Water Treatment Membrane

LOTTE Chemical selected water treatment technology as a next-generation growth engine and started to develop technologies. We have acquired world-class water treatment membrane technology through continuous development of wastewater treatment and water reuse. LOTTE Chemical strives to become a global chemical company that thinks of improving the value of life and harmony with the environment.

UF Membrane for water treatment
It offers clean and safe water through optimized systems and process engineering technologies for various water treatment sectors such as purified water, reused water, sewage/waste water MBR (Membrane Bioreactor) process, etc.

Hollow Fiber Membrane
The proprietary hollow fiber membrane developed by LOTTE Chemical is a separate reinforcing material that achieves excellent strength and low weight at the same time. Moreover, excellent chemical resistance and stain resistance of PVDF (Polyvinylidene fluoride) material enable long-term stable use (or operation). LOTTE Chemical reduced energy waste by optimizing the air flow path of the module and cassette and saved maintenance cost by developing aerator that optimizes aeration efficiency.
High-performance hollow fiber membrane
- Production of excellent quality treated water with 0.03 micrometer (㎛) nominal pore diameter
- Pollution resistance acquired by using PVDF material, which has high chemical resistance
- Produced in cutting-edge facilities to ensure excellent and uniform quality hollow fiber membrane
