Key Points about AFM®
Technical key points

AFM® can double the performance of a sand filter, up to 100 times better at removing sub-5 micron particles
AFM® Grade 1 is verified to achieve log 3 reduction (1000 times) down to 4 microns with no coagulation or
flocculation
Stable and predictable performance, AFM® is not subject to biodynamic instability and will never allow
untreated water to pass through to the product water.
No biofouling means greatly reduced Legionella risk from the filter
Product water will have at least 50% lower chlorine oxidation demand than an equivalent sand filter, so lower
concentration of disinfection by products including THMs
AFM® is expected to last for the life of the filtration systems.

Quote from Scottish Water
Scottish Water tested AFM®, the results demonstrated significant performance advantage over sand in
relation to suspended solids/iron removal and process efficiencies. I can also confirm that Scottish Water has
been using AFM® for targeted effluent treatment for some 14 years with considerable success in the removal
of solids and BOD reduction. Mark Haffey , R&D Technical Leader, Technology & Innovation Scottish Water
