UltraViolet Irradiation (UV) is primarily employed as a disinfection process.
Inactivates waterborne pathogens without using chemicals, UV light changes the DNA and protein structure of viruses and bacteria and stops them from reproducing.
The Advantages include:
- Effective for all types of microorganisms
- Low capital, operating and maintenance costs
- Compact and easy to install
- Efficacy is independent of pH
- No impact to the aesthetic water quality
- Safe and environmentally-friendly
An Envirogen Group Water UV system was recently installed at a soft drinks production factory, as a final sterilisation process. Upstream of the UV, town’s water is treated with a chlorine sterilant, to a prescribed residual with contact time. To prevent water or final product tainting, a PureFlow Carbon adsorption process removes free residual chlorine. Post UV, final filters offer cryptosporidium protection before supply to product make up. A PureFlow Reverse Osmosis system treats the product make up water, to supply low mineral content water for isotonic beverage production, with a point of use UV steriliser on the treated water storage tank outlet.
