Activated Filter Media
AFM® comes with important certifications such as NSF/ANSI 50, NSF/ANSI/CAN 61 by WQA for swimming pools and drinking water applications, HACCP, UK DWI and others. AFM® has been independently tested by IFTS Institute de la Filtration et des Techniques Séparatives in France in 2014 and its superior performance over quartz sand and other glass filter media was confirmed and and is documented in the the 2014 IFTS Report available below. AFM® more than doubles the performance of a quartz sand filter and it performs multiple times better than all other glass filter media tested.
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, crucial for the outstanding hydraulic properties 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 for greater 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.
