도전 과제

One of India’s largest companies sought Gradiant to support a new solar photovoltaic (PV) cell and module manufacturing. In recent years, solar renewable energy has grown from a niche market of small-scale applications to a mainstream electricity source. This site has been integral to a national goal of sourcing 45% of India’s power from non-fossil fuel sources. The production of solar cells generates complex wastewater from rinse acid and alkaline process streams, as well as burnbox effluent. These streams contain high levels of ammonia, fluoride, silica, ammonia, and TDS, which necessitates complex yet optimized solutions to ensure adequate treatment for reuse. They also required fluoride concentrations to fall below two ppm to comply with Minimum and Zero Liquid Discharge (MLD, ZLD) requirements.

솔루션

Gradiant is delivering a high recovery RO Infinity (ROI) system, and pretreatment and ultrafiltration (UF) to the client for an industrial wastewater and recycling solution. The integrated facility will treat the complicated wastewater streams from solar PV manufacturing to allow for recycling and reuse in their upstream processes, helping our client minimize their water footprint and meet sustainability goals.


Gradiant created two flowsheets for the process and burnbox effluent streams, combining selective contaminant extraction (SCE) and RO Inifinty (ROI) technologies for both ammonia and fluoride removal, as well as treating water that is reused on-site. Gradiant is also providing chemicals and O&M services to ensure consistent and reliable operations.

혜택

By taking a value engineering approach early in the project, the Gradiant team was able to fast-track a viable solution for the customer. The client recognized this was a significant feat given the complex waste streams and a compressed project timeframe, which could only have been achieved through simplifying startup, commissioning, and ongoing operations for the client as part of an integrated solution.


The ROI system will recover up to 85% of the wastewater for on-site use and achieve ZLD limits. The future-proofed design will also increase plant capacity as the customer innovates new products and creates additional waste streams.
