Advancing Water Reuse and Salt Recovery with Total MLD Solution from DuPont
MLD Total Solution Drives Sustainable Water Reuse and Salt Recovery in China
Owned by Foshan Jialida Environmental Protection Technology Co., Ltd., this landmark 160,000 m³/d minimal liquid discharge plant treats complex textile dyeing and printing wastewater from approximately 200 industrial users. By combining DuPont™ IntegraTec™ ultrafiltration modules with DuPont™ FilmTec™ nanofiltration and reverse osmosis elements, the project helps reclaim water at high recovery while recovering sodium chloride brine and Glauber’s salt—setting a new benchmark for industrial water reuse and resource recovery.
