Overview
EN 13752:2012 (CEN) specifies requirements and test methods for manganese dioxide (MnO2) when used in the treatment of water intended for human consumption. The standard describes identification (chemical name, formula MnO2, CAS 1313-13-9), commercial forms (granular media), physical and chemical properties, labelling, transport, storage and safety. Two product classes are defined by hardness: Class 1 (≥ 6 Mohs) and Class 2 (< 6 Mohs). EN 13752:2012 clarifies performance parameters for manganese dioxide used as a catalytic or filtering medium in drinking water systems and notes that national regulatory approval may still be required.
Key topics and technical requirements
- Identification and composition: Chemical name, synonyms (pyrolusite, manganese(IV) oxide) and EINECS reference are specified.
- Particle size / grading:
- Typical commercial size ranges: 0.355–0.850 mm, 0.50–1.00 mm, 0.5–3.00 mm.
- Particle size may be expressed by effective size (d10 ±5 %), minimum size (d1 ±5 %) or mass fractions.
- Oversize/undersize mass fraction limits: 10% for multimedia filters, 5% for single media filters.
- Uniformity coefficient (U): < 1.5 for products ≤ 1 mm; < 2.5 for products > 1 mm.
- Density:
- Bulk loose density: 1 750–1 850 kg/m3 (≤1 mm); 1 800–2 200 kg/m3 (>1 mm).
- Bulk packed density: 1 950–2 050 kg/m3 (≤1 mm); 2 000–2 400 kg/m3 (>1 mm).
- Oxidation capacity: Minimum of 500 bed volumes under the specified test (see clause 8.2.4).
- Test methods and sampling: Sampling and analysis per EN 12902 and other referenced laboratory standards; particle size, bulk density and oxidation capacity test procedures are defined.
- Safety, labelling and storage: Includes transport and storage guidance, long‑term stability and incompatibilities; Annex B covers safety rules.
Applications
- Use as a catalytic filtering medium for manganese and iron removal and as a pre‑oxidant/filtration support in drinking water treatment.
- Employed in single‑media and multi‑media filter beds, pressure filters and catalytic media layers.
- Relevant to filter design parameters: particle size selection, bed depth, hydraulic characteristics and head‑loss considerations (described in Annex A).
Who should use this standard
- Water utilities and treatment plant operators
- Filter media manufacturers and suppliers
- Drinking water consultancy and design engineers
- Test laboratories and conformity assessors
- Regulatory bodies and procurement teams
Related standards
- EN 12901:1999 (definitions for inorganic supporting/filtering materials)
- EN 12902 (methods of test for inorganic supporting/filtering materials)
- EN ISO 385, EN ISO 3696, ISO 6333 (laboratory and analysis references)
Conformity with EN 13752:2012 supports specification, procurement and quality control of manganese dioxide media but does not replace national approvals or regulatory checks for use in drinking water.
