Аннотация
The paper presents the results of an experimental study on the effect of high pressures on the transport of liquids through a composite reverse osmosis membrane of an AG-90 industrial membrane module (GE Water & Process Technologies), which membrane consists of a microporous substrate (polysulfone) coated with a selective polyamide layer. It has been found that when a "philic" liquid (water) is forced through the membrane, permeability changes nonlinearly with increasing pressure and passes through an extremum at 7.5 MPa. For the membrane from the AG-90 module, hysteresis during the pressure increasing-decreasing cycle has been observed, which can be associated with irreversible deformation of the membrane structure by interaction with water at high pressures. For "phobic" liquids (glycerol, propanol-1, and propanol-2), the membrane permeability decreases nonlinearly with increasing pressure and this change can be explained in terms of known transport models.
