500TPD Ultrapure Water (UPW) System for a Leading Electronics Manufacturer

Introduction

In the electronics and semiconductor industry, water quality is not just a utility—it’s a critical component of product yield and reliability. Recently, Globaluf Water Treatment Co., Ltd. successfully delivered a high-precision 500M³/D Ultrapure Water (UPW) System for a prominent electronics factory in Jiangxi. This system is engineered to meet the most stringent international standards, consistently delivering water with a resistivity of over 18 MΩ.cm.

Challenge

The client required a stable, large-scale water supply for high-end electronic component rinsing. The source water needed extensive purification to remove suspended solids, dissolved ions, and organic carbon to nearly undetectable levels.

Globaluf Solution: UF + Double Pass RO + EDI

Our engineering team designed a multi-stage membrane-based solution to ensure total reliability and water purity.

Explore the core components of our high-performance solution below

1. Pre-treatment: Ultrafiltration (UF) System To protect the downstream membranes, we utilized a 750TPD UF System. This stage effectively removes colloids, bacteria, and macromolecules, ensuring a low Silt Density Index (SDI) for the RO feed water.

2. Core Desalination: Double Pass Reverse Osmosis (RO) The heart of the system is our 500TPD Double Pass RO System. By passing the water through two successive RO stages, we achieve a salt rejection rate of >99.5%, providing the high-quality permeate required for the EDI polishing stage.

3. Final Polishing: Electrodeionization (EDI) For the final “polishing” stage, we integrated an EDI System. This continuous process removes remaining ions without the need for chemical regeneration, maintaining a stable output of 18.2 MΩ.cm ultrapure water.

Result

The system is now fully operational, helping our client in Jiangxi achieve superior production quality. With over 20 years of experience and ISO9001 certification, Globaluf continues to provide cost-effective, high-performance water solutions to over 100 countries.
