Abstract: This study explores the potential of membrane distillation (MD) technology as a
one-step process for treating and reusing dye textile wastewater. The research
synthesizes MD membranes using a novel H2O/Isoamyl alcohol non-solvent in
phase inversion with varying ratios to enhance hydrophobicity, thermal stability,
and evaluate water flux and dye removal efficiency. Results showed that the
optimal MD membrane, with a 50:50 H2O/Isoamyl alcohol ratio, achieved high
water flux (18.05 L/m2 h) and color removal efficiency (99.69%), along with a
water recovery of 60.35% after 16 hours of operation. Additionally, the
synthesized MD membrane demonstrated approximately 1,3 times higher water
flux than the commercial MD membrane due to its greater porosity. The results
demonstrated that isoamyl alcohol can improve the long-term performance of
MD membranes, offering a sustainable solution for dye recovery and wastewater
treatment in the textile industry by utilizing waste heat from dyeing wastewater.
Overall, the synthesized MD membrane shows promise as an effective solution
to address dye wastewater treatment challenges in Bao Loc's textile sector.2025-08-01T00:00:00ZInnovative Gamma-irradiated membrane for enhanced performance in membrane distillation treatment of real textile-dyNguyễn, Thị HậuHung Cong DuongNguyễn, Công NguyênTuan Hung PhamSong Toan Pham PhuDoan Van Hong ThienDuong Thi ThanhMinh-Hiep NguyenXuan-Cuong Lehttps://scholar.dlu.edu.vn/handle/123456789/60542026-01-07T02:56:56Z2025-12-01T00:00:00ZTitle: Innovative Gamma-irradiated membrane for enhanced performance in membrane distillation treatment of real textile-dy

Abstract: For the first time, a novel method to enhance the water flux and wetting resistance of polyvinylidene fluoride
(PVDF)-based membrane distillation (MD) membranes by subjecting the polymer solution to gamma irradiation
prior to phase inversion (i.e. denoted as deep gamma-irradiated PVDF-MD membrane) was implemented in this
study. Compared to conventionally prepared PVDF-MD membrane (i.e. phase-inversion without gammairradiation), the deep gamma-irradiated PVDF-MD membrane exhibited larger but more evenly distributed
pore sizes and higher porosity (i.e. 84 ± 1.9 % vs 76 ± 1.2 %), resulting in a 1.8-fold increase in water flux. The
enhanced membrane pore structure and water flux of the deep gamma-irradiated PVDF-MD membrane were
attributed to the facilitated cross-linking between polymers induced by high-energy gamma-irradiation. More
over, the fourier transform infrared spectroscopy data indicate that the deep gamma-irradiated PVDF-MD
membrane exhibited a higher β/α phase ratio compared to the non-irradiated membrane. When tested with a real
textile wastewater, the deep gamma-irradiated PVDF-MD membrane achieved water flux of 38.7 L/m2.h and
colour removal of >99.5 % at feed and distillate temperatures of 70 ◦C and 20 ◦C, respectively. Moreover, this
enhanced PVDF-MD membrane helped concentrate dye in the wastewater by a factor of 2.5, from an initial
colour concentration of 1536 PtCo to 3882 PtCo, after 12 h of operation without any evidence of membrane pore
wetting. The results reported here draw important practical implications for realisation of MD to boost circularity
in textile dyeing facilities.2025-12-01T00:00:00Z
