Problem Addressed

Membrane distillation (MD) is used to separate the more volatile components of a mixture via phase change. MD is well-suited for harnessing solar and geothermal energy sources and is often used in off-grid desalination applications. Meanwhile, the overall market is dominated by large-scale, multi-stage distillation systems that produce millions of gallons of desalinated water per day with low energy consumption. The inventors have developed a permeate gap (PGMD) system that shows promise for higher efficiencies as these large-scale systems with lower capital investments.
