Nano Technology

OZ-SEPA’s
Core Technology

As part of the development of water pollution control technology, the OZ-SEPA membrane succeeded in developing an oil-water separation membrane through nano-scale surface treatment and completed patent acquisition.

The membrane of the nanostructure is an innovative technology that drains water and prevents 99% of oil from passing through, and the separated oil can be recycled without physical change.

Core Technology 1


Innovative technology to filter 99% of oil from water using nanostructure


99% oil recovery from water using direct filtration rather than absorption.

 Principles of a Nanofilter

  • In Nano-surface treatment the cellulose based material’s surface is covered with nanostructures.
  • These nanostructures have a high aspect ratio (around 10-50 nm) and are specifically tailored to be highly hydrophilic (water loving) but also highly oleophobic (oil hating).

STEP 3

Processing after processing

Oil being completely rejected by the processed filter surface

 Principles of nanostructures

  • As seen in the photo to the left, water will adhere to these structures, forming a membrane that blocks oil from passing. Since water is more dense than oil it will pass through the pores, leaving only oil behind.
Core Technology 2


The world’s first oil filter which uses direct filtering rather than absorbent methods.


99% oil recovery from water using direct filtration rather than absorption.

Key Features of Our Nano Membrane Technology

  • Maintains pollution levels below 3ppm,
    making water immediately drinkable after oil-water separation
    (Korea Polymer Testing & Research Institute).
  • 99% separation and recovery of spilled oil through simple filtration.
    • Capable of recovering all types of oil, 

      from low-viscosity silicone oil to crude oil.
    • Dramatically reduces severe secondary environmental
      pollution caused by conventional oil spill response methods.
    • Provides the disaster prevention market with low-cost,
      high-efficiency environmental protection materials.
