Influence of the characteristics of soluble algal organic matter released from Microcystis aeruginosa on the fouling of a ceramic microfiltration membrane

Effect of feedwater pre-treatment using UV/H 2 O 2 for mitigating the fouling of a ceramic MF membrane caused by soluble algal organic matter

“…AOM has been demonstrated to cause severe fouling for low-pressure polymeric [5][6][7][8] and ceramic membranes [9,10] as it contains a high proportion of high molecular weight (MW) biopolymers such as polysaccharides and proteinaceous substances which have been identified as the most problematic foulants for the membranes. Moreover, the blooms can lead to the release of harmful algal metabolites including toxins into the drinking water, posing a threat to human health [11].…”

Caracterização Morfológica E Parâmetros Funcionais De Membrana Cerâmica Multitubular

“…A maioria das membranas comerciais são produzidas por alumina, sílica, zircônio, titânio ou uma combinação destes óxidos (Lorente-Ayza et al, 2015). Os materiais TiO2 e ZrO2 conferem a membrana características hidrofílica, proporcionando redução na formação de incrustações, resistência química em soluções ácidas e básicas (Zhang et al, 2013;Vinoth Kumar et al, 2015). No espectro obtido percebe-se que a membrana possui principalmente em sua estrutura TiO2, não Todos as informações e direitos sobre o presente artigo são de total e única responsabilidade do(s) autor(es).…”

Advanced characterization of dissolved organic matter released by bloom-forming marine algae

“…Furthermore, dissolved AOM is usually not retained by pretreatment and can initiate and/ or exacerbate particulate/organic fouling and biofouling in downstream RO membranes [16]. A number of studies have shown a correlation between the polysaccharide fraction of AOM and MF/UF membrane fouling [17][18][19][20]. Since AOM from different algae have different fouling potential and mechanisms [21,22], it is important to analyze the structure and composition of algal PS released by different species for a better understanding of the interaction of these compounds with membrane surfaces.…”
