1. The densely distributed pores of volcanic rocks are the prerequisite for parasitic nitrifying bacteria, and the special honeycomb network structure makes the filtration and permeation smoother.
2. Natural red volcanic rock, without pigments and additives, the color is pure and natural.
3. Red volcanic rock has high strength, acid and alkali resistance, corrosion resistance and no pollution.
Physical properties of volcanic rock Appearance shape: no sharp grain, small resistance to water flow, not easy to clog, uniform water and gas distribution, rough surface, fast film formation, and microbial film is not easy to fall off when repeated washing. Porosity: Volcanic rock is a natural honeycomb porous, which is the best growth environment for fungal micelles. Mechanical strength: It is 5.08Mpa by the national quality inspection department. Practice has proved that it can withstand hydraulic shearing of different strengths, and its service life is much longer than other filter materials. Density: Moderate density, easy to suspend and not run out during backwashing, saving energy and reducing consumption. Biochemical stability: The volcanic rock biological filter material is corrosion-resistant, inert, and does not participate in the biochemical reaction of the biofilm in the environment. Surface electricity and hydrophilicity: The surface of the volcanic rock biological filter material has a positive charge, which is conducive to the growth of microorganisms. With strong hydrophilicity, the amount of attached biofilm is large and fast. In terms of impact on biofilm activity: As a biofilm carrier, volcanic rock biological filter material is harmless and has no inhibitory effect on the fixed microorganisms, and practice has proved that it does not affect the activity of microorganisms. Used to lay garden landscape can adjust the temperature and humidity of the soil. Reduces soil compaction and reduces manual maintenance.
