Challenge
In solar manufacturing, water is not just a utility; it is the lifeline that keeps production running and quality intact. The client needed a constant supply of 18.18 MΩ-cm ultrapure water (UPW) to ensure reliable production of high-performance solar cells. Simultaneously, the upcoming facility would generate complex effluent streams, including concentrated, dilute, and abatement streams, each with varying chemical characteristics, making treatment and reuse technically demanding.
The customer needed a robust effluent treatment plant (ETP) and recycled back into the UPW system. The client sought a single partner capable of engineering an end-to-end UPW and ETP with a zero liquid discharge (ZLD) solution, ensuring seamless integration, high recovery, and uncompromised manufacturing performance, while meeting environmental compliances.
Solution
Aquatech was chosen as the integrated water technology solution provider to offer ultrapure water (UPW), advanced effluent treatment, and Zero Liquid Discharge (ZLD) to ensure stable & high-performance solar operations meeting environmental compliance.
For UPW, Aquatech’s membrane subsidiary QUA’s FEDI®GIGA system was installed to consistently achieve 18.18 MΩ-cm resistivity, supporting precision manufacturing with stable and dependable performance. The effluent treatment plant incorporated Aquatech’s High Efficiency Reverse Osmosis™ (HERO) technology to enhance water recovery and improve resistance to fouling and scaling, supported by Q-SEP® ultrafiltration for effective handling of complex wastewater streams.
An advanced, energy-efficient ZLD system minimized scaling, reduced cleaning frequency, lowered steam consumption, and ensured long-term compliance. Aquatech delivered a complete turnkey solution, covering design, engineering, supply, erection, and commissioning.

Results
Project engineering, including P&IDs and detailed design, was completed on schedule, with supply clearance is on track to meet its commercial date. Once fully operational, the system will produce 85 m³/hr of ultrapure water, consistently meeting stringent quality parameters. The integrated ETP-ZLD solution will achieve 95-97% water recovery, significantly reducing freshwater consumption and eliminating liquid discharge. High recovery will lower reject volumes, enhance ZLD efficiency, reduce operating costs, improve energy performance, and ensure compliance with environmental regulations.
