6T/H Two-Stage RO + EDI + Nuclear-Grade Resin Ultrapure Water System for Lithium-Ion Battery Industry

Customer Background

Our client, a leading lithium-ion battery manufacturer based in Malaysia, required a high-performance ultrapure water system to support its electrode coating and cell assembly processes. The project demanded consistent water quality of 18.2 MΩ·cm with strict control of TOC and silica levels to ensure battery performance and longevity.

Solution Provided

We designed and supplied a 6T/H Two-Stage Reverse Osmosis (RO) + EDI + Nuclear-Grade Mixed Bed Resin ultrapure water system.
Key system features include:

• Two-Stage RO for efficient desalination and reduction of conductivity load.
• EDI (Electrodeionization) for continuous, chemical-free deionization.
• Nuclear-Grade Resin Polishing Unit to achieve ultrapure water quality up to 18.2 MΩ·cm.
• Fully Automatic PLC Control System with real-time monitoring and data logging.
• 304 Stainless Steel Piping and UPVC for pretreatment, ensuring durability and hygiene.

Project Highlights

• Capacity: 6 tons per hour (continuous operation)
• Feed Water: Municipal tap water
• Final Water Quality: Resistivity ≥ 18.2 MΩ·cm, TOC < 10 ppb
• Installation Site: Malaysia
• Delivery Time: 45 days from order to commissioning

Outcome

The system was successfully commissioned and integrated into the production line. The customer reported stable operation, low maintenance, and excellent water quality, meeting all process requirements.
This project strengthened our partnership and set a benchmark for high-end ultrapure water solutions in Malaysia’s rapidly growing battery industry.
