- •
MD and MCr were utilized for treatment of industrial wastewater containing high amounts of Na2SO4.
- •
Both untreated and nanofiltered solutions were concentrated via the MD/MCr processes.
- •
The untreated wastewater indicated the steadiest performance.
- •
No reduction in flux or wetting of the membrane surface was observed.
- •
Crystalline product of Na2SO4 was recovered as Thenardite.
- •
Crystals exhibit narrow size distribution and low incorporation of impurities.
