Web(Figure 2). The rate of clean water flux through the membrane is measured as liters per membrane area per hour (L/m2-h). Water flux divided by the transmembrane pressure is the normalized water permeability or NWP (L/m2-h-bar). The NWP values are compared to initial (pre-process) levels and may be analyzed for trends over time. WebUnder constant flux operation, TMP increases to compensate for the fouling. On the other hand, under constant pressure operation, flux declines due to membrane fouling. In some technologies such as membrane distillation , fouling reduces membrane rejection, and thus permeate quality (e.g. as measured by electrical conductivity) is a primary ...

WebMay 26, 2005 · The current system design is for constant flux. This makes it easier to sell a X gpm system because the flow rate is constant and prevents some problems on the front end (like larger EQ). I have the feeling that constant TMP would make the system run at a more steady state. WebMembrane fouling is often characterized using a crossflow filtration apparatus. Typically, the transmembrane pressure (TMP) difference is fixed, and the flux is allowed to decline as the membrane fouls and the resistance to mass transfer increases.
