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.
