Product Description
Red Lava Stone Scoria Rock
China Red Lava Stone
1.Lava rock is a functional kind of environmental protection material.
2.It is a kind of precious and porous basalt and formed by volcanic glass ,mineral and air bubble in the process of volcanic eruption.
3.It contains dozens of minerals and microelements, such as sodium, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt and molybdenum and so on.
4.It has no radiation but has far infrared magnetic wave.

Biochemical stability:
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.
