Nimbus Water Systems Inc. R-Can Sterilight Disinfection Ultraviolet Systems

The Sterilight Process
Sterilight ultraviolet water sterilizers incorporate natural ultraviolet light energy to eradicate microbiological contamination. Sterilight Protects Water Natures Way... Water enters through the bottom port of the ultraviolet reactor chamber and swirls around a low pressure mercury vapour lamp thermally protected by a quartz sleeve. The UV lamp emits powerful ultraviolet light energy at a wavelength of 253.7 nm. Vital genetic components contained in microorganisms absorb the light energy; this disrupts the DNA and prevents reproduction. Treated water then exits through the top port of the generator cell and is ready for consumption.

Natural Purification
Sterilight incorporates modern technology to solve an age-old problem. Bacteriological contamination can be present in all water supplies, especially rural areas or areas which are not treated with municipal water systems. It is recommended that no surface waters be consumed without adequate microbiological treatment, regardless of how the water is tested. Sterilight protects your water Natures Way by using cleansing ultraviolet light. Unlike traditional disinfection methods such as chlorination (which can not only react with natural organic matter in water to produce objectionable taste and odour, but also form substances with known carcinogenic properties such as trihalomethane), UV imparts no residual chemicals into the water. The result is the most simple, cost effective way of treating your water!

Product Features
Sterilight products are designed to provide maximum UV output while remaining very user friendly. Some of the many features include:
• 304 or 316 polished and tested stainless steel reactor chambers
• Quartz sleeves for optimum operating temperatures
• 254 nm hard glass UV lamps with ceramic bases for durability and efficiency
• Lamp out alarms for audible and visual recognition
• True 254 nm UV monitors with various output devices including LED’s, meters and remote monitors
• Anodized rust resistant enclosures as well as full stainless steel enclosures
• Thermistors for control panels and reactor chambers
• Elapsed time meters
• Solenoid valves and remote metering equipment including infrared outputs
• Sanitary fittings and electro polishing for high purity applications
• Units manufactured in most electrical configurations to satisfy global markets

Proven Performance
The UV dose (fluence) delivered by a given reactor is dependent on many factors, including water quality and flow rate. It should be noted that flow rates are Dose Dependent. By this, we mean that the flow rate will vary dependent on the specific dose required. A UV dose at the 16 mJ/cm2 U.S. Public Health recommendation will result in a flow rate that is approximately 2 1⁄2 times higher than a dose at the new 40 mJ/cm2 NSF Std. 55 protocol. R-Can recommends that you choose the applicable dose requirement that suits your application. Once this is done, select the unit that you wish to purchase by referring to the Dose-Flow charts included with our individual specification sheets. The dose that is right for you will be a factor of many issues, however for those applications where general disinfection is proposed we propose the 30 mJ/cm2 “R-Can Standard”.
