RO Membrane Surface Factors Influencing Specific Flux
Reverse osmosis (RO) membranes used to treat municipal wastewater for reuse become fouled with inorganic, organic and biological materials present in the feedwater, causing a decrease in RO efficiency. The feedwater matrix varies continuously throughout the RO feed channel; in a 3-stage RO system, the feedwater solute concentration increases over 6...
Removal of Colloidal Particles through Online Monitoring to Lower Microfiltration Membrane Fouling
Fouling of microfiltration (MF) membranes results in increased energy demand, increased cleaning intervals, and membrane replacement frequency. MF membrane fouling is largely due to deposition of colloidal nanoparticles...
