UV disinfection preserves the taste of Nu-Pure spring water

Nu-Pure Beverages is an Australian business that produces bottled spring water and other beverages. The company’s spring water is sourced from selected Australian springs, pure with a natural balance of minerals.

UV disinfection from UV-Guard Australia was selected by Nu-Pure process engineers to disinfect the spring water at a number of stages in the manufacturing processes. As UV disinfection is a chemical- and byproduct-free process, it can safeguard the water being produced without adversely affecting its taste and odour.

“The food and beverage industry is an increasingly regulated and safety-conscious market and must meet stringent quality standards. UV water disinfection can prolong shelf life without compromising on flavour, plus it delivers safe, uncontaminated and chemical-free products, making it ideal for goods for human consumption,” said UV-Guard Technical Director Luke Chamberlain.

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

“The systems we developed for Nu-Pure were both food-grade compliant and WaterMark certified. The UVG X3-440 is a multilamped system with three 450 W 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,” Chamberlain said.

“We also installed two UVG S440 units in parallel at both the Victorian and Queensland manufacturing plants. 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,” Chamberlain said.

“The UV-Guard equipment is an integral part of our quality management system and HACCP program to ensure a safe, quality product is continuously produced in our bottling plants,” said the national technical manager of Nu-Pure Beverages, Bruce Taylor.
