Pollution of the caustic soda solution of bottle washing machines caused by fibres and micro-particles


New plants carry over essentially less caustic soda solution. The use of fresh water is reduced to a minimum. As a result of the use of synthetic glue the lye depose much less and so fibres as well as particles stay in the lye. This can lead to the following problems:

  • Blockage of spraying nozzles is being generated and prohibits a correct wash-out
  • High time and cleaning effort to remove mud from the main lye and pipes
  • Problems of waste disposal concerning the caustic mud
  • Intensified generation of deposits in the water zones (limestone-fibres materials)
  • Microparticles trigger secondary gushing, which reduces the filling performance when bottling. Even when opening the bottles, problems can occur due to overfoaming.



With the equipment filter TC® SCREEN TS Tensid-Chemie GmbH has developed a system which can remove fibres of labels and particles effectively.

This concept provides the following advantages:

  • A very easy and robust structure
  • Cheaper than systems with complex membrane technology
  • Space-saving due to low weight easy to install
  • Very low follow-up costs as it is nearly maintenance free
  • Effective removal of fibres and particles and as a consequence “cleaner” bottles
  • Improved quality of the caustic soda solution
  • Use even without a settling tank because of the reduction of intervals of sedimentation
  • No reduction of additives or deformers from the lye
  • No disposal costs of the caustic sludge due to a continually label removal
  • Clean and low-particle water zones
  • A minimum of water- and electricity consumption
  • Fast return of investment due to reduced cleaning time and elimination of sludge disposal


(“Only unintentional, technically unpreventable residues of a compound may still be in the end product if they are harmless for the health or if they don’t affect technologically the end product.”)
