Two-stage RO + EDI ultrapure water system; direct drinking water systems for office, production, and dormitory buildings. Produced water is used for manufacturing ultrapure water (resistivity > 18.2 MΩ·cm) and drinking water.
Project Background
Zhuhai Bojie Electronics Co., Ltd. is a high-tech enterprise specializing in the R&D and manufacturing of automated test equipment, based in Zhuhai, Guangdong Province. Its products are widely used in consumer electronics and automotive electronics sectors, where production processes require strict water purity standards.
Project Challenges
Bojie Electronics' production lines require ultrapure water for cleaning precision electronic components and preparing solutions for testing equipment, with a required product water resistivity of >18.2 MΩ. Additionally, safe and convenient direct drinking water must be provided to employees in the office building, production facility, and dormitory. The project requires strategically routing piping across the three buildings to ensure stable water pressure at all usage points and compliance with water quality standards.
Solutions
Baiyuan Water Industry designed a comprehensive water treatment solution for Bojie Electronics. The ultrapure water system uses a "2-stage RO + EDI" process, maintaining stable resistivity above 18.2 MΩ to meet precision manufacturing requirements. The drinking water system employs centralized production with a recirculation network: stainless steel piping connects three buildings, with drinking terminals installed on each floor to ensure fresh water quality and optimal temperature.
Use Device
Ultra-pure Water System: Multi-media filter, activated carbon filter, water softener, single-stage RO unit, double-stage RO unit, EDI module, terminal mixed-bed polisher, and online water quality monitor. Drinking Water System: Commercial RO water purification unit, stainless steel circulation piping, smart drinking terminals on each floor, and scheduled circulation disinfection device. Production capacity: 1 T/H ultra-pure water plus ample supply of potable water.
Outcomes & Benefits
- Ultra-pure water resistivity remains stable at >18.2 MΩ, ensuring high-quality cleaning of precision electronic components.
- The potable water system serves three buildings and benefits all employees.
- Loop piping design ensures fresh water quality and prevents stagnant water from harboring bacteria.
- Fully automated system with easy maintenance and low operational costs
- Enhanced enterprise production environments and employee satisfaction
