SS304 Sand Filter Solution for Iron and Manganese Removal

SS304 Sand Filter Solution Product Introduction

The SS304 sand filter solution is an advanced filtration system engineered for removing iron (Fe) and manganese (Mn), two common contaminants in groundwater and industrial water supplies.

Excess iron and manganese can cause:

• Discolored water and metallic taste
• Pipe scaling and equipment fouling
• Reduced flow capacity and pressure loss
• Increased maintenance and operational cost

This filtration system uses manganese sand media (MnO₂ 35–45%) to oxidize and remove dissolved metals, delivering clean, stable, and safe water output.

Industry Challenges

Water systems affected by iron and manganese often face:

• Persistent staining and poor water quality
• Pipeline blockage and scaling buildup
• Reduced equipment lifespan
• Complex treatment requirements

A reliable oxidation-filtration solution is required for long-term performance.

System Structure

The SS304 sand filter system consists of:

• SS304 stainless steel pressure vessel
• Manganese sand filtration media bed
• Inlet distribution system
• Underdrain collection system
• Backwash control system
• Drain and vent valves

Modular design ensures long-term stable operation and easy maintenance.

Working principle

1. Water Inlet Distribution

Raw water enters the filter tank and is evenly distributed across the media layer.

2. Oxidation Reaction Process

Manganese sand (MnO₂) catalyzes oxidation of Fe²⁺ and Mn²⁺ into insoluble forms.

3. Filtration and Adsorption

Oxidized particles are trapped within the sand media through adsorption and interception.

4. Clean Water Output

Filtered water flows out with significantly reduced iron and manganese content.

5. Backwash Regeneration

Filter media is regenerated via backwashing or potassium permanganate dosing.
