Our Membrane compressed air dryers pass the compressed air through a membrane with pores large enough to allow air molecules through but not large enough to allow water molecules through.  A purge flow of dry compressed air is passed over the membrane to pick up the collected water and carry it out of the dryer.  The lower a dew point is needed, the more purge air is required.  These dryers are limited in sizes and are usually installed on small, point of use applications.
