  • Explore the capabilities of nanofiltration and ultrafiltration. Filters have similar looks, different applications

    Introduction Even if you’re an expert in reverse osmosis (RO) membrane technology, you may be overlooking some applications using often neglected cousins of RO: nanofiltration (NF) and ultrafiltration (UF). Although virtually identical in looks to RO membranes, NF and UF membranes serve distinctly different separation functions. Dramatic levels of resource recovery, efficiency ...

  • Working on a Love/Hate Relationship with the Surface Chemistry of Membrane Filters

    Water, oils, and solvents sometimes need to be filtered. But when you see filters labeled as hydrophilic, hydrophobic, and now oleophobic; what does all this mean?  Sterlitech currently offers membrane disc and sheet filters in 10 different polymer types and 4 inorganic filters. 2 of the polymer types are subdivided into 4 subgroups based on surface ...
