NO RETURNS / NO EXCHANGES (4 BAG MINIMUM PURCHASE OF ANY GRADE AFM)

This is the AFM GRADE 3 (Medium) which is usually used by pool owners in their sand filters as the first part of the 3-Stage Activated Glass Filter System.  It is installed on top of the laterals inside the sand filter body and under grade 2 and grade 1 media.


ZeroChlor recommends AFM Filters anytime a pool is upgraded to the ZeroChlor Pool System.  Consider adding on AFM during checkout!  If it's not AFM its not Activated.  Activation of the glass media is the most important part!


AFM is an Activated Filter Media, manufactured and activated by Dryden Aqua under ISO procedures to have a high negative zeta potential and catalytic self sterilizing properties.


AFM is manufactured from reprocessed glass, but it is not a basic crushed glass filter media. We have experience with lots of glass media brands but none of the brands we have tried even come close to the performance and longevity of AFM. AFM is a highly processed product which has been tested by independent UK Government laboratories and the water industry and has been certified safe for all water filtration applications. Filter sand has by-passed the regulations because it was in use before the regulations were in place. However man made filtration products are not exempt, and AFM is the only filtration media that is in compliance with the regulations and is safe to use for applications such as drinking water, swimming pools and aquaria. A basic crushed glass product does not have the surface active properties, there will be a hydraulic lenses effect which leads to channeling, there are also serious health implications for the public and contractors from using a basic crushed glass product. Dryden Aqua have completed a 1.2 million Euro Research Project in co-operation with the European Commission under the Life Environment initiative to solve these problems. For information

What is AFM?

AFM® is an activated filtration media manufactured by Dryden Aqua. In addition to the product applications and process technology have been developed by Dryden Aqua. AFM is engineered to have surface active properties of adsorption and catalysis as well as acting as a mechanical filtration media. AFM is a great deal more than a recycled glass filter media.​

 

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® 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 become self-sterilizing and to acquire superior adsorption properties.


Self sterilizing surface: AFM is 100% bio-resistant, prevents channeling and the biological conversion from urea to ammonia in the filter bed responsible for the toxic chlorine smells (trichloramines).


Superior adsorption properties: : The surface area of AFM® is strongly increased and becomes hydrophobic (water-repellent) to filter particles down to 1 micron and to remove about 50% more organic substances from the water than sand and other glass filter media, thus reducing the formation of harmful THMs including chloroform by up to 50%.

Performance and Benefits

1. Up to 80% better performance than sand
2. Self sterilizing does not become biofouled
3. Almost eliminate trichloramine and THM`s
4. Effective barrier against cryptosporidium
5. Reduce Legionella and MRSA levels
6. Excellent for iron and manganese removal
7. Lowers DOC ( dissolved organic carbon)
8. Arsenic removal when combined with NoPhos
9. Can remove some toxic prescribed substances
10. 70% saving of back-wash water
11. Reduce pumping costs ( lower delta P)
12. 100% environmentally sustainable
13. Filter performance is stable and predictable
14. Life Cycle cost savings
