Food & Beverage Water Disinfection

Water quality is important to food & beverage plants. A dairy, food factory or beverage plant has many uses of water. For example, to wash fruit or vegetables, to mix beverages, to wash containers & equipment, etc. Any microorganisms in the water can contaminate the products.

Therefore, food & beverage plants pay special attention to microbial quality of their water.

Food & beverage water disinfection with UV has many advantages:

  • Reliable disinfection: No microorganism is known to resist adequate UV dose.
  • No change to taste or smell: With UV there is no change to taste or smell of water.
  • Corrosion free: There is no risk of pitting corrosion of stainless steel pipelines, because UV doesn’t affect pH of water.
  • Online monitoring: UV intensity monitors provide real time control of the disinfection process.
  • Inexpensive: Total cost of UV disinfection works out to a few cents per m3.

UV Sizing for food & beverage applications

Australian Drinking Water Guidelines recommend minimum 40mJ/cm2 UV dose at the end of lamp life for potable water disinfection. It is easy to provide a higher UV dose at a very small incremental cost. Consequently, many manufacturers prefer a higher UV dose to provide a safety margin.
