- Benefit from the positive synergies of different ingredients
- Increase cleaning power by combining
- Interactions can produce undesirable effects
With regard to the chemistry itself, due to the highly complex and always variable composition of the residues, there is no universal cleaning agent that would be capable of removing all types of residues. Most cleaners are used in the form of formulated mixtures. But if these are be successfully utilised, the following must be separately considered in the membrane maintenance:
The fact that no residues can be detected in the flushing water is no indication that the system and membrane are clean. Here there is a large and significant difference to CIP: even the smallest amounts of residues on or in the membrane alter their separation characteristics and thus their process technological advantages.
Successful membrane maintenance involves restoring the original condition of the membrane with regard to its separation characteristics. Over time, formulated cleaning agents can even damage the membranes, or make them more susceptible to contamination, since they have not been designed for the individual system concept and varying contamination profiles.
