What is it about?
Water scarcity and environmental concerns are driving innovation in treating difficult water sources, such as seawater and oilfield-produced water. This study investigates the performance of two types of membrane distillation (MD) systems—Air-Gap Membrane Distillation (AGMD) and Vacuum Membrane Distillation (VMD)—when used to purify saline feeds and produced water.

Why is it important?
Produced water from oil and gas operations is often difficult to treat and reuse. This study compares two MD technologies to provide critical insight into which system is more suitable for field applications. The results support the use of membrane distillation as a sustainable solution for water reuse in arid, oil-producing regions.
Perspectives
- Both AGMD and VMD achieved high salt rejection, but VMD showed higher water flux under vacuum conditions. - AGMD was more energy-efficient at lower temperatures. - The study identifies the trade-offs between energy use and performance in MD systems, guiding future technology selection.
