4 Steps on How to Remove Rust from Drinking Water
Rust is commonly regarded as one element but is actually
composed of several compounds that consist of iron and oxygen. Rust forms when
free iron is exposed to oxygen and water. The water color in your home could be
yellow, orange, or brown depending on the concentration of the rust. Typically,
rusty water pipes on a well water system will have a higher concentration of
iron leading to rusty water issues. Thankfully you can remove rust in your home
with water
softeners, oxidizing filters and sequestration.
Step 1: Connect an ion exchange water softener to
your water supply. This device will contain sodium that will combine with the iron
and remove the rust from your water.
Step 2: Install an oxidizing filter before the water softener
line. This device will contain manganese oxides that will convert soluble compounds
into insoluble compounds, which then will filter out of the water. Oxidizing
filters are most appropriate for treat water with a moderate level of
concentrated iron and where the pH is at least 6.8
Step 3: Use a solution feeder to add polyphosphates
to your water supply. Polyphosphates contain phosphorus, which disperse in the water
so the iron doesn’t form rust. However, a polyphosphate chemical feeder can be more
expensive than other options. It is only recommended to use a polyphosphate feeder
if the rust issues are severe enough warrant this option.
Step 4: Add about half gallon of bleach to your water
supply. After adding the bleach, allow to water to sit for about 12 hours and
run the water until no more bleach is present in the system. This system is most
effective when the rust in your water is being produced by bacteria.
