Some of my family member are sensitive to chlorine and
are frightened of copper sulfate.
I need to kill algae (green, stinky, slimy) this summer
in my swamp cooler. Is there a powder of ozone I can drop
I know the water treatment people use both ozone and
chlorine. I wonder where they are getting their ozone from?
I don't live in an area where swamp coolers can work, but I seem to
remember that there are products designed for what you want. Try a HVAC
supply store in your area, maybe even the Home Depot type places may have
dont kill algea......
its the new clean green source of ethanol.
take power plant exhaust, run it thru algea tubes, exhaust now 40%
cleaner:) the algea grows great in co2 exhaust, algea filtered out and
fermented into ethanol.
its a closed system no water wasted.........
now food crops used for fuel either
Ozone is O3. A diatomic molecule of Oxygen O2 is split by
UV light or a high voltage discharge into two atoms of
Oxygen which then combine with a diatomic molecule of O2
to form O3.
The third oxygen atom is loosely bound and will separate
and combine with and Oxydise molecules so killing bacteria.
Water treatment can be by UV light, Ozone or more recently
Ultrasonic. The Ozone being produced by a high voltage
corona discharge or ionization of the air.
I can't believe you actually replied with that to a wise crack with that.
Do you really think anyone in this NG is interested in that level of info?
Anyone who want's that level can Google it...like you did
No. Ozone can only be made at the time of use, and is formed in a gas
stream. You can use an aquarium pump, eductor, and flow the ozonated
water into the drain pan in a couple of places. This is how it is
done in cooling towers. You don't want to splash ozonated water
around, and people sensitive to chlorine may be sensitive to ozone in
Either the air, or delivered oxygen. And electricity.
Stupid question, what kind of blow down schedule do you perform? I
have settled on a continuous small trickle. I have also installed a
strainer on the flow to the spider, to capture algae to keep from
spreading algae that way. (I had to go to a more powerful pump to
overcome the backpressure.)
I have no algae at all, but I do live in the desert...

By blow down, I am presuming you mean how often do I drain
my coolers. About every two weeks.
I also have a hose connected to the overflow tube. The
heating and cooling of the chains at night (the chains
shrink at night) will cause about two gallon to drain
down the tube (on to the dry spots on my lawn).
The algae forms inside my blue filter pads, especially
after a blowing dirt storm.
I have been told there is some kind of soap out
there that will work, but have not been able to
The blue pads come soaped with something. Anyone
know what that soap is?
That is not enough, but you are about to alter that amount...
Better. I get about 5 gallons per day (having never actually measured

... there are no miracle chemicals ...

Most important seems to be, run the fan with the pump off every 24
hours to control algae. Probably at night, when it is cooler.

Ozone is actually quite easy to make. You just run a static discharge
through air. You could blow air through a tube with two electrodes with
a high voltage potential and blow outlet into water. What would be
more difficult is measuring output or determining how much is needed.
There are no compounds I know of to generate ozone and the pure gas can
be explosive in high concentration.
Agreed. This will probably work best. Ozone can be expensive to
produce continously plus you have the expense of replacing the UV lamp
periodically if you go that route.
Electrostatic air cleaners produce ozone in low concentrations.
Negative ion generators produce ozone.
Tesla coils produce ozone (and possible RF interference).
Electrostatic Generators (Van de Graph - Whimhurst) produce ozone.
Jacobs ladders (conductive rods connected to Neon transformers)
produce ozone with their dancing sparks (as in Dr. Frankenstein's
Too much ozone is poisonous and not good for you. (It doesn't take
much to reach this threshold.)
