The resulting membranes, with molecular weight cut-offs in the ultrafiltration (UF) or nanofiltration (NF) range, demonstrate an increase in water flux compared to commercial polymeric NF membranes, while achieving comparable rejection of dissolved organic carbon, nutrients, and PFAS. The MoS₂ layer forms a new selective barrier that enhances performance in rejecting charged species, while remaining chemically stable in acidic, basic, and solvent-rich environments.

Unlike polymeric membranes, which typically need replacing every 2 years, Molymem’s ceramic membranes deliver operational lifetimes of 10+ years. This durability significantly reduces the frequency and cost of replacements, lowering operating expenditure (OPEX) over the long term. Combined with their superior chemical stability and higher flux performance, Molymem membranes offer utilities and industries a more sustainable, reliable, and cost-effective solution for advanced water treatment.
