Bottled Water

Manufacturing bottled water requires the filtration of compressed air, liquid and steam. Donaldson’s full suite of process filtration technologies ensures that the final product meets global food safety standards.

We have extensive experience applying our compressed air filtration solutions to the bottle blowing process for some of the largest global bottled water manufacturers. Our high pressure compressed air solutions ensure the air used to blow open and shape the PET bottles is free of particulate, moisture, oil vapor, and bacteria.

Our liquid product portfolio is geared towards turning spring, well or municipal water into purified bottled water. Our liquid process housings offer sanitary designs that eliminate harbor points for bacteria and our LifeTec elements can do everything from protecting fragile RO membranes from particulate to removing micro-organisms from the final product.

Our steam filtration solutions are critical to following industry best practices and maintaining process integrity. By sterilizing the air and liquid elements that are capturing bacteria, the end user ensures the microorganism are not allowed to propagate and contaminate the final product. Our stainless steel housings and elements are designed to handle the harsh environment of steam systems and produce clean steam at various points of use.  

When Donaldson’s Process Filtration product portfolio is used in conjunction with industry best practices, we can effectively protect the brand and product integrity for bottled water manufacturers.

  • Bulk Water Filtration
    The removal of large contaminants from source water provides protection for the boiler and pre-filtration for finer filtration solutions.

  • Sterile Liquid Filtration
    The removal of micro-organisms prior to the packaging of bottled water.

  • Compressed Air Purification
    Bulk water and particulate removal from compressed air providing protection for pneumatic tools and equipment.

  • Sterile Air Filtration
    The removal of micro-organisms from compressed air used for bottle blowing.

  • Tank Venting
    The removal of micro-organisms from make-up air on product storage tanks.

  • Culinary Grade Steam
    The purification of steam used for sterilization of process equipment.

Filtration for Purity in Bottled Water Processing

With the European Directive EC/54/2009 the European Community has regulated the production and trading of bottled natural mineral waters and spring waters. Along with other guidelines (EC/83/98, EC/852/2004, etc.) Hazard Analysis and Critical Control Points (HACCP) plan or Hazard Analysis and Risk-based Preventive Controls (HARPC) plan to protect consumers against food-borne illness have become the focus of all production and processing means.

While facilities vary, in general, filtration as part of the preventive control is recommended at the following stages of bottled water processing:

  1. Incoming source water: Pre-filtration of well water to remove sediment, particulates and larger microorganisms through a 25 micron filter; produces factory water suitable for equipment and container cleaning.

  2. Intermediate processing: Depth filtration through a 5 micron filter to remove smaller particulates and impurities shed during resin or carbon activation steps to gain particulate-controlled water – usually used for dilution of CIP reagents.

  3. Fine filtration: Filtration through a 1 micron filter to remove colloidal contaminates like humic acids potentially present in the water or in containers.

  4. Final filtration: Critical filtering through a 0.2 micron filter just prior to packaging, using a highly efficent membrane filter to capture last remaining contaminants.

  5. In storage: Tank vent filters on stored product in holding tanks, to prevent the ingression of airborne contaminants while equalizing tank pressure as volume changes.

Working with an experienced filtration partner can help you design a system that is both compliant and cost-effective.
