China Iron and Manganese Removal Filter Suppliers - Efficient Groundwater Treatment Factory
Equipment Description
The filter material of the iron and manganese removal filter consists of manganese sand, anthracite, and quartz sand. The primary filtration medium is manganese sand, with quartz sand and gravel serving as the underdrain support layer. This equipment is primarily designed to remove manganese and iron ions from influent water through catalytic oxidation by manganese sand adsorbents.
It can be configured for either manual or automatic control, with the ability to switch between these modes. The automatic control system monitors and regulates all operational and process control points, enabling unattended and fully automated operation. The system employs a combined air-water backwash mechanism, and the backwash wastewater is discharged. Additionally, the concentrated water from the reverse osmosis system is utilized for backwashing in the system design, thereby enhancing water utilization efficiency.
During backwashing, the filter can initiate automatic backwashing based on the time interval set by the central control system or according to the differential pressure threshold across the inlet and outlet of the filter.
The operational modes of the filter include water production, water backwashing, air backwashing, and forward washing. All operational modes are executed automatically in accordance with predefined programs.

Frequently Asked Questions (FAQ)
What filter materials are used in this iron and manganese removal filter?
The filter media consists of manganese sand, anthracite, and quartz sand. Manganese sand serves as the primary filtration medium for catalytic oxidation, while quartz sand and gravel provide underdrain support.
How does the system control and automate its operations?
The system features both manual and automatic control modes. In automatic mode, the control system monitors and regulates all operational processes, allowing for fully automated and unattended operation.
What triggers the backwashing process and how is it executed?
Backwashing is performed using a combined air-water mechanism. It can be automatically triggered based on a preset time interval or when the differential pressure across the inlet and outlet reaches a specified threshold.
How does the filter design improve water conservation?
To improve water utilization efficiency, the system design allows the concentrated water discharged from downstream reverse osmosis systems to be recycled and used for backwashing the filter.
What are the influent and effluent water quality limitations?
The filter is designed for influent iron and manganese concentrations of 5–15 mg/L. It achieves high-efficiency purification, ensuring effluent iron levels are ≤ 0.3 mg/L and effluent manganese levels are ≤ 0.1 mg/L.
