To remove dissolved iron and prevent staining water, softeners or salt-free water filters can be installed. Water softeners remove dissolved iron and hardness using ion exchange. These systems recharge themselves with salt that is consumed but adding virtually no salt to the water itself. However, they do require routine filling of the salt tank by the homeowner. We also install treatment systems with a salt-free design that remove iron and sulfur odor by oxidizing the dissolved iron and hydrogen sulfide gas into a filterable form and then backwashing this precipitate out. This treatment does not require filling of salt or chemical tanks. The size of the water treatment system depends on the required flow rate of the well and pump system and if the water used for irrigation must be treated as well as the domestic house water.
