Overview
EN 16003:2011 is a European Standard developed by CEN that specifies requirements for the use of calcium magnesium carbonate (dolomite) as a chemical for the treatment of water intended for human consumption. This standard outlines the characteristics, purity criteria, test methods, and product handling guidelines to ensure the safe and effective application of calcium magnesium carbonate in drinking water treatment systems. Its aim is to support consistent quality and safety in water purification across the EU and EFTA member states.
Key Topics
Product Identification
- Chemical name: Calcium magnesium carbonate
- Common name: Dolomite
- Chemical formula: CaCO₃·MgCO₃
- CAS Registry Number: 16389-88-1
Physical and Chemical Properties
- Available in crushed and granular forms, typically white, grey, or brownish in appearance
- Density ranges from 2.2 to 2.9 g/cm³, bulk density from 1.2 to 1.6 g/cm³
- Solubility in water: 0.032 g/L at 10°C
- Reacts as an alkali in water, increasing pH and hardness
Purity Requirements
- Minimum of 95% calcium magnesium carbonate in dry substance
- Minimum of 39% magnesium carbonate
- Impurities such as arsenic, lead, cadmium, and chromium are restricted to very low levels to ensure safety
Testing and Analysis
- Sampling and analytical procedures must conform to relevant EN and ISO standards, such as EN 12485, ISO 3165, and ISO 6206
Labelling, Storage, and Transportation
- Packaging should be marked with product name, trade name, mass, supplier details, and a conformity statement with EN 16003
- Product should be stored dry, away from acids, and transportation must comply with local regulations, though calcium magnesium carbonate is not classified as dangerous goods
Applications
Calcium magnesium carbonate is widely used in the water treatment sector for:
Drinking Water Treatment
- Removal of carbon dioxide (CO₂)
- Adjustment of pH and increase in water hardness, crucial for corrosion control in distribution systems
- Used in granular or crushed form, typically in filtration applications
Secondary Effects
- Assists in filtering suspended solids and removing certain metals from water during treatment
Safe Usage
- Does not require special hazard labelling
- Safe handling procedures recommend keeping the product dry and removing spills mechanically
- The product is stable and non-combustible
The application dosage and particle size selection should be tailored to the specific treatment process and water quality goals.
