Iron and manganese are common contaminants in groundwater, causing aesthetic issues like staining and discoloration, and posing potential health risks. Ferrosand, a type of granular filter media, has long been a reliable solution for removing these pesky metals from water supplies.
What is Ferrosand?
Ferrosand is a naturally occurring, granular material composed primarily of iron oxides. It functions as a catalytic oxidizer, promoting the conversion of dissolved ferrous iron (Fe2+) and manganous manganese (Mn2+) to their less soluble ferric (Fe3+) and manganic (Mn4+) forms. This conversion triggers the precipitation of iron and manganese, effectively removing them from the water.
Hungerford & Terry, Inc.: A Leading Supplier of Ferrosand Filtration Systems
Hungerford & Terry, Inc. is a renowned manufacturer of water treatment systems, specializing in the removal of iron and manganese. They offer a range of Ferrosand filter media, designed to meet specific water quality challenges. Their filter media is carefully graded and processed to ensure optimal performance and longevity.
Benefits of Using Ferrosand:
How Ferrosand Systems Work:
Ferrosand filter systems are typically composed of a tank containing the filter media. Water flows through the bed, where the oxidation and precipitation processes occur. The precipitated iron and manganese are trapped within the filter bed, requiring periodic backwashing to remove the accumulated solids.

Scenario: A homeowner is experiencing rust-colored water stains in their sink and bathtub. They suspect iron contamination in their well water.
Task:
**1. Explanation:** Ferrosand is a highly effective solution for removing iron from water. It works by oxidizing the dissolved iron, converting it to a less soluble form, which then precipitates and gets trapped in the filter bed. This process eliminates the iron causing the rust stains. **2. Recommendation:** Based on the information provided, a Ferrosand system would likely be a good solution for this homeowner. Since they are experiencing rust stains, it strongly suggests iron contamination in their water. Ferrosand is specifically designed to address this issue, offering a reliable and long-lasting solution. However, it is always advisable to have the water tested by a qualified professional to confirm the presence and level of iron before investing in a treatment system.
