1. volcanic rock biofilter is corrosion-resistant, inert, and does not participate in biochemical reaction of biofilm in the environment.


2. Surface electricity and hydrophilicity: the surface of volcanic rock biofilter has positive charge, which is conducive to the growth of microorganisms, strong hydrophilicity, and the amount of attached biofilm is large and fast.


3. The influence on the activity of biofilm: as the carrier of biofilm, volcanic rock biofilter is harmless and has no inhibitory effect on the fixed microorganism.
