Product Detail
AFM (Activated Filter Media) is a bio-resistant filtration material made exclusively out of green and brown glass. That means:-
- No clusters or channeling and therefore continuous good filtration performance over many years
- Less problems with Legionella, Pseudomonas or cryptosporidium
Less Chlorine smell, because 50% less Trichloramine and 50% less THM’s (Trihalogenmethane) are created
What is AFM?
AFM Activated Filter Media is a direct replacement for sand, doubling the performance of sand filters without the need of additional investments in infrastructure. AFM resists biofouling, biocoagulation and transient wormhole channeling of unfiltered water and never needs to be recharged or replaced. AFM is a highly engineered product manufactured from a specific glass type, processed to obtain the optimum particle size and shape. It is then exposed to a 3-step activation process to increase its surface area by up to 300 times for superior mechanical and electro-static filtration performance.
At 20m/hr flow rate, AFM grade 1 filters 95% of particles down to 1 micron. AFM grade 2 filters 95% of particles down to 4 microns. Sand filters 95% of particles down to 20 microns. Glass media filters 95% of particles down to 25 microns.
After 6-12 months, biofilm in sand has developed to a degree where the grains stick together forming clumps and channelling of the filter bed. This reduces filter performance and allows some unfiltered water to reach the bathers. Filtration performance with AFM is predictable, reliable and remains stable over many years. There is no possibility of unfiltered water reaching the pool.
Sand filters can develop into a breeding ground for pathogens such as legionella and pseudomonas. Periodically bacteria flocs will break through the filter. AFM prevents the growth of these pathogens. Your pool water is therefore much safer.
Pool users sweat and urinate in the pool water. They consist of 80% of urea. Bacteria in the biofilm convert this urea into ammonia which then reacts with chlorine to form inorganic chloramines. Trichloramine is very volatile and is responsible for the unpleasant chlorine smell. It is also a severe health hazard causing skin, eye and lung irritation. With AFM there is no biological conversion from urea to ammonia inside your filter- no biofilm; no trichloramine; no chlorine smell!
AFM benefits at a glance
- more than doubles the performance of an existing filtration system
- is not subject to biodynamic instability and will never allow untreated water to pass
- substantially lowers chlorine oxidation demand
- lowers backwash water demand by an average of 50%
- is expected to last for the life of the filtration system
- provides quick return on investment
Excellent performance of AFM in comparison with quartz sand and other glass filter media
AFM comes with important certifications such as NSF 50 (swimming pools) and 61 (drinking water), HACCP, UK DWI and others. AFM has been independently tested by IFTS Institut de la Filtration et des Techniques Séparatives in France in 2014. Its superior performance over quartz sand and other glass filter media was confirmed and and is documented in the the 2014 IFTS Report. AFM more than doubles the performance of a quartz sand filter and it performs multiple times better than all other glass filter media tested.
What makes AFM so effective?
1. Clean, carefully selected glass- AFM is only made from pure green and brown glass which have the necessary metal oxides to help make AFM self-sterilising.
2. Ideal hydraulic properties- The raw material is ground into the optimal grain size and shape that is crucial for the outstanding hydraulic characteristics of AFM. No dangerous glass splinters are allowed to be present in the filter material. Our manufacturing process is ISO certified.
3. Activation process- The AFM activation process creates a mesoporous structure with a huge catalytic surface area. Sand has a surface area of 3,000 m2 per m3 but AFM has a surface area up to 300 times greater for adsorption and catalytic reactions. Hydroxyl groups on the surface give AFM a strong negative charge, known as the zeta potential, that attracts heavy metals and organic molecules. In the presence of small amounts of oxygen or oxidising agents, the catalytic surface generates free radicals that make AFM self-sterilising.
Suitable for use in all swimming pool sand filters.
AFM is better than glass filter media (PGFM). PGFM does not undergo the patented activation process and it is manufactured from mixed glass - the white glass is not sorted out. Nevertheless, PGFM is a better filter media than sand because it biofouls less, but it is not bioresistant like AFM.
For sand filters (below 100cm/39in diameter), use 70% of AFM grade 1 (0.4-1.0mm) and 30% of AFM grade 2 (1.0-2.0mm).
