“…A lot of other factors could also affect this process, and these factors could be classified into microbial properties (Camesano and Logan, 1998;B. Tang et al, 2016), membrane surface characteristics (Nguyen et al, 2016), and surface-bacteria interactions (Kang et al, 2004;Walker et al, 2004), as well as operational conditions (Habimana et al, 2014). In brief, as illustrated by Fig.…”

Reverse osmosis (RO) membrane technology is one of the most important technologies for water treatment. However, membrane fouling is an inevitable issue. Membrane fouling leads to higher operating pressure, flux decline, frequent chemical cleaning and shorter membrane life. This paper reviews membrane fouling types and fouling control strategies, with a focus on the latest developments. The fundamentals of fouling are discussed in detail, including biofouling, organic fouling, inorganic fouling and colloidal fouling. Furthermore, fouling mitigation technologies are also discussed comprehensively. Pretreatment is widely used in practice to reduce the burden for the following RO operation while real time monitoring of RO has the advantage and potential of providing support for effective and efficient cleaning. Surface modification could slow down membrane fouling by changing surface properties such as surface smoothness and hydrophilicity, while novel membrane materials and synthesis processes build a promising future for the next generation of RO membranes with big advancements in fouling resistance. Especially in this review paper, statistical analysis is conducted where appropriate to reveal the research interests in RO fouling and control.Graphic Abstract

“…The bottle was tightly closed with the bottle cap before shaken at 150 rpm for 2 h at a temperature of 28°C in the incubator. The rapid duration of incubation was selected mainly to analyse the initial bacterial adhesion and to inhibit the biofilm formation [46]. According to Renfro et al [39], less than 2% of rhamnolipids are biodegraded within 4 h of incubation time, which indicates that the growth of bacteria can be neglected.…”

Bacterial adhesion on surfaces is an essential initial step in promoting bacterial mobilization for soil bioremediation process. Modification of the cell surface is required to improve the adhesion of bacteria. The modification of physicochemical properties by rhamnolipid to Pseudomonas putida KT2442, Rhodococcus erythropolis 3586 and Aspergillus brasiliensis ATCC 16404 strains was analysed using contact angle measurements. The surface energy and total free energy of adhesion were calculated to predict the adhesion of both bacteria strains on the A. brasiliensis surface. The study of bacterial adhesion was carried out to evaluate experimental value with the theoretical results. Bacteria and fungi physicochemical properties were modified significantly when treated with rhamnolipid. The adhesion rate of P. putida improved by 16% with the addition of rhamnolipid (below 1 CMC), while the increase of rhamnolipid concentration beyond 1 CMC did not further enhance the bacterial adhesion. The addition of rhamnolipid did not affect the adhesion of R. erythropolis. A good relationship has been obtained in which water contact angle and surface energy of fungal surfaces are the major factors contributing to the bacterial adhesion. The adhesion is mainly driven by acid-base interaction. This finding provides insight to the role of physicochemical properties in controlling the bacterial adhesion on the fungal surface to enhance bacteria transport in soil bioremediation.

“…Além das características dos suportes, o mecanismo da imobilização varia com os tipos de microrganismos, concentração de nutrientes, atividade metabólica e outras características físicas dos meios. Portanto, os fatores que afetam a adesão podem ser químicos, físicos e biológicos (NOMURA et al, 2008;BASILE et al, 2010;NGUYEN et al, 2016). (WU et al, 2006;BASILE et al, 2010;FIA et al, 2010;LIN et al, 2011;CHU;SHEN, 2012;WATANABE et al, 2013).…”

“…Ahammad et al (2013) observaram que organismos metanogênicos carregados negativamente (-24 mV) aderiram mais a suportes carregados negativamente (-24 e -25 mV) que a suportes carregados positivamente (+48 e +55 mV). Nguyen et al (2016) relataram que a hidrofobicidade, a baixa energia de superficial e as forças de van der Waals teriam papeis mais importantes na adesão de células aos suportes que o potencial zeta, pois essas forças são capazes de isolar as superfícies de contato, promovendo maior adesão. De fato, a hidrofobicidade tem sido descrita como uma das propriedades mais importantes envolvidas no processo de adesão de biomassa (FAILLE et al, 2002;NOMURA et al 2008;MURI et al, 2018).…”

“…As diferenças entre as atividades das biomassas aderidas são causadas, principalmente, por dois fatores. O primeiro relacionado com a adesão seletiva de diferentes espécies de microrganismos a cada suporte (NOMURA et al, 2008;OLIVEIRA et al, 2009;NGUYEN et al, 2016;LIU et al, 2017). Isso induz a rotas metabólicas distintas em cada biofilme e, consequentemente, diferentes capacidades de transformar o substrato (WEIB et al, 2013).…”
