WHAT IS AFM® ng?
The result of 35 years of research and development, AFM® ng (Activated Filter Media) is the sand substitute that can be installed in any type of sand filter without modification.
Made from green and brown glass, AFM® ng has undergone a unique activation process that makes it self-sterilizing and provides increased mechanical and electrostatic filtration performance.
SELF-STERILIZING SURFACE: Resistant to bacterial growth.
ENLARGED CONTACT SURFACE: Mesoporous structure, for superior filtration performance.
CHARGED SURFACE: For the adsorption of the finest particles and organic matter.
- Healthier water: Prevents the transmission of pathogens (e.g. Cryptosporidium)
- The clearest water: It offers a stable filtration ratio of 1 micron.
- Healthier air: Prevents the formation of toxic byproducts and chlorine odor.
- Lowest operating costs: Savings on washing water and chemicals.
- The most sustainable filtration: Longer lasting than all other filter media
AFM® ng, THE HIGHEST PERFORMANCE FILTER MEDIA
Thanks to its large hydrophobic area and mesoporous structure, AFM®ng can filter much finer particles (1 micron) and 50% more organic substances than sand.
Why is activation so important? Because it significantly reduces chlorine consumption and guarantees crystal-clear water and the best air quality.
AFM® ng offers the finest filtration. Filters with AFM® filter much more than quartz or glass sand.
The renowned independent European filtration laboratory IFTS (Institut de Filtration et des Techniques Separatives) tested AFM®ng in October 2019 alongside other silica sand and glass media. The tests were carried out with the filter media fresh and without any biofilm, at a filtration speed of 20 m/h without the addition of any flocculant. The results showed that AFM®ng was the only one capable of filtering 95% of particles larger than 1 micron.
How should AFM® ng be used?
• The AFM loading on a filter is 15% less than what would be required for silica sand. This must be taken into account when calculating the AFM loading.
1 21kg bag of AFM = 1 25kg bag of sand (the volume is the same).
• There are three degrees:
The AFM® ng is the only medium that complies with ISO 9001-2008, Regulation 31 of the United Kingdom, UNE EN12902 and EN12904, and TÜV Certification of Germany. It has also received numerous awards, including those from the Barcelona Swimming Pool Show 2009, Smagua 2010, and Golden Wave International 2011.
