Water sources worldwide increasingly face challenges related to iron, manganese, hydrogen sulfide, heavy metals, and organic contaminants. According to WHO and EPA guidelines:

• Iron in drinking water should generally be below 0.3 mg/L (aesthetic limit)
• Manganese should be below 0.1 mg/L (health-based guidance in some regions)
• Hydrogen sulfide causes odor and corrosion even at <0.05 mg/L

Manganese-based materials provide cost-effective and proven solutions for these issues, especially in filtration and oxidation systems.

Primary Function: Iron and manganese removal by oxidation and filtration

Typical Applications

• Groundwater and well water treatment
• Small to medium municipal water plants
• Rural and decentralized water systems

Key Technical Parameters

• Effective particle size: 0.6–1.2 mm

• Suitable iron concentration: ≤10 mg/L
• Suitable manganese concentration: ≤2 mg/L

System Requirements

• Requires chemical regeneration (KMnO₄, chlorine, or NaClO)
• Backwash rate: typically 15–18 m/h

Check Manganese Sand vs Manganese Dioxid in Water Treatment

Manganese-based water treatment materials are commonly evaluated under:

NSF/ANSI 61 (Drinking Water System Components)

AWWA B100 series (filter media guidance)

EN standards for drinking water contact materials

Material selection should always consider local regulatory requirements and system design conditions.

Are manganese-based filter media safe for drinking water?
Yes. When properly manufactured and applied, manganese-based filter media are widely used in drinking water systems and comply with international water treatment standards.

Can manganese sand and manganese dioxide be used together?
Yes. In some multi-media systems, manganese sand and MnO₂ are layered to optimize cost and performance.

How often should filter media be replaced?
Replacement cycles range from 3–5 years for manganese sand and 5–8 years for MnO₂, depending on water quality and operation.
