Spring water bottling plant UV treatment

Applications: Food & Beverage


Nu-Pure Beverages, QLD and VIC


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 Requirements

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

UV Guard’s Solution

Stage Peak flow rate Solution
VIC – Pre storage tank between pre filtration processes 60m3 UVG X3-440
VIC – Post storage tank treatment prior to silver and final filtration 2 x 20m3 2 x UVG S440
QLD – Post storage tank treatment prior to silver and final filtration 2 x 20m3 2 x UVG S440

UVG 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.


2 x UVG S440 systems in parallel

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.

  • Combatting High Chlorine for Swim School Health & Safety

    UV Guard installed a tailored solution for improving water quality at a popular NSW swim school, bringing chlorine levels down to meet NSW Health requirements and ensuring a safer and more enjoyable environment for all.

  • Stopping the spread of viruses in aquaculture research facility

    The aquaculture facility had multiple research stations all independently researching different fish species at the same time, and each one of these stations required its own UV system to treat the water entering that specific area. Additionally, all seawater entering the research facility needed to be treated. All UV systems needed to be selected to achieve minimum UV doses to achieve sufficient inactivation of viruses such as white spot.

  • Proof low pressure UV treatment is an effective approach for public swimming pools

    A 25m public swimming pool was struggling to implement consistent reductions in chloramine (combined chlorine) levels – especially during peak swimming periods. In addition, enrolments at their learn to swim classes had failed to increase for the past 2 years due to parental concerns about allergic reactions to chloramines such as trichloramines.

  • Underwater World – UV disinfection for sea water aquarium

    Underwater World in central Mooloolaba, located in the heart of Queensland’s famous Sunshine Coast is renowned for being the area’s top family attraction. The aquarium is home to a range of marine life including fish, sea animals and corals. The marine life must be protected from a range of diseases including bacteria, fungi, viruses and protozoa.
