Enabling India's clean energy future with chemical-free ultrapure water
A leading solar manufacturing facility in India required a reliable, high-capacity ultrapure water solution to support large-scale production while reducing environmental impact and operational complexity.
Using Xylem's Ionpure® CEDI technology, the customer achieved chemical-free ultrapure water production, reduced system footprint, and improved overall operational efficiency.
The challenge
As solar manufacturing scales across India, ultrapure water quality becomes increasingly critical to maintaining product consistency and operational reliability.
The customer needed a solution that could:
- Support high-volume UPW production
- Eliminate regeneration chemicals
- Reduce plant footprint
- Simplify operations and maintenance
- Support long-term sustainability objectives
- Conventional resin-based systems required acid and caustic regeneration, increasing chemical handling, wastewater generation, and operating complexity.
The solution
Xylem delivered an Ionpure® Continuous Electrodeionization (CEDI) system designed to provide:
- Continuous chemical-free operation
- Consistent ultrapure water quality
- Compact modular design
- Lower maintenance requirements
- Reliable high-flow performance
The solution was engineered to support a 110 m³/hr ultrapure water application, helping the customer meet both production and sustainability goals.
The results
- 110 m³/hr - High-capacity ultrapure water production
- >50% - Reduction in footprint compared to conventional systems
- Zero - Regeneration chemicals required
- Improved Sustainability - Reduced wastewater generation and chemical handling requirements
Why it matters
The project demonstrated that chemical-free ultrapure water production can successfully support large-scale solar manufacturing applications.
By combining reliability, sustainability, and operational simplicity, Ionpure® CEDI helps manufacturers reduce environmental impact without compromising performance.
