The Liquid Chlorination water treatment system injects chlorine into the water stream to
remove iron, sulfur, manganese and bacteria from water source. Chlorine is injected into the
water stream proportionally. The chemical injection control panel will engage the pump based
on the flow rate of the feed source water and the settings on the pump control.
When water is being used the water meter on the injection panel sends a pulse to the pump
control to engage the pump. So when large amounts of water are being used the pump will run
more frequently during the usage period than in times when small amounts of water are being
used.
When chlorine is injected into the water stream, it oxidizes the iron, sulfur, manganese and
bacteria and causes it to precipitate from solution. This reaction requires retention time to fully
react. When these contaminants are oxidized they can be removed from the water stream with
a GAC carbon filter.
Once the water has been injected with chlorine it passes through the retention tank to provide
reaction time, the water passes through the backwashing carbon filter. The backwashing
carbon filter uses GAC carbon to remove the oxidized/precipitated contaminants. As the water
passes through carbon filter the contaminants are removed from the water and collected on the
carbon media. Once the water has passed through the carbon filter the water is iron, sulfur
and bacteria free. Any residual chlorine is removed as well.
The carbon filter will need to be backwashed on a frequency (in days) to flush out the collected
contaminants. The frequency varies on each system depending on the contaminant level.
Please use the following table as a guideline for backwash frequency combining iron and sulfur
values (these are baseline values and actual frequency may vary);

How the Liquid Chlorination Water Treatment System Works
Following the carbon filter are two sediment filters. The first is a 5 micron and the second is a 0.5
micron. Both are housed in a dual filtration system. These filters remove the fine particles that may
have made it thought the carbon filter and other system components.
