Using UV radiation in this manner to purify water is popular among Europeans
who have known about it for decades. It's used in the United States started in the
early 1990sand is becomingmore prevalent especiallywith outbreaks ofdrinking
water contamination by microorganisms. The UV purification system
incorporates a lamp of suitable size and wattage to generate light of the proper
wavelength withan electronic ballastto operate it.The electronic ballast plays an
important role in how much UV the lamp generates. Dosage is a function of UV
wavelength, intensityand time. Lightintensity from the lamp is proportional to the
electric current flowing through it, and is also affected by the frequency at which
it's operated. Both of these parameters are controlled by the electronic ballast.
Since many water purification systems are portable, they sometimes require
power supplied from a battery rather that the typical AC source, i.e.,220 -volt
outlet. The electronic ballast must be able to accommodate applications with this
requirement. Some of the other features users might expect from the electronic
ballast aresmall physical size,long life andhigh efficiency.
At least one line of electronic ballasts can help meet these requirements. It can
operate a wide variety of germicidal lamps from a number of different power
supply voltages including both AC and DC (battery) sources. Many models are
compact in size and can be easily incorporated into most designs. Probably one
of the most attractive features of the product line is that nearly any model can be
customized for a specific lamp to generate different levels of UV radiation. In
some cases, new or specialty lamps require new ballast designs. In these
instances, engineers can often create designs that meet or exceed customer
needs. UV irradiation is becoming a more viable and economical means of water
purification whenused in conjunctionwith other methods.
