Vapor phase osmosis module useful in e.g. system to dry humid biomass, comprises double envelope of which internal envelope is constituted of polymer film and external envelope, which is impermeable to water that is in gaseous/liquid state

摘要

The vapor phase osmosis module comprises a double envelope of which an internal envelope is constituted of a polymer film, which is semi-permeable to water vapor and impermeable to water having a liquid state and an external envelope, which is impermeable to water that is in a gaseous state or a liquid state. An atmosphere between the envelopes is rapidly renewed by adding a blow of a gaseous fluid between walls of envelopes and by extracting the gaseous fluid from envelopes using an extractor. A surface of semi-permeable wall is corrugated that increases a surface of the semi-permeable film. Independent claims are included for: (1) a system for drying biomass by vapor phase osmosis; (2) a system for purifying waste water by vapor phase osmosis; (3) a system for desalinating water by vapor phase osmosis; (4) a process for drying biomass by vapor phase osmosis; (5) a process for depolluting the polluted water; and (6) a process for desalinating water by vapor phase osmosis.
