INTRODUCTION – DESCRIPTIONS AND DEFINITIONS You have purchased one of the most technologically advanced Ultraviolet Water Treatment System available anywhere in the world. It has been designed with you, the consumer, in mind. PURA® products are lightweight, easy to use, and simple to maintain. PURA products will provide you with healthy, clean drinking water for years to come. WHAT IS ULTRAVIOLET? Ultraviolet (UV) light from the sun has long been known for its ability to destroy microorganisms. However, it has only been in recent years that equipment producing UV light has been manufactured for residential use. WARNING: NEVER LOOK DIRECTLY AT A LIGHTED UV LAMP. ULTRAVIOLET RAYS CAN BE HARMFUL TO EYES. UV energy is produced by low-pressure mercury vapor enclosed in a tubular lamp. While a UV lamp resembles a standard fluorescent lamp, it is similar in appearance only. Energy produced by the UV lamp has the ability to destroy microorganisms that can live in water. There are five major groups of microorganisms that are altered by a specific spectrum of ultraviolet light: viruses, bacteria, fungi, algae, and protozoa. When these microbes are exposed to the proper amount of UV energy, their DNA structure is scrambled, and they are unable to reproduce. Since the cell is now sterile or dead, it is no longer a threat. WHAT IS ACTIVATED CARBON? Activated carbon has been used for hundreds of years to treat taste, odor, and color problems in water. Activated carbon has been proven to be an excellent media to produce better tasting water and to remove harmful water contaminants at a reasonable cost. Carbon used for filters may be manufactured from wood, coal, or coconut shells. The raw carbon is ground up and “activated” by heating the granules at a controlled temperature and pressure. This process causes the carbon granules to expand and create active sites where pollutants can be collected by adsorption. These new sites dramatically increase the total surface area and capacity of each granule. WHAT IS ADSORPTION? Adsorption is the physical process where certain water pollutants are attached to the surface of carbon particles as the water flows through the filter. The pollutants are removed from the water and locked into the carbon granule. Activated carbon is also able to filter out sediment through a process of mechanical filtration. The particles are captured in the spaces between carbon granules. PURA SYSTEMS PURA recommends that all UV systems include pre-filters to process the water before it reaches the UV lamp. This will ensure that maximum UV exposure is achieved. PURA UVB, UV20 and UVBB series offers integrated filters in a single system. These integrated systems use a two-stage filtration process: First, a string-wound filter removes the suspended solids that may shield the microbes and make it difficult to obtain sufficient UV exposure. Second, an activated carbon filter removes unpleasant tastes and odors. PURA Ultraviolet Water Treatment Systems are designed for indoor use only. PURA Systems are designed to provide complete water treatment in a compact, easy-to-use package. Please follow the directions in this Guide exactly when installing your PURA System to ensure that it operates correctly. The UV lamp requires a start-up period of one to two minutes in order to achieve full intensity. Repeated starting of the UV lamp will shorten its life. Therefore, it is recommended that the UV lamp remain on at all times during use.
