... of the world, the shortage of good quality feed-water is forcing plant owners either to run their membrane systems with undesirable levels of silica or to restrict recovery rates. High silica brines can cause severe and irreversible membrane fouling. Restricting recovery rates is never a popula ...

... (NF), and the interaction between membrane and pollutant in water cleaning-up were studied. The separation efficiency of pollutants like silica, nitrate, manganese and humic acids (HA) by means of RO and NF membranes (both of spiral wound type, in polyamide) was determined. The interactio ...

... pervaporation setup. Inorganic membranes were synthesized via a two-step sol–gel catalysed process employing tetraethylorthosilicate as the silica precursor. In addition, non-ligand surfactants were embedded and carbonized into the silica matrix. Normal silica membranes have typica ...

... and proton conductivity as sulfuric acid doping agent concentration was increased. The KSiN is unique in term of its miscible hybrid structure of silica particles modified with Nafion® structured Krytox 157 FSL chain (KSi) and Nafion®. Based on the KSiN membranes with different KSi content, it wa ...
