PA Series Ultraviolet Disinfection Systems-Silver Series. This modular line of ultraviolet disinfection systems can be used in a myriad of applications where flexibility and pricing sensitivity is a deciding factor. The small SQ-PA through S2Q-PA systems are ideally suited for point-of-use filtration, RO pre or post disinfection, while the larger S5Q-PA, S8Q-PA and S12Q-PA systems can be used on a point-of-entry system, disinfecting the water for an entire home or cottage. The low pressure germicidal lamps provide an economical way of treating water requiring a 99.99% reduction in bacteria and viruses.
These simplistic designs allows for easy homeowner maintenance. The UV lamp can be changed without interrupting the water flow. The quartz sleeve design allows for maximum UV output and operating efficiency.
WATER STERILIZATION BY ULTRA VIOLET LIGHT
Ultraviolet light is emitted by the sun and is the natural way of destroying water-borne bacteria.
Ultraviolet light is also produced by converting electrical energy in a germicidal lamp, made of special quartz glass, enabling ultraviolet rays to be emitted efficiently and safely very similar to neon light being transmitted from a fluorescent lamp.
Water contaminated by bacteria or virus can be sterilized effectively by circulating it through ultraviolet rays from a germicidal lamp enclosed in a 304 stainless steel chamber. The unique advantage of this method of sterilization is that nothing is added to the water...no chemicals, therefore no dangerous handling, unpleasant odor or taste, or change in water composition.
Water sterilization by ultraviolet light is very versatile and has numerous applications:
It produces germ-free potable water from wells, cisterns, tanks and pools by destroying bacteria caused by seepage of surface water or sewage and algae and slime formation. It provides bacteria-free food process water, without the use of germicides, oxidants, algaecides or chemical precipitants, for maintaining rigid product quality control, safe guarding against spoilage from chlorine and enabling sanitized processing. It prevents bacteria incubation wherever chlorine-free, deionized and/or carbon-filtered water is used, and assures high standards of purity and sterility in all water systems.It affords excellent end-treatment for protection in waste water control systems, and destroys bacteria after removal of chemicals and other objectionable ingredients
Water sterilization by ultraviolet light offers several advantages:
The amount of ultraviolet light required to kill the various kinds of micro-organisms which are dangerous to humans and animals varies. Careful experiments have determined the dosage required to achieve virtually a one hundred percent kill result by altering the D.N.A. structure so that the micro-organism can no longer multiply.
The dosage is expressed in microwatt seconds per square centimeter (mws/sqcm). It is a combination of the strength of the ultraviolet light and the time it must penetrate each square centimeter of the water. Below listed is a table which shows the dosage required to kill some common bacteria and viruses:
WHAT IS ULTRAVIOLET ENERGY?
Ultraviolet energy is natures own light. The sun constantly supplies large amounts of light and heat. Some of the light supplied by the sun can be seen, while other rays are beyond the vision of the human eye. Ultraviolet light is invisible to the human eye. The difference between visible and invisible light lies in the wave length. Wave length is usually measured using a very small scale measure known as Angstrom "A" or nano meter.
As an example:
Ordinary light emitted by a light bulb = 3'800 -7'800A
Green color from a leaf of lettuce = 5'460A
Ultraviolet light = 1,000 - 3'800A
The wave length used to kill bacteria and viruses lies between 2'— and 2'800A. It has . been determined that wave length 2'537A or 254 nanometers are considered as the optimum in killing bacteria and viruses.
