El desafío
Archroma is a global leader in dye manufacturing for the world’s leading apparel brands. Their manufacturing plant in Thailand produces wastewater with high levels of Total Dissolved Solids (TDS) and Chemical Oxygen Demand (COD). The primary challenge was identifying a solution to create a sustainable dye manufacturing process, maximize water reuse, and achieve ZLD. With limited cost-effective options for brine minimization, the client looked to partner with Gradiant to achieve its sustainability goals.
La solución
To treat a variety of feedwater quality and to achieve ZLD, Gradiant proposed a robust solution featuring 6 stages of RO Infinity with CFRO and FRO. The CFRO system demonstrated it could concentrate brine recoveries up to 95%. The wastewater was then treated by FRO to remove color by oxidizing the organics. This solution also proved successful to remove high TDS and COD, allowing for the dye wastewater to be reused in the manufacturing process, while saving up to 40% CAPEX compared to Ultra-High Pressure RO (UHPRO).
Beneficios
Gradiant delivered a custom RO Infinity with CFRO system that achieves ZLD, as well as beneficial reuse of the wastewater. The process produces fresh water that contains 24 to 48 times less TDS, and can be reused for dye manufacturing. The FRO technology achieves a colorless brine concentrate stream that can be processed as a by-product for salt preparation and resin regeneration. Gradiant’s RO Infinity is used for the primary solution to reduce fouling and scaling.
