The Challenge
The Solution
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.
The Benefits
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.
