Enhancement of fi ltering effi ciency
AFM
®
activated fi lter media
AFM is direct substitute for fi lter sand. It doubles effi ciency of the existing
fi ltration system. AFM
®
is resistant to biological pollution and formation of
so-called bio-fi lm.
ZPM
®
coagulation mixer
ZPM increases eff ects of coagulation and fl occulation for transition of
smaller dissolved solids (turbidity) to larger particles that can be removed by
fi ltering.
