Process for recovering dyes and clean water from textile industry wastewater using membrane contactors
ES2984965
A process based on emerging membrane technologies, using membrane contactors, to recover dyes and clean water from textile industry wastewater, which has a very high environmental impact. The process involves a pretreatment with ultrafiltration to remove unwanted solids, followed by the concentration of dyes through membrane contactors, applying membrane distillation or osmotic membrane distillation. The result is the production of clean water and concentrated dyes, ready for reuse in dyeing new garments. The invention provides an innovative solution to address the treatment of textile industry effluents, promoting water reuse and dye recovery in an efficient and sustainable manner.
ADVANTAGES - High efficiency by reducing pigments, and improving output quality. - Water consumption reduction with this technology. - Cost-Effectiveness: Lowers production and operational costs while maintaining high reliability and effectiveness. BUSINESS APPL. Industrial sectors with high water treatment to remove contaminants, like textile or food industries.
