Normalizing is REQUIRED to properly analyze. When you startup with new membranes, note the Primary Pressure, Pressure Drop (Perm to Conc) and Permeate Conductivity. Track them and look to clean at 10% increase in any of the three. Look to replace as the cleanings get less effective and time between cleanings decreases.
Also, look for changes that could indicate other problems. For example, a decrease in Primary Pressure and Pressure Drop with an increase in Permeate Conductivity could indicate membranes damaged by chlorine oxidation,
