  • Advantages of Pressure MF Systems Over Vacuum Systems | WWD

    Range of PressureImproved CleaningMore ReliabilityLower CostsFinal AnalysisPressure systems operate within a greater range of operating pressure, resulting in some advantages over vacuum systems. A limitation of vacuum systems is that they can operate only within the range of atmospheric pressure, typically operating at pressures approaching 70% of the maximum pressure differential available (10-11 psid). Pressure systems, on the other hand, rely on a greater reserve of pressure should upset conditions occur in the system, operating at 40 to 50% of the maximum transmembrane pressure (16-20 psig) when tested on the same waters. This builds an intrinsic safety factor into a design that allows the pressure system to better cope with process upset, changes in influent water quality or any other changes in plant operation. Pressure systems are also immune to the impact of temperature changes that affect vacuum systems. During winter, for example, feed water temperatures drop, which increases viscosity and the pressure required to force water through a membrane...

  • What is a Micron? - HVAC School

    Jul 25, 2018 · In the micron vacuum scale, we start at 760,000 microns at sea level atmospheric pressure and work down towards a perfect vacuum of 0 microns or 0 hg. This is why a lower # in the micron vacuum scale equals a better / deeper vacuum, a higher number equals a worse / less deep vacuum.
