Volcanic rock (commonly known as pumice stone or porous basalt) is a functional eco-friendly materials, is after the volcanic eruption, volcanic glass, minerals and air bubbles to form a very valuable form of porous stone, volcanic rock containing sodium, magnesium, aluminum, silicon, calcium, , titanium, manganese, iron, nickel, cobalt and molybdenum and many other kinds of minerals and trace elements, non-magnetic radiation with far-infrared, in the ruthless, after a volcanic eruption, only after ten thousand years, mankind has gradually found it of a society. My company has expanded its applications to the construction, irrigation, grinding, filter, charcoal barbecue, garden landscaping, soilless cultivation, ornamental items and other areas, in all walks of life play an irreplaceable role in!

Volcanic rock (basalt) characteristics of

First, the physical characteristics of volcanic rocks of biological filter:

1, appearance shape: no sharp granular on the flow resistance is small, easy to plug, cloth, water, gas uniform cloth; surface roughness, hanging film speed, anti-microbial film is not easy when you wash off.

2, porosity: porous volcanic rock is a natural cellular is Zoogloea is a good growing environment.

3, mechanical strength: quality control by the state sector 5.08Mpa, in practice proved to be able to endure different degrees of hydraulic shearing, long life is far from other filter.

4, density: density of medium, anti-washing materials be easily suspended and does not run, you can save energy.
