SEPARATE UV STERILIZER
There are also set-ups where the UV sterilizer is
separate from the filter and pump. Though the units
are separate, they work in conjunction with each other.
Like the previous system, the water goes in and out,
but it’s just set up a bit differently. This type of sterilizer
may not sit inside of your system, but piping will
create intake and outlet points for the water to move.
“THE WATER in your system
is drawn into the sterilizer,
is exposed to the UV light,
goes through a filter, and
gets pumped back out of it.”
IN-LINE UV STERILIZATION
Another option is in-line UV sterilization, which allows you to sterilize your lines and the
water flowing through them. This means water is treated as it flows into the treatment
area. This configuration is helpful when using beneficial microbes in your set-up and
reducing the problems with nutrient reduction as it may not be as impactful. However,
if you already have a problem with algae, bacteria, or fungi in your system, this set-up
does not help eliminate it. Any algae attached to the walls and other surfaces needs to be
removed another way.
BIGGEST DRAWBACK WITH UV STERILIZATION
One of the biggest drawbacks in using UV sterilization is that it can deplete some of
the things your plants need to grow healthy and strong. Iron, boron, and manganese
deficiencies can occur when using UV sterilization. Also, UV sterilization reduces
the populations of any beneficial microbes in your hydroponic set-up much in the
same way it does the fungal, bacterial, and algal populations. It’s beneficial to
test your hydroponic system for these deficiencies to help minimize them.
Ultraviolet sterilization can be an excellent option for keeping your
system free of bacteria, fungi, and algae that can turn your set-up
into a nasty problem. While it does have drawbacks, proper
management and testing can help to reduce these issues.
Once set up and dialed in, UV sterilization can give
you clean and clear water that makes you
and your plants happy.
