It is very important to regularly monitor the operation of your membrane plant to be sure that problems are not creeping in. Typically, membrane issues will gradually happen over a long period of time (days, weeks or even months). However, changes to the plant operating conditions (especially temperature and feed salinity) may disguise problems or make it look like you have a problem when you don’t. Normalisation of data can overcome these problems
Therefore, data normalisation is necessary before comparing system operating data from one day to the next.
Software for normalisation is available from most RO membrane manufacturers, for example Hydranautics RODataXL or Dow Filmtec FTNorm.
Gensep provides data monitoring and normalisation services, and we can provide advice and guidance if any operational changes are needed.
