THIS DOCUMENT GENERALLY DESCRIBES THE PROPERTIES OF UV SYSTEMS
IN ORDER TO KEEP YOU AND THE EQUIPMENT SAFE, READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION OR OPERATION.
UV water system is a popular, highly effective, and easy to use way to protect your water from living organisms. UV systems are used in homes, offices, and many commercial and industrial applications.
What is UV Light and How it Works
UV light is comprised of electromagnetic radiation of wavelengths ranging from 100 to 400 nanometres (nm). The UV Spectrum is divided into four regions, which are designated Vacuum UV,
UV-A, UV-B, and UV-C. UV-C or short- wave ultraviolet occurs between 200 -280nm and the optimum UV germicidal action at 265nm. It has strong disinfection ability, can physically kill microorganisms by altering or disrupting their DNA or RNA, effectively and chemical free.
CAUTION: UV Light is not visible to the human eye, and is harmful to eyes and skin.
Ultraviolet Disinfection Water System uses one or more Ultraviolet Lamp (UV Lamp) which can effectively emit a germicidal UC-C ray (253.7nm) to disinfect water by killing bacteria, viruses, moulds and algae etc. By correctly using an Ultraviolet Disinfection water system in-line, these organisms can be eradicated fast without and harmful residuals.
Application of UV Light triggers a reaction almost immediately and is more effective that chlorination and other water disinfection systems on a wide range of pathogens.
Safe and chemical free: UV Light does not result in the creation of harmful disinfection by-products; UV Light does not alter water chemistry and its constituents, such as pH, taste, odour or colour etc.
Low Cost: Capital cost is low and operation cost is low comparted to alternative disinfection methods.
Simple and easy to install and operate - mounted vertically or horizontally.
Water Quality Guidelines
The UV Water disinfection system is intended for use with visually clear water, not coloured, cloudy or turbid.
• Ambient Water Temperature: 2-45 deg.C
• Iron: 0.3ppm (0.3mg/l)
• Hardness: <7gpg (120mg/l)
• Turbidity: 1NTU
• Manganese: 0.05ppm (mg/l)
• UV Transmittance: >75%
It is always advised to install a pre-filter before the UV system, this prevents sediments clouding the quartz sleeve and preventing UV Lamp radiation from working effectively.
