AFM® grade 0 Performance.
All the data for AFM® has been established without the application of coagulants or flocculants. It is important to note that
AFM® grade 0 can be used as an effective Cryptosporidium oocysts barrier at water flows of 2m/hr with a 900mm bed depth.
When AFM® is combined with coagulation and flocculation using PAC (polyaluminium chloride) or Polyamide cationic
flocculants, the performance and ability to remove cryptosporidium oocysts at 5 microns and sub 1 micron is greatly
enhanced. The performance data presented is without the application of flocculants.
