Overview

EN 16070:2014 - published by CEN - specifies requirements for natural zeolites used in the treatment of water intended for human consumption. The standard covers identification, commercial forms, physical, chemical and mineralogical properties, test methods, labelling, transportation and storage. The natural zeolite species explicitly covered are clinoptilolite, chabazite and phillipsite/analcime. EN 16070:2014 helps suppliers, test laboratories and water operators demonstrate product characteristics relevant to drinking water treatment.

Key Topics

• Scope & identification: Defines chemical name (crystalline hydrated aluminosilicate), synonyms and CAS/EINECS references for natural zeolites.
• Physical properties: Requirements for appearance (dry, free‑flowing granules), particle size distribution (d10/d50 or particle size ranges with oversize/undersize limits), and bulk loose density (specified ranges per zeolite type).
• Chemical & mineralogical properties: Sets minimum purity requirements and limits for common impurities; producers must notify users of any additional impurities or additives.
• Cation exchange capacity (CEC): Specifies a performance threshold - total CEC shall be not less than 1.2 mg NH4+ per g of zeolite - and explains ammonium-based testing as a quality standard.
• Test methods & sampling: References and methods for sampling, particle size analysis, bulk density, ignition loss (150 °C and 650 °C procedures), capacity testing and repeatability criteria.
• Handling, labelling & storage: Guidance on means of delivery, EU labelling, transport regulations, marking and safe storage/handling recommendations.

Applications

EN 16070:2014 is practical for any application where natural zeolite is considered for use in producing safe drinking water:

• Ion exchange and removal of cations (e.g., ammonium control) in municipal and decentralized water treatment
• Use as a granular filtration/support medium in treatment filters and adsorption beds
• Blending or specifying zeolite media for groundwater treatment, wellhead protection, or pre/post‑treatment stages The standard helps ensure consistent product quality, traceable testing and suitability assessment for potable water uses.

Who uses this standard

• Water utilities and treatment plant operators evaluating filtration media
• Manufacturers and suppliers of natural zeolite products
• Testing and certification laboratories performing EN 16070 test methods
• Consulting engineers and public health/regulatory authorities reviewing media specifications

Related Standards

Relevant normative references cited in EN 16070:2014:

• EN 12901 (Definitions for inorganic supporting and filtering materials)
• EN 12902 (Methods of test for inorganic supporting and filtering materials)
• EN ISO 3696 (Water for analytical laboratory use)
• EN ISO 14911 (Ion chromatography methods for common cations)

Using EN 16070:2014 supports consistent, verifiable selection and testing of natural zeolite media for safe, compliant drinking water treatment.
