Logistics-Center Fluoride Issue — RO System
3-stage pretreatment + RO resolved fluoride, hardness and particulates in one system.
A reverse-osmosis (RO) system was designed, fabricated and installed for a logistics center in Icheon, Gyeonggi. The source water exceeded the drinking-water standard for fluoride and also carried high particulate and hardness loads.
Diagnosis
- Fluoride — above the drinking-water limit
- Particulates — heavy
- Hardness — high
Solution — 3-stage pretreatment + RO
Pretreatment was built in three stages — sediment, activated carbon and ion-exchange softening — followed by an RO unit custom-designed to the site and target quality.

Installation & commissioning
Media/resin charging, electrical interlock between the main panel and pretreatment valves, level-switch integration and fail-safe drain piping; staged commissioning from pretreatment backwash through manual and automatic RO modes.

Result
Multiple quality factors resolved in one system, delivered turnkey from design to commissioning.
