Biological filter material water treatment filter medium volcanic rock constructed wetland filter material

Volcanic rock biofilter has the following characteristics:

1. Porous structure: volcanic rock biofilter has a rich micropore and mesopore structure, which provides a good environment for the adhesion and growth of microorganisms, which is conducive to the formation of biofilm and the reproduction of microorganisms.

2. High specific surface area: The specific surface area of the volcanic rock biofilter is larger, which means that more microorganisms can be attached to its surface, thereby improving the treatment efficiency of the biofilter.

3. Good mechanical strength: volcanic rock biofilter has good mechanical strength, is not easy to break, and has a long service life.

4. Chemical stability: The chemical stability of volcanic rock biofilter is good, it is not easy to dissolve, and will not have a negative impact on water quality.

5. Good permeability: The permeability of volcanic rock biofilter is good, which is conducive to the transmission of oxygen and nutrients, and provides a good growth environment for microorganisms.

Volcanic biofilters are generally easy to install and maintain, and have a long service life. By adding volcanic rock biofilters, you can improve the ecosystem stability of the aquarium, reduce the risk of water quality fluctuations, and contribute to the healthy growth of fish and other aquatic organisms. In addition, the volcanic rock biofilter also has the characteristics of strong structure, not easy to decompose and non-toxic and harmless, which is an ideal biofilter medium.
