What to do if trans membrane pressure rises faster in Mitsubishi STERAPORE 5700?
- K
  Kara GallowayAug 17, 2025
  If the trans membrane pressure of your Mitsubishi Water Filtration System rises faster than usual, and chemical cleaning is needed more often, it could be due to several reasons: * The membrane flux might be too high: Adjust the permeate pump to an appropriate volume. * The membrane surface may be clogged: Adjust the air flow of the membrane scour blower to a proper value and perform membrane cleaning. * The MLSS might be too high: Adjust the discharge volume in the circulation pump to a proper value and increase the amount of excess sludge extraction. * The system may be clogged by inorganic matter: Perform acid cleaning.
