hydrolyzed membrane, and the salt rejections slightly decreased. The accelerating chlorination tests showed that the modified membranes had the durable chemical stability in 7 × 105 ppm/hr chlorine aqueous solution at room temperature. Gram‐negative bacteria Escherichia coli and gram‐positive bacteria Staphyloccus aureus adhering to and growing on the modified membrane surface had been effectively prevented due to a combination of obstructing bacterial adhesion and contact‐killing during the incubation.
