The Fusion Oxi-Gen iron and sulfur eradication system uses Hydrogen Peroxide (H2O2) to
oxidize contaminants in the water source. The chemical name for hydrogen peroxide is H2O2.
It is very similar to water (H2O) but with one additional oxygen molecule. Hydrogen peroxide is
injected into the water stream proportionally. The water meter will engage the chemical
injection 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 sends a pulse 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 a small amount of water is being used. The standard programming is set to
a 5 second control. At 100% the pump will stay engaged for 5 seconds. At 50% the pump will
stay engaged for 2.5 seconds. In some applications with high flow rates or high contaminant
levels, this setting may need to be changed if a residual H2O2 cannot be achieved. There are
internal settings that can be changed to adjust the output rate. The pump settings can be
changed to 10 seconds at 0-100% or 20 seconds at 0-100% if need be. 80% of the
applications will use the standard setting (5 seconds).
When hydrogen peroxide is injected into the water stream, it oxidizes the iron and sulfur
precipitating it from solution. This reaction is immediate. When these contaminants are
oxidized with hydrogen peroxide (H2O2) the extra oxygen molecule oxidizes the contaminants
and the by product is H2O (water). This is much safer than using chlorine in that chlorine can
cause other problems in the water stream such as chloramines and trihalomethanes (THM’s).
Once the hydrogen peroxide has been injected in the water it passes through the backwashing
Catalytic Carbon filter. The backwashing Catalytic Carbon filter uses Catalytic Carbon media
to act as a “catalysis” to remove the oxidized contaminants. As the water passes through
Catalytic Carbon filter, the oxidized contaminants are removed from the water and collected on
the Catalytic Carbon media. Once the water has passed through the Catalytic Carbon filter,
the water is iron and sulfur free! Some manganese can be removed with the Fusion Oxi-Gen
system buy extreme levels of manganese may require a water softener in addition to the
Fusion Oxi-Gen system to polish the remaining manganese.
The Catalytic Carbon filter will need to be backwashed at a specified/determined frequency. In
some applications this can be extended to 4-5 days. The typical frequency is 1-3 days.
Contact US Water Systems and a Certified Water Specialist will be able to determine the
frequency that can be used when considering the feed water contaminant levels. The factory
default will be 3 days.
