Everyone knows that basalt stone is generally used in the construction industry, but many people may not know that basalt stone can also be used as a biological filler, mainly because of its excellent performance. Next, let's learn about the use of basalt stone as a biological filler.
When basalt is used as a biological filler, it has many high-quality characteristics, which are inseparable from the characteristics of basalt. Basalt stone biological filler is generally used in wetlands, and its advantages in use are mainly manifested in the following aspects: good permeability, large surface area, which is conducive to microbial fixation and biofilm formation.
The use of basalt stone plays an important role in the nutrient requirements of microorganisms, which can maintain good nutrient retention and facilitate the reproduction of microorganisms in wetlands. Basalt stone bio fillers do not discolor after water immersion and have a certain mechanical strength. The surface area provided in terms of space, volume, and morphology can meet the living environment of microorganisms.

In terms of biological stability, these fillers have inert properties to resist biological corrosion of the fillers. In addition, its chemical properties are relatively stable and it is inert to chemical reactions that occur in the environment, thus exhibiting good corrosion resistance. Its use is not affected by high temperatures, so it also has the advantage of thermodynamic stability.
The use of biological fillers also needs to be based on the functional requirements of artificial wetlands, and we can choose substrates with certain chemical components. Because this type of matrix contains a significant amount of natural substances that can be recycled and reused. Materials containing special components artificially synthesized from solid waste can be recycled and reused in different proportions of mixed materials. The advantages of biological fillers include their hydrophilicity, hydrophobicity, and surface electronegativity. Hydrophilic microorganisms are easy to adhere to the surface of hydrophilic fillers, while hydrophobic fillers facilitate the fixation of hydrophobic microorganisms on their surface.
Basalt stone, as a biological filler, can achieve recyclability and save costs to a certain extent. If you want to know more about basalt stone, you can continue to follow us.
