Bottle washing machines: Filtration of caustic solution

Glass and PET bottles have been widely used in the beverage industry for many years. Breweries, mineral springs, producers of soft drinks or bottlers who employ deposit systems use bottle washing systems to clean glass or PET bottles.

Depending on the type of bottle washing system (one or two-ended version), the bottles are first immersed in one or more caustic baths. The inside of the bottles is then cleaned using spray nozzles.

Filtration of primary or secondary caustic solutions

Paper fibers, adhesives and varnishes cause most of the problems in caustic soda. To solve this problem, the BOLLFILTER Automatic Type 6.64 BWM or BOLL FineFilterUnit is used in the filtration of the secondary flow to continuously filter the caustic solution as conventional sedimentation is partially ineffective.
The aim is to remove impurifications from the caustic solution at an early stage to ensure that as little residue as possible reaches the subsequent caustic baths or post-treatment areas.

BOLLFILTER as particle filter and component protection

The BOLLFILTER Automatik aquaBoll®/ Type 6.18 BWM protects the components such as the heat exchanger against loss of performance and waste of resources. The particle filter also increases the cleaning quality of the bottles and prevents the spray bars from clogging.

Your benefits:

  • Increase in production times due to fewer machine stops
  • Significant improvement in the general machine condition
  • No deposits in flow-free areas
  • Minimal maintenance

BOLLFILTER membrane systems for reducing microparticles

The BOLL FineFilterUnit membrane system continuously separates all particles in the micrometer range (µm) due to its filtration capacity and thus supplies microparticle-free (filtrate) caustic soda.
The use of a BOLLFILTER membrane filtration system is an additional and advanced measure to reduce the contamination in the cleaned bottles.

Your benefits:

  • Increased service life of the caustic solution - reliable removal of impurifications
  • Significant reduction in overall impurification
  • The machine is in a better hygienic condition
  •  Reduction of microparticles / microplastics in the cleaned bottle
