Iron and Manganese Removal Water Filtration System

Product Overview

The Iron and Manganese Removal Water Filtration System is an advanced automatic water purification device specially designed for removing excess iron (Fe²⁺/Fe³⁺) and manganese (Mn²⁺) from groundwater, well water, and industrial water sources.
The system integrates oxidation, filtration, and automatic backwash into one compact unit, effectively reducing iron and manganese concentrations to meet drinking water and industrial standards.
It features high efficiency, stable operation, and fully automatic control, making it ideal for continuous and unattended operation.

Working Principle

Raw water first passes through an aeration or oxidation stage, where dissolved iron and manganese ions are oxidized into insoluble oxides (Fe(OH)₃, MnO₂).
The oxidized particles are then trapped within a special catalytic filter media bed (such as manganese sand or Birm).
Clean water flows out through the outlet, while the retained solids are periodically removed by an automatic backwash process controlled by a pressure differential or timer.
The system may include an air injection system, ozone oxidation unit, or chemical dosing device depending on the raw water characteristics.
