The biological filler produced by our company is a specially
selected polymeric plastic biological filler, which is designed
according to the scientific idea and processed by a unique process.
Its specific gravity is slightly lighter than that of water (0.97).
When the biofilm grows, its specific gravity is similar to that of
water, and it is suspended in the wastewater. The
filler has a huge area, with a surface area of 5002/m3. Although
the microorganism on the biological filler is in the mode of
attachment and growth, it is suspended in the wastewater like the
micelle in the activated sludge process with the flow of the
biological filler. Under certain conditions, the maximum volumetric
load of the filler can reach 35kgeod/2d. Based on the unique design
of biological packing, the relative residence time of air in
wastewater is prolonged, the oxygen charging efficiency is
improved, and the energy consumption is reduced, which has direct
economic benefits.
