Introduction:

When choosing a filter medium for drinking water applications, accreditation and certification are even more important to make sure the product is safe, effective, and meets stringent health and safety standards. Glass filter medium, such as AFM (Activated Filter Media), is also gaining popularity because of its excellent performance over traditional sand or any other material. However, what these meet regarding certification and safety standards should go a long way in your choice of the processes.

Importance of Accreditation and Certification in Choosing Glass Filter Media for Drinking Water:

1. Health and Safety Compliance:

   The glass media has to be certified safe for use in drinking water systems. This means that it must not leach harmful substances or chemicals into the water. Certifications such as NSF/ANSI 61 validate that the material meets rigorous health safety standards.

2. Performance Validation:

Accredited glass filter media is tested for critical parameters such as filtration efficiency, turbidity reduction, and microbial control. For example, a high-grade glass media like AFM ensures excellent filtration performance and self-sterilizing properties, thus having lower chances of biofouling.

3. Durability and Lifespan:

This ensures that the product is manufactured to very high standards of quality, thereby providing long-term durability without degradation or contamination even under heavy-duty usage in water treatment plants.

4. Environmental Compliance:

The majority of glass media products, such as AFM, are constructed from recycled glass, promoting environmental sustainability. Certifications ensure such claims are validated and follow environmental safety guidelines.

5. Global Recognition and Trust:

Glass media is recognized internationally and guarantees regional and international compliance with drinking water standards. Additionally, it is critical for municipalities, industrial use, and residential systems.

Certifications and Standards of Glass Media in Drinking Water

– NSF/ANSI 61 Certification:

Likewise, It ensures the glass media is non-toxic and safe for potable water systems that do not contain harmful elements that could contaminate the water.

– WRAS (Water Regulations Advisory Scheme):

 It ascertains that the product complies with UK water safety standards. Thus, it is used for drinking water applications.

ISO 9001 and ISO 14001:

ISO 9001 certifies the quality of the manufacturing process, while ISO 14001 ensures environmentally friendly practices.

EN 12902/12904:

These European standards specify the requirements for granular filter media used in drinking water treatment, including safety and performance.

Case Example: AFM (Activated Filter Media)

AFM is a premium glass filter media that exemplifies the importance of certification:

– NSF/ANSI 61 Certified: It guarantees safety for use in drinking water.

– Self-Sterilizing: Due to its engineered surface and catalytic properties, AFM inhibits bacterial growth, thus, it ensures microbiological safety.

– Long-lasting and environmentally friendly: Since it is made from recycled glass, it is an eco-friendly and long-lasting solution.

– Enhanced Filtration: This is certified to achieve higher turbidity reduction than that of sand, thus delivering cleaner and safer drinking water.

Key Reasons Why Accreditation and Certification are Critical to Glass Filter Media in Drinking Water

1. Health and Safety Assurance:

Drinking water standards require the media not to leach any harmful substances in the form of heavy metals, toxins, or even microplastics into the water. Therefore, certifications from NSF/ANSI 61* and WRAS assure compliance with tight health criteria for the media, ensuring its safety and reliability.

– In the case of glass media such as AFM, certification proves that its recycled glass components have been processed free of contamination, thereby the material non-toxic.

2. Filtration Efficiency:

The performance metrics of turbidity reduction, particulate removal, and microbial filtration of the accredited glass media are independently tested consequently, this ensures their effectiveness and reliability in water treatment.

– Certified products such as AFM have higher filtration efficiencies than sand because of their engineered surface and reduced tendency to clog pores.

3. Biosecurity and Microbial Control:

– Some glass media certifications include bacterial growth resistance or biofouling. However, AFM is certified as self-sterilizing with no bacterial colonization without any chemical additives.

4. Environmental Compliance: 

   – Recycled glass filter media aligns with sustainability goals. Hence, Certifications like ISO 14001 validate that the manufacturing process is eco-friendly and reduces environmental impact. 

5. Durability and Longevity: 

   – Accredited products are tested for durability under long-term use. Certified glass media like AFM is resistant to degradation, ensuring a longer service life compared to traditional sand or unprocessed media.

6. Global and Regional Market Compliance:

   Accreditation guarantees that the product will be in compliance with the both international (e.g. NSF, ISO) and regional (e.g. WRAS, EN) regulations, so appropriate for the diverse markets.

Critical Certifications and Standards for Glass Filter Media

1. NSF/ANSI 61

– An international reference point for the safety of drinking water supplies. Furthermore, it guarantees that the product will not give off deleterious or toxic substances into the potable water supply. 

  – Certified glass media by this standard is safe for residential, commercial, and municipal potable water systems.

2. WRAS (Water Regulations Advisory Scheme)

  – Meets the UK regulations regarding water safety.

– Concentrates on ensuring the product will not harm the water quality.

3. ISO Certifications:

ISO 9001 : It will assure that the manufacturing process is of quality.

14001: It will prove that the manufacturing process complies with environmental management standards.

4. EN 12902 and EN 12904 European Standards:

– Requirement on granular filter media for drinking water. Specifically, EN 12904 addresses the physical and chemical properties of glass media.

5. DVGW:  The association of German Technical and Scientific Association for Gas and Water, therefore ensures that it meets the regulations of the German water treatment.
