RO Membranes with HPA Technology

Permionics RO (Reverse Osmosis) membranes are reinforced with cutting-edge HPA (High Performing Architecture) Technology, that not only improves membrane performance and output quality but also enhances long-term durability amounting to substantial cost-savings and minimizes environmental impact.

Flat Sheet Membranes

We offer the MF/UF/NF/RO membranes with various molecular weight cut-offs (MWCO) and different polymer chemistries. Flat sheet membranes are made with a variety of materials including Polyvinylidene fluoride (PVDF), Modified Polyether sulfone (PES), Unmodified Polyether Sulfone (PES), Polysulfone (PS), Polyamide (PA).

They offer extensive benefits including high thermal and chemical resistance, precise MWCO, high flux capacity, fouling resistance, acid and caustic resistance, high temperature resistance etc.

Spiral Membranes

Sanitary-type membranes for pharmaceutical, biotech, food processing, glass-fiber, and general industrial applications.

We manufacture spiral-wound membranes with a wide variety of materials and MWCO. All our membranes have a compact design and an optimum ratio of surface area to volume. The height of the feed channel can be varied by the thickness of the feed-spacer material (28 to 120 mil).

This helps adapt the viscosity or the solid content of the liquid. The design features provide excellent hydrodynamics in combination with low energy demand. Membrane modules for specialty applications for acidic/caustic solvent resistance or high temperature are available.
