4.It has no radiation but has far infrared magnetic wave.
|Red Lava Stone Chemical composition||Physical Properties|
|MgO||2.46||Cylinder pressure strength||1.218Mpa|

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.
