What is an Ultraviolet (UV) Sterilizer?
UV Water Sterilization technology seeks to use the same process as nature to provide water that is completely safe. In nature, the Sun produces UV rays which have a germicidal effect on disease causing pathogens in water. When these contaminants are exposed to UV light, they are rendered harmless and the output water is considered disinfected.
Our ultra violet water purification systems kills 98% of all bacterial contaminants, and provides clean, safe drinking water, far exceeding Health Department standards for portable water.
UV water sterilizers use several stages of filter to remove sediments down to 5 microns removing particulates. A second stage Carbon filter removes odors and particles down to 0.5 microns. The UV light stage saturates the water with high dose UV light at wavelengths that kill pathogens. Together the UV water sterilizer system is excellent for quality of construction, and effectiveness in treating your water to remove unwanted and unsafe elements. The UV water treatment system is ideal for homes, businesses, and remote sites.
How does it work?
UV sanitation systems eliminate chlorine-resistant microorganisms, which are common causes of pool closures. These systems reproduce UV radiation inside light chambers via powerful lamps, which emit germicidal UV-C light that is used to disinfect pool and spa water. Facilities equipped with these systems consume fewer chemicals and allow sterilizers to be more effective. How much more effective depends on the water's hardness, pH and other water chemistry factors. UV-C causes permanent damage to a number of microorganisms almost instantly as the water circulates through the light chamber. By disrupting the microorganism's DNA, protozoans, viruses and bacteria are unable to replicate and remain inert. This light, however, works only on water that flows through the chamber. Water in dead zones isn't treated by the light and the light does not act as a residual, thus the need for the presence of a halogen. The effects of UV-C are immediate and do not alter the water's composition.
Factors Affecting UV Treatment:
Because UV does not leave any measurable residue in the water, it is recommended that the UV sterilizer be installed as the final step of treatment and located as close as possible to the final distribution system. Once the quality of the water source has been determined, you will need to look at things that will inhibit the UV from functioning properly (i.e. manganese, TDE, turbidity and suspended solids).
Iron and Manganese will cause staining on the quartz sleeve and prevent UV energy from transmitting into the water levels as low as 0.03 ppm of iron and 0.05 ppm of manganese. Proper pre-treatment is required to eliminates this staining problem.
Total Dissolved Solids (TDS) should not exceed approximately 500ppm. There are many factors that make up this equation, such as the particular make up of the dissolved solids and how fast they absorb the available UV energy. Calcium and magnesium, in high amounts, has a tendency to build up on the quartz sleeve, again impeding the UV energy from penetrating the water.
Turbidity: is the inability of light to travel through water. Turbidity makes water cloudy and aesthetically unpleasant. In the case of UV, light levels over 1NTU can shield microorganisms from UV energy, making the process ineffective.
Suspended Solids: need to be reduced to a maximum of 5 microns in size. Larger solids have the potential of harboring or encompassing the micro organisms and preventing the necessary UV exposure.
Pre-filtering is a must on all UV applications to effectively estroy micro organisms to a 98.9% kill rate.

Limitation of Use
The UV water disinfection system NOT intended for the treatment of water that has an obvious contamination or intentional source, such as raw sewage, nor is the unit intended to convert wastewater to microbiologically safe drinking water.
Water Quality (in)
Water quality plays a major role in the transmission of germicidal UV rays. It is recommended that the water does not exceed following maximum concentration levels
Effectively treating water with higher concentration levels than listed above can be accomplished, but may require added measures to improve water quality to treatable levels. If, for any reason, it is believed the UV transmission is not satisfactory, contact the factory.
