Ultraviolet purification is considered the most effective technology for protecting water against biological contamination. This makes it essential for food, beverage, medical, or other applications where absolute purity is required. Many UV systems used in these applications must meet stringent FDA requirements.
Pre-UV systems (upstream of RO systems) can be systems designed for disinfection or for chlorine & chloramine destruction. Post UV systems (downstream of RO system) can be designed for disinfection, TOC reduction, or when ozone is used, ozone destruction.
VARIABLES TO CONSIDER:
- Application requirements, including feed water characteristics, flow rates and point of use standards
- System configuration, including sizing, flange or sanitary piping connections, instrumentation and control options, electrical control cabinet electrical rating.
- UV Disinfection
- TOC (Total Oxidizable Carbon) Reduction
- Chlorine and Chloramine Destruction
- Ozone Destruction
- Food & Bev
- Life Sciences
- Medical and Dialysis
- Oil & Gas
- Power Generation
- Recreational Water
FREQUENTLY ASKED QUESTIONS (FAQ’s):
How do I know which unit I need? Systems are sized according to the application, and the ability of the fluid to transmit 254 nm UV light.
How often do I change the UV lamps? Lamps should be changed after 9000 hours of use, or in most cases about 1-year. UV lamps degrade with time — so even if they are lit, they may not be working effectively.
Does the UV system leave anything in the water? No, UV light leaves no residual traces in the water. It is a chemical-free and environmentally-friendly option.
