Overview
Meat, cereal, chips... Regardless of how simple or complex a food manufacturing process is, every process owner needs to identify two crucial points for filtration:
- Points where contamination is first generated or introduced, and
- Critical control points where contamination of the product or process is at high risk, or where there is a "last chance" to remove it.
Plants that use multiple ingredients, heat and air treatments and packaging steps may require a more complex filtration system, but the common challenges remain. Consider filtration as the last possible processing step to remove surviving contamination and prevent the pickup of harmful bacteria just prior to packaging.
Through Donaldson's leading expertise we know that safe and cost-effective liquid, steam and air filtration is all about filter staging: the right efficiency at the right micron size in the right location.

Applications
- Filtration up to Process Water
- Process Water
Process water can indirectly come in contact with the final product, such as water used for rinsing bottles or rinsing after chemical disinfectants.
- Ingredient Water
Ingredient water comes in direct contact with the final product, such as water that becomes part of the final product. This water can be filtered down to sterile grade using Donaldson PES membrane elements.
- CIP Solutions
Clean in Place (CIP) solutions can be monitored for pH, filtered, and re-used in many applications rather than treating and sending the water to drain.
- Packaging and Filling
Filtration of final products (e.g., beer, wine, olive oil or bottled water) or aqueous solutions can be done using Donaldson's liquid filtration.
- Cooking or Culinary Steam
Culinary grade steam is essential to maintain integrity of a product and associated equipment. Steam can be used for cooking or direct injected into a product. Filtration saves money because:- Filtered steam is a quality assurance measure that protects against product recalls.
- Filtered steam protects against unexpected downtime imposed by safety inspectors, regulators, or audits.
- Compressed Process Air and Gases for Processing and Storage
