There are two major symptoms that we typically associate with membrane damage: 1. Increase in permeate conductivity coupled without a loss in productivity, or in extreme cases, with an increased productivity– this could indicate delamination or chemical damage. Membrane probing can determine whether this increase permeate conductivity is simply due to leakage at the permeate
