Mineral Waters

The optical brightness of a bottled mineral water is possibly the first measure of quality made by many consumers. The clarity of a bottled mineral water can be influenced by a number of factors, including quality of the water source, airborne bacterial contamination from storage vessel vents and carbonating systems.

Water source filtration

Our filters can provide clarity, bioburden reduction and sterility. Suitable filter cartridges include Klearfil™ and Polyfil™ II depth filters, and the Biofil™ PES membrane filter.

Cryptosporidium filtration

Our Cryptofil™ filter is a fully validated filter for the removal of Cryptosporidium oocysts from water.

Final filtration

The removal of spoilage organisms such as yeast and bacteria is assured with the use of our integrity testable membrane filter, the Biofil™ PES.

Gas filtration

Our Fluorofil™ and Fluorofil™ Plus filters can ensure the removal of spoilage organisms from CO₂, N₂ and air, and can also be used for sterile venting and blanket transfer.

Tanker transfer

Porvair filters can provide the assurance of quality during transfer from tank to tank, or tank to process. Suitable filters include Klearfil™, Polyfil™ II or Biofil™ PES depending on the requirements.

Bottle rinsing filtration
