In South Korea, reliable ultrapure water (UPW) production is critical for industries such as electronics and pharmaceuticals, where even trace contaminants can compromise product quality and system performance.
At this site, brackish lake water served as the primary feed source. While abundant, lake water often contains suspended solids, organics, and dissolved metals, particularly iron, that pose significant risks for downstream membrane processes.
Iron fouling was identified as the main challenge, leading to frequent cleaning, reduced efficiency, and shortened lifespans of reverse osmosis (RO) and electro deionization (EDI) units.
To address this issue, the facility sought a more robust pretreatment solution capable of consistently removing suspended iron and safeguarding sensitive downstream systems.
Project Overview:
In this project, we treated effectively 500 m³/day of brackish lake water to produce UPW for their cooling processes.
Problem: Iron fouls downstream RO and EDI units, reducing efficiency, increasing cleaning frequency, and shortening membrane lifespan.
Solution: Installation of a new UF system to effectively eliminate suspended iron particles and safeguard the RO and EDI units
Treatment Capacity: 500 m³/day
- Membrane: EUF
- Filtration process: Pretreatment Cartridge Filter-UF-BWRO-EDI
- Location: South Korea
Outcome: Consistent UPW Quality. Iron was completely removed at the UF stage, ensuring ultrapure water that meets strict industrial standards.
Key insights from this case study:
UPW Reliability Depends on Pretreatment
- Brackish lake water with suspended solids and dissolved iron posed serious fouling risks to RO and EDI units.
- Pretreatment quality directly determined the stability of the downstream ultrapure water system.
Process Integration Strengthens Performance
- The full chain: Cartridge Filter → UF → Brackish Water RO → EDI. Ensured high-purity water production.
- Each stage contributed, but UF was the turning point for stable long-term operation
Industrial Impact
The integration of a proper UF system in the feed line allowed the efficient treatment of 500 m3/day, improving the process, and the plant now produces consistent ultrapure water for cooling purposes.
