How do I know what type of chemical feeder system I need?
There are many different types of chemical injection applications. The
majority of situations for private home owners deal with sulfur, pH issues or
iron bacteria. In some cases they also help treat for e-coli or coliform
bacteria. Virtually all of these situations can use the same chemical feed pump.
For sulfur you would add an average of 1 cup of Clorox to 15 gallons of water
and inject it into the water line. The sulfur gas and the Clorox will
neutralize each other so that you won't get a reading on either
one.
For pH problems that deal with acid water you would normally feed a mixture
of water and soda ash. If the pH is really acidic (low) you may want to use
caustic soda or switch to an acid neutralizer backwashing tank. It is usually a
good idea to switch to a backwashing tank if your pH is 5.5 or lower. If your pH
is below 5.0 you may want to consider a backwashing tank with two different
medias inside. One to get it over 5.5 and the other to bring it the rest of the
way.
For iron bacteria you would normally add about 1/3 gallon Clorox bleach to 15
gallons of water, then run it through a Terminox
iron filter.
You can mix BOTH soda ash and Clorox if necessary in the same mixing tank.
INSTALLATION: You would normally install the chemical pump BEFORE the
pressure tank and AFTER the well pump. If you want to add the chemical pump
after the pressure tank you must add a FLOW SWITCH. The flow switch would tell
the pump when the water is moving and turn the pump on to inject.

your water including e.coli, lead, pesticides and
nitrates.
