Nitrifying bacteria medium circulating water culture biological filter material cross sponge ball

Crossed sponge balls are a high-quality material used in biological filtration or biological culture. It is made of polyurethane foam. The special process allows it to achieve a specific surface area of cubic meters/cubic meters. Such a structure is very conducive to the growth of bacteria. There is a criss-cross plastic frame on the outside for fixation. It can prevent the extrusion deformation that may occur when multiple layers of sponge balls are piled together.

Polyurethane material has good corrosion resistance and can last for more than ten years during the aging process. Therefore it can be used as a filler for biological filters in seawater circulating water treatment. The overall three-dimensional network structure allows it to better contact with water, allowing bacteria to fully react with substances in the water. It is also easy to backwash. When the bacterial film becomes too old, the aged bacterial film can be easily flushed away to maintain the vitality of the entire biofilter. The ultra-high specific surface area is what makes it unique from other biological filter materials.

Widely used in biological filtration links of various water treatments. Crossed sponge balls can be stacked in the biofilter. Add biological bacteria when the water flow rate, temperature, dissolved oxygen, and ammonia nitrogen concentration are all suitable. Biological bacteria will reproduce using sponge balls as carriers. Biological bacteria can convert certain chemicals in water into non-toxic substances. In order to achieve purified water quality and control the concentration of toxic substances in the water.
