Water Treatment Membrane

In 2011, 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.

Application

  • Water treatment for drinking water production

  • Wastewater treatment and discharging

  • Reuse of scarce water resources

  • Production of deionized water for electronic and pharmaceutical fields

  • Seawater desalination for industrial and drinking water production

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

Module

High-efficiency module

- Optimized airflow through module header thickness optimization

- Energy-saving products that maximize energy efficiency by smooth air flow

Cassette

Low-energy, high integrated cassette

- Minimized operating pressure loss through an optimized flow design

- Improved membrane integration by efficient layout of cassette components

Aerators with optimized aeration efficiency

- Reduced maintenance cost by generating large air bubbles with small air volume and maximizing cleaning effect

- Uniform aeration effect within cassette even with a low air flow rate

- Effective physical cleaning and stable operation even in high integration of membrane modules

System

Optimal process system configuration

- Efficient and stable membrane process operation through proven operation sequence and control logic

- Operational convenience through automated backwashing and washing system
