Nanofiltration with inorganic meso-porous membranes is being considered more and more for water purification applications. For specific applications inorganic membranes may have advantages over organic polymer-based membranes due to their rigid pore structure, and thermochemical stability. However, the permeability and, partly through that, the permselectivity of inorganic membranes need to be ...

The direct utilisation of side streams from membrane processing and evaporation is great potential interest for dairies to reduce water consumption. In an analytical screening 89 industrially obtained streams, samples varied in pH conductivity broad ranges 4.22 7.56 0.001 0.949 Siemens per meter, respectively. Detailed compositional data the enabled assessment their applicability as diafiltrati...

In this work, several machine learning techniques are presented for nanofiltration modeling. According to the results, specific errors are defined. The rejection due to Nanofiltration increases with pressure but decreases with increasing the concentration of chloride ion. Methods of machine learning represent the rejection of nanofiltration as a function of concentration, pH, pressure and also ...
