文摘
- •
The effect of vacuum application in DCMD (V-DCMD) was studied.
- •
Low partial pressure and non-condensable gas removal enhanced V-DCMD flux by 30%.
- •
V-DCMD mass transport model was represented by dimensionless coefficient (α).
- •
Simulated empirical fouling predictions correlated with the experimental data.
- •
V-DCMD for wastewater ROC treatment was found suitable on a lab scale study.
