Membrane cleaning has changed both quantitatively and qualitatively in the past 40 years but there are basic steps that should be followed. Cleaning time, temperature, hydrodynamic conditions, and concentration of cleaning agents all affect membrane-cleaning efficiency, Cleaning membranes can be costly and ineffective cleaning more so. Most membr...

A review of real-world membrane facility (UF/RO) operating data, highlighting the importance of implementing a normalization program. Raw operating data will be compared to normalized data illustrating the impact of parameters like feed temperature or conductivity. Data normalization enables daily variations in operating conditions to be accounted ...

Membrane fouling is typically multifaceted meaning cleanings can often leave non-targeted foulants behind. Matching the appropriate chemical to remove the corresponding foulant on the membrane surface is the greatest hurdle in achieving an effective cleaning. A variety of techniques exist to help identify what is fouling the system and by extension...
