UV sterilization is
used to stop the spread of microorganisms from invertebrates, coral, and fishes
to another through the water. It is widely used in pond applications to control
free-floating algae. Not only this, when UV sterilizer is used accurately with
all of its features and characteristics, it can kill the microorganisms that
must be in the water that flows to the UV sterilizer. The UV light has no
residual effects so that it can’t kill any healthy and attached organisms to
fish – for instance, adult stage of ich and algae.
How Do UV Sterilizers Benefit in Killing Microorganisms?
The UV sterilizer is
designed with a germicidal fluorescent lamp that emits light at a wavelength of
around 254 nanometers. The water with bacteria and algae passes through or
around the bulb and is irrigated with the wavelength if a quartz sleeve is
used. As the light enters the bacteria, it mutates the DNA, limiting the growth
of an organism.
What Factors Impact the effectiveness of UV sterilizers?
Many factors influence
the effectiveness of UV sterilizers, but only a few of them are discussed
below; let’s talk about them:
Size and type of
organism:
The UV rays kill any
bacteria, algae, and protozoa. However, in larger ones, the same as protozoa, a higher dose of UV radiation is required than killing smaller objects bacteria,
for instance. Besides, various organisms are more resistant to UV radiation.
Power of Bulb:
The amount of UV light
emitted out by the bulb is reflected in the wattage – for instance, a bulb with
a higher wattage produces more light and vice versa. Moreover, UV light is best
produced at 104 to 110 degrees, cooler temperatures resulting in less output.
UV penetration:
If the UV light is
designed with features that don’t allow it to penetrate through the water, it
might not be an effective solution to decompose bacteria. They must be placed
after the mechanical and biological filters, so the water is as clear as
possible when it enters the sterilizer. Remember, UV light penetrates well in
freshwater as compare to salty water.
Note: You can
easily buy it from any UV sterilizer manufacturer at reasonable rates.
And, please don’t ever run for the cheapest ones, as it won’t work out great
compared to one with a good price, Happy Shopping!
