Using Chlorinator Systems To Remove Bacteria

AWWA_Illustration 105The US Environmental Protection agency strongly recommends annual coliform bacteria testing for private water wells, as contamination can occur without any change in taste or odor to the water.

It is best to address your bacteria problem as soon as possible in order to keep it under control, and will even save time and money in the long run.

If your well has recently tested positive for coliform bacteria, a chlorination system can be the best method for removing bacteria.

Chlorine can be easily and inexpensively injected into water to kill bacteria, inactivate viruses, and/or treat water for odor, iron or manganese.

Why use a water well chlorinator?

The main advantages of chlorination is that the chlorine injection is relatively inexpensive to set up, and the chlorine residual can also be inexpensively detected in the distribution lines of the piping system, assuring proper disinfection.

In other words, unlike UV sterilizers or ozone, which are also used for disinfection, a chlorine residual can be easily detected, which usually means the water is properly disinfected.

The most common way to chlorinate home or small community water systems is by the use of a metering pump which pumps a small amount of liquid chlorine bleach into the water. Sufficient contact time must be allowed for the chlorine to be effective.

A carbon backwash filter can be used to remove the chlorine before it enters the home if desired.

Liquid chlorine (bleach) is injected right out of the well, before the pressure tank. Typically a contact tank is used to allow sufficient contact or retention time for the chlorine or hydrogen peroxide to work properly.

Here is a diagram of a typical installation of a chlorinator system. These systems are designed to be easily installed by any plumber or person familiar with basic plumbing:

Which chlorinator (metering pumps and solution tank) should I get for my application?

If you are a homeowner with a well pump that has a 1/2 hp to 1 hp pump, our chlorinator J-PRO Series pump systems provide the lowest maintenance and are the easiest to use. These systems are easily adjustable to get the correct chlorine residual you need.

If you want to use a pellet feeder, we also offer chlorine pellet feeders that drop chlorine pellets down the well each time the well runs. The chlorine residual can be a little harder to control with a chlorine pellet feeder and are more expensive to operate than the Stenner systems which use chlorine bleach.
