Bottle washing machines: Filtration of caustic solution

Glass and PET bottles have been widely used for decades. Breweries, mineral springs, soft drink producers and bottlers who use deposit systems use bottle washing systems to clean glass or PET containers. By reusing the bottles several times and dispensing with disposable bottles, resources can be conserved, and a contribution made to environmental protection. 


Depending on the type of bottle washer (single or double-sided version), the bottles are first immersed in one or more caustic baths. The inside of the bottles is then cleaned using spray nozzles. The outside of the bottles is rinsed with rinsing devices. An efficient filtration solution in bottle washers is essential both for optimum durability of the caustic solutions and for the preparation of the CIP medium. Here we successfully rely on our tried and tested BOLLFILTERs.

Filtration of primary or secondary caustic solutions

BOLLFILTER filters and membrane systems remove paper fibers, adhesives, paints, fats, and proteins from the caustic solution. Experience has shown that these substances cause the greatest problems with inefficient caustic filtration in bottle washers. The BOLLFILTER Automatic type 6.64 BWM and the BOLL FineFilterUnit are used specifically in off-line filtration. Continuous caustic filtration effectively removes the dirt load introduced. This replaces conventional and sometimes ineffective sedimentation. 
The aim is to remove impurities from the caustic solution at an early stage. This is intended to minimize residues that could enter the subsequent lye baths or post-treatment areas through the bottle or the transport system. This is achieved by using the filtration solution within the bottle cleaning machine.

BOLLFILTER as particle filter and component protection

The BOLLFILTER automatic type 6.64 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.

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 via carry-over in the bottle washer by the bottle or the transport system.

Further protection for components and reduction of contaminats in the post treatment zones assures the BOLLFILTER type aquaBoll®, which can be installed for example in front of a regenerative energy heat exchanger or in front of spray nozzles for post caustic and water treatment zones. 

Advantages:

Increased production time

Increased production time

Fewer machine stopsdue to efficient filtration can minimize production downtime. The filtration solutions help to minimize deposits in the machines and thus promote smooth operation.

Improve overall machine condition

Improve overall machine condition

Our filtration technology prevents harmful particles from affecting the machine components of your bottle washers. Less contamination means less wear. This improves the general condition of the machines.

No deposits in flow-free areas

No deposits in flow-free areas

By keeping deposits away from the non-flow area, the service life of the caustic and the service life of the machine can be extended. This increases the efficiency and quality of life of your machines.

Low (maintenance) effort

Low (maintenance) effort

Thanks to the high quality of our filters and membrane systems, we offer the lowest possible maintenance effort. Thanks to our internal service teams, you have as little effort as possible in terms of commissioning, maintenance, and spare parts procurement.

Fully automatic operation

Fully automatic operation

The filtration process runs completely automatically. No machine operator is required for cleaning either, as our automatic filters and membrane systems are designed to be self-cleaning.

Minimal process interruption during implementation or conversion

Minimal process interruption during implementation or conversion

Thanks to the uncomplicated integration of BOLLFILTERs into existing processes, the duration of process interruption during implementation can be kept to a minimum.

BOLLFILTER membrane systems to reduce microparticles 

Thanks to its filtration performance, the BOLL FineFilterUnit membrane system continuously separates all particles in the micrometer range (µm) and beyond down to the nanometer range (nm). It therefore supplies the bottle cleaning liquor with a filtrate free of microparticles and turbidity. 

The use of a BOLLFILTER membrane filtration system is an additional and advanced measure for reducing the dirt load in the cleaning liquor by means of fine filtration. This efficiently reduces the carry-over of microparticles into the post-treatment zones of the bottle washer and has a positive effect on the results of industrial bottle cleaning. As a result, the BOLLFILTER membrane system helps companies to achieve consistent and increased product quality.

Additional advantages:

Increased service life of the caustic solution

Increased service life of the caustic solution

Continuous filtration ensures reliable removal of impurities. This leads to an improvement in lye quality and thus contributes to a longer shelf life. Operating costs can therefore be reduced.

Significant reduction in overall contamination

Significant reduction in overall contamination

Our filters and membrane systems reduce the carry-over of dirt particles and thus the overall contamination within the cleaning process. As a result, your PET and glass bottles can be cleaned more reliably. 

Reduction of the total microparticle load and carryover

Reduction of the total microparticle load and carryover

The precise filtration technology minimizes the carryover of microparticles into the downstream zones. Furthermore, the microparticle load in the pre-treatment zones is reduced by up to 80%. This allows you to improve and maintain your company's product quality after filling.

Increased cleaning quality and efficiency through overall dirt reduction

Increased cleaning quality and efficiency through overall dirt reduction

Thanks to the efficient removal of dirt particles from the caustic solution, the cleaning quality and cleaning efficiency are improved through the possible optimization of the bottle washer's cleaning parameters.

Higher production capacity due to increased production time (no sedimentation required)

Higher production capacity due to increased production time (no sedimentation required)

Eliminating sedimentation allows for more continuous production and without the frequent need for machine stops for cleaning or maintenance. By using our filtration technology, caustic loss is reduced by up to 45% compared to sedimentation. This increases production capacity/time. 

Reduced detergent and water consumption

Reduced detergent and water consumption

The effective BOLLFILTER filtration technology and the high degree of automation lead to a reduction in overall contamination in the main and secondary washing zones as well as in the water zones. This enables optimum use of fresh water and cleaning agents and leads to cost savings. We recommend the use of the BOLLFILTER cleaner, which has been adapted to the BOLLFILTER membrane systems and does not contain any additives.

Lower energy consumption

Lower energy consumption

The cooling of the caustic solution and the machine is reduced, resulting in lower energy costs.
