OZ SEPA Inc.

OZ SEPA Inc., headquartered in Seoul, South Korea, develops and manufactures nano-structured membrane systems for direct oil-water separation under the OZ-Sepa brand name. The company's foundational technology is a patented membrane featuring hydrophilic and oleophobic nanostructures in the 10 to 50 nanometer range that achieves 99 percent oil rejection and produces effluent below 3 ppm in a single filtration pass, eliminating the need for secondary or tertiary treatment. The OZ-Sepa membrane achieves what the company describes as the world's first nano-structured oil separation membrane that breaks the limits of conventional separation methods. The product portfolio scales from handheld tools to industrial stationary systems: Nano Membrane filter media serves as the core filtration substrate, Oil Skimmers come in five configurations from Windmill type through S-4, S, M, and L sizes for progressively larger recovery operations, Oil Boom provides containment with integrated membrane separation, Oil Scooper and Oil Ladle offer manual recovery options for localized applications, and the stationary Oil Separator handles continuous or batch processing. The membrane recovers all oil types from low-viscosity silicone oil through crude oil, with recovered oil recyclable without physical change. OZ SEPA's technology has received Korea Coast Guard validation demonstrating 900 times greater efficiency than conventional absorbent pads, positioning it for marine oil spill response, ship wastewater treatment, aquaculture water quality management, and industrial oil-water separation in food processing, refining, manufacturing, and functional textile applications.
