Discover the unique 100% bio-resistant and world's best performing filtration media

afm®activated filter media

AFM® Activated Filter Media is a direct replacement for sand, doubling the performance of sandfilters without the need of additional investments in infrastructure. AFM® resists biofouling, biocoagulation and transient wormhole channeling of unfiltered water and outlasts all other filter media.

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 acquire superior mechanical & electro-static filtration performance.

unique benefits

Fully prevents bacterial growth, biocoagulation and channeling in the filter bed
Provides exceptional water clarity filtering particles down to 1 micron
Delivers stable filtration performance and outlasts all other filter media
Certified for pools (NSF 50) potable water use (NSF 61) food & drinks markets (HCAAP)
Prevents the formation of harmful disinfection byproducts (THMs, NCl3)
Significantly lowers chlorine oxidation demand
Attracts and removes heavy metals, organic matters and microplastics
Offers substantial water and energy savings thanks to shorter and slower backwashes

The FlowVis DN65 High Flow will be available from September 2019. This new model (ref 90026) has been developped by Dryden Aqua and features the perfect flow range (7 to 43 m3/h) to control backwash flowrate on DN65 applications. We remain at your disposal for any further information.

AFM activated filer media provides the citizens of Chennai, Pune and Bangalore with over 100 million litres of water per day, and this is set to double every year. Ground water and most surface water sources in India are grossly contaminated with plastic, sewage, industrial waste water, arsenic and fluoride. RO membranes have now been banned below 500mg/l TDS because they waste too much water. However, RO membranes can not treat most of the water because it is too grossly contaminated. Sand filter probably provide 98% of all drinking water but they are all subject to serious wormhole channelling, which allows plastic and contaminated water to enter the network. AFM can treat the water using pressure filters and RGF sand filters for rural and peri-urban water treatment.
