How To Use a Proportional Feed Chlorinator to Kill Bacteria and Eliminate Odors


Hello John, 

Based on the concern that we read from your email: 

"I have a constant pressure pump and want to install a chlorinator.  How can I turn the chlorinator on and off automatically?   I only want to chlorinate the water inside the house.

Our well water tested positive for iron bacteria that has odors, and rust.  I have a small amount of arsenic (2 ppb) and want to use a reverse osmosis filter for drinking.  Will this remove the arsenic?   Currently we do have a water softener."



Thanks for sending in your test report.

Considering your contaminant levels as well as the positive for bacteria you are correct in your assessment of the equipment necessary, as well as a Carbon Filter for chlorination removal.  I’ve put the following together for you, we can also extend a discount based upon the order placed.

How this application will work is the chlorine (mixed with water) is injected whenever the water flows through the Flow Meter which well then energize the Metering Pump to begin injecting solution based upon the rate of flow.  Once injected the 120 gallon contact retention tank allows for enough contact time for the chlorine to destroy the bacteria, oxidize the iron, etc. for removal and then simply be filtered by first a Pro-Ox Iron Filter and Carbon Backwash System.

The Proportional Flow Chlorinator will allow us to only inject the chlorine solution based upon water flow and not say a well pump running.  Installation is much simpler as well, simply plug the Metering Pump into a standard 110 Volt outlet and connect the two dry contact wires at the Metering Pump to the two dry contacts on the Flow Meter.

The Precision-24 self-priming chlorine pump systems are easy to install by anyone familiar with basic plumbing and very easy to maintain yourself.  Settings for the pump will be provided as well as the ratio of bleach/water to be used.

As a safety barrier since we are dealing with Arsenic we also recommend installing an under-sink Reverse Osmosis unit at the kitchen for drinking water. 

The end result is clean, disinfected, odor-free, chlorine-free water throughout the home with minimal maintenance required.
