Overview
prEN 1018:2024 is a European standard developed by CEN/TC 164 that specifies the requirements for calcium carbonate used in the treatment of water intended for human consumption. This standard updates and supersedes EN 1018:2021, enhancing transportation, labelling, composition, and impurity criteria relevant to calcium carbonate products. It provides a comprehensive framework including physical and chemical properties, purity criteria, test methods, and practical guidelines for handling calcium carbonate in water treatment applications.
Key Topics
- Scope: Applies to calcium carbonate used as a chemical agent for water treatment to ensure safety and suitability in potable water systems.
- Characteristics: Defines calcium carbonate as limestone or chemically produced CaCO3, describing its physical form (crushed, granular, slurry), appearance (white or grey), density (~2.71 g/cm³), solubility (0.014 g/L at 10 °C), and weak alkalinity.
- Purity criteria: Establishes minimum purity levels and limits for impurities and by-products, classifying products as non-porous or porous calcium carbonate with specific compositional thresholds.
- Chemical parameters: Sets maximum allowable concentrations for trace elements such as antimony, arsenic, cadmium, chromium, lead, mercury, nickel, and selenium to minimize health risks.
- Test methods: Specifies standardized protocols for sampling and analyzing calcium carbonate consistent with EN 12485 and related ISO standards (ISO 3165, ISO 6206, ISO 9277).
- Labelling and transport: Details handling, packaging, and labelling requirements aligned with EU regulations, emphasizing compatibility and safety in storage and transport without hazardous classification.
Applications
Calcium carbonate plays a critical role in water treatment processes aimed at improving water quality for human consumption. Its practical applications include:
- pH adjustment: Due to its weak alkalinity, calcium carbonate helps neutralize acidic water, preventing corrosion of plumbing and infrastructure.
- Softening: It aids in reducing water hardness by precipitating calcium and magnesium ions, enhancing water taste and usability.
- Corrosion control: Maintaining water pH stability protects distribution systems against material degradation.
- Dose flexibility: Available in various particle sizes and forms (powder, granules, slurry), facilitating precise dosing suited to differing water treatment requirements.
- Safety compliance: Adherence to purity and impurity thresholds ensures no adverse impact on potable water quality, aligning with national and EU drinking water regulations.
Related Standards
- EN 12485: Specifies test methods for chemicals used in potable water treatment, including calcium carbonate analysis.
- ISO 3165 and ISO 6206: Provide guidelines for safe sampling and terminology relevant to chemical products for industrial and water treatment use.
- ISO 9277: Governs determination of specific surface area of solids by gas adsorption, applicable to assessing calcium carbonate properties.
- EU Chemicals Regulation: While calcium carbonate is not classified as a dangerous good, compliance with current EU labelling regulations ensures safe marketing and transportation.
Keywords: calcium carbonate standard, water treatment chemicals, potable water treatment, calcium carbonate purity, water treatment regulation, CEN water standards, calcium carbonate test methods, water treatment safety, EU drinking water standards, calcium carbonate impurities, water pH control, calcium carbonate applications in water treatment.
