Iron, Manganese, & Calcium/Magnesium
Iron is a prevalent element in the Earth’s surface and subsurface layers. Beneath the crust lies the mantle, a dense, semi-solid layer of rock about 2,900 km thick, which contains higher concentrations of iron, magnesium, and calcium compared to the crust. Due to the constant movement of tectonic plates and shifts within the Earth’s structure, iron is frequently in contact with aquifers and groundwater, increasing the likelihood that it will dissolve or be absorbed into water supplies.
Iron is typically found in a reduced, dissolved state (ferrous iron, Fe²⁺) in groundwater, where it remains clear. However, when this ferrous iron is pumped to the surface, it becomes unstable and reacts with oxygen, chlorine, chloramines, or other elements. This reaction transforms the ferrous iron into ferric iron (Fe³⁺), often leading to rusty or discolored water. The process of iron precipitation generally begins after the water is extracted from the ground and enters the distribution system.
By introducing our water treatment solutions at the point where the water is pumped—before chlorination—iron precipitation can be effectively prevented. Our treatments stabilize the ferrous iron, keeping it in its dissolved, clear state, rather than allowing it to oxidize and precipitate as rust.
Iron, along with calcium and manganese, can also contribute to mineral scale deposits on the inner surfaces of water distribution pipes. These deposits can reduce pipe capacity and, in some cases, break loose, leading to rusty water complaints. Our water treatment products gradually dissolve these deposits and, once the scale is reduced to a manageable level, form a protective barrier on pipe surfaces to minimize further corrosion.
Please explore our range of water treatment formulations to find the best solution for your needs. Our products are highly effective iron sequestrants for potable water and irrigation systems.
