Exomembranes provides epoxy‑based ultrafiltration and nanofiltration membranes that retain performance across the full pH range (0‑14), strong oxidants, and solvent‑rich environments. The positively charged, chemically robust membranes can be tuned from loose UF to tight NF, enabling industrial water‑treatment engineers to handle harsh, high‑fouling streams with lower cleaning costs and reduced downtime.

Problem
Conventional ultrafiltration and nanofiltration membranes degrade when exposed to extreme pH, oxidizing chemicals, high temperatures, or aggressive solvents, leading to frequent replacement, high cleaning costs, and limited applicability for harsh industrial waste streams.
Solution
Exomembranes offers epoxy-based UF and NF membranes that maintain structural integrity and performance across the full pH range (0‑14), under strong oxidants, and in solvent‑rich environments. The membranes’ positive surface charge enables selective removal of positively charged contaminants without excessive pressure or intensive cleaning cycles. By leveraging the tunable chemistry of epoxides, the product line can be customized from loose ultrafiltration to tight nanofiltration to meet specific separation challenges. The technology is supplied as ready‑to‑install modules that can be integrated into existing water‑treatment plants, allowing industries such as dairy, metallurgy, and chemical processing to treat high‑fouling or extreme‑pH streams with reduced downtime and lower operational costs.
Target Audience
Primary customers are industrial water‑treatment engineers and process managers in sectors such as dairy processing, metallurgical waste treatment, and chemical manufacturing that require reliable separation of harsh or high‑fouling streams.
