Product Description

Lgel Ball , also known as Hedgehog Ball or Sea Urchin Ball, is a spherical packing material with a unique needle-like shape. Its name "Igel" comes from German, meaning "hedgehog," vividly describing its hedgehog-like appearance covered with tiny columnar protrusions. This unique design gives it extremely special performance characteristics among random packing materials.

The development of Lgel Ball is closely related to the rise of biofiltration technology. While traditional packing materials have a large specific surface area, their surfaces are mostly continuous smooth curves, limiting biofilm adhesion. The designers of Lgel Ball drew inspiration from hedgehogs, sea urchins, and other organisms in nature, creatively designing the packing surface with a dense structure of needle-like protrusions, significantly increasing the effective surface area and adhesion strength for microorganisms.

The design philosophy of Lgel Ball can be summarized in eight words: surface is king, needle-like protrusions win. It does not pursue the absolute maximization of specific surface area, but rather the maximization of effective specific surface area—that is, the surface area that can actually be utilized by microorganisms and contacted by gas and liquid. Its unique needle-like structure makes each "thorn" an independent gas-liquid contact point and biofilm attachment point, which greatly improves the utilization efficiency of the packing material.

Product Feature

1. Unique Needle-like Structure, Large Specific Surface Area
Lgel Balls feature densely distributed tiny columnar protrusions ("spines") on their surface, creating a vast effective surface area within the limited spherical surface. Compared to spherical packing materials with smooth surfaces, Lgel Balls offer several times the increase in specific surface area. Simultaneously, the tiny spaces formed between the spines provide an ideal habitat for microorganisms.
2. Strong Biofilm Adhesion and Rapid Biofilm Formation
The needle-like structure of Lgel Balls results in a high surface roughness, making it extremely easy for microorganisms to attach and grow. Compared to traditional packing materials, Lgel Balls exhibit faster biofilm formation, more uniform biofilm thickness, and larger biomass. This characteristic makes them outstanding in biological treatment processes such as biofilters and MBBRs.
3. Lightweight and Floating Operation
Made of plastic, Lgel Balls typically have a density less than water (approximately 0.96–0.98 g/cm³), allowing them to float naturally in water. This characteristic allows it to operate in processes such as MBBR (Moving Bed Biofilm Reactor) without requiring additional fluidization power; aeration alone is sufficient to achieve full-tank fluidization of the packing material, resulting in low energy consumption and stable operation.
4. Low Water Resistance and Excellent Aeration
The open, needle-like structure of the Lgel Ball minimizes water resistance, allowing for smooth water flow and preventing clogging. Simultaneously, the spiky structure effectively cuts and disperses air bubbles, significantly improving oxygen transfer efficiency and increasing dissolved oxygen content in the water.
5. Corrosion Resistance and Long Service Life
Made of corrosion-resistant plastics such as polypropylene (PP) and polyethylene (PE), the Lgel Ball can withstand the erosion of most acids, alkalis, and organic solvents. Under normal operating conditions, its service life can reach over 10 years.
