APPLICTION –

Natural spring water treatment

PROJECT BACKGROUND

Nu-Pure Beverages are a 100% Australian owned business who produce bottled spring water and other beverages. Their spring water is sourced from specially selected pristine Australian springs, pure with a natural balance of minerals.

Nu-Pure pride themselves on producing a natural product and sustainability is an important factor in everything they do. The spring water they use must be free from bacteria and other pathogens. The taste and odour of the product must also not be detrimentally impacted by any water treatment processes used.

UV disinfection was selected by the Nu-Pure process engineers as a safe, reliable and cost effective method to disinfect the spring water at a number of stages in their manufacturing processes. As UV disinfection is a chemical and bi-product free process, it was the ideal solution to safeguard the water being produced without adversely affecting its taste and odour.

Nu-Pure contacted UV-Guard with requirements for UV disinfection units at three stages of their manufacturing processes, two stages in their Victoria manufacturing plant and one stage at their Queensland manufacturing plant.

UV REQUIREMNTS

  • WaterMark certified UV reactors – Food grade compliant
  • UV dose of 40 mJ/cm²
  • UV Transmittance (%UVT) of 96%

UVG X3-440UVG X3-440

The UVG X3-440 is a WaterMark certified multi-lamped system with three 450W UV lamps designed for food grade applications where a large treatment flow is required. The unit is installed with a UV intensity monitor to alert Nu-Pure whenever the design UV dose is in risk of not being achieved. This could be as a result of water quality deterioration, quartz tube fouling or lamp failure.

The a UVG S440 system is also WaterMark certified. Two units were installed in parallel at both the VIC and QLD manufacturing plants. The UVG S440 systems were also installed with UV intensity monitors. Installing two units in parallel allows for a level of redundancy. If one unit is out of action for servicing, disinfected water can still be achieved though the other system.
