1. The pores inside the volcanic rock are densely distributed, and the pores are the prerequisite for parasitic nitrifying bacteria. The ultra-microporous filtration is smooth and the oxygen content is increased.
2. The specific surface area of volcanic rock is large, which is conducive to the growth and reproduction of microorganisms on its surface and the formation of biofilm. Maintain a high microbial load.
3. The manufacturer sells volcanic stone directly, with good quality and favorable price, and there are two kinds of packaging, bagged and bulk.
Volcanic rock biological filter material: the surface is rough and microporous, and the specific surface area is large. These characteristics are especially suitable for the growth and reproduction of microorganisms on the surface to form biofilms. Maintaining a large amount of microorganisms is conducive to the mass transfer process of oxygen and nutrients required in the process of microbial metabolism and waste generated by metabolism.
Not only can it treat municipal sewage, as well as biochemical organic industrial wastewater, domestic drainage, slightly polluted source water, etc., it can also replace quartz sand, activated carbon, anthracite, etc. The tail water after the secondary treatment process of the plant is subjected to advanced treatment, and the treated effluent can be reused as reclaimed water after reaching the reuse water standard. The volcanic rock biological filter material is non-pointy, with an average internal and external porosity of about 40%. It has low resistance to water flow during use. Compared with similar filter materials, it requires less filter material and saves energy consumption.
