Modified MBBR Biofiller

Bio-filler specifications and performance

The bio-affinity hydrophilic and magnetized polymer filler can increase the hydrophilicity (in terms of water absorption) by 2~3 times, and the surface water contact angle can be reduced by 15°~30°; The bio-film forming time is reduced by 3~6 days;After bio-film forming stabilized, the COD removal rate is 10~30% higher than that of the other polymer filler.

MBBR filler specifications and models:

∮25mm, length 10~12mm, thickness 0.6~0.8mm, intermediate circle 0.4~0.5mm, outer surface with teeth, three rounds from center to outer circle, roundness ≤20%, tooth depth ≮1mm.

Technical highlights and innovations:

1, Introduced a biological hydrophilic polymer material which can increase the adsorption probability of pollutants. Since a large amount of hydrophilic groups -OH (hydroxyl groups) exist on the surface of the material, they can be hydrogen-bonded with water molecules to improve hydrophilic of the filler,which increases the chance of contact of the sewage with the biofilm attached to the filler.

2,Introduced biologically active substances.This substance not only provides a suitable source of nutrients for the microorganisms, but also improves the hydrophilicity of the filler,and is beneficial for microbial growth, speed up the biofilm forming start and improve sewage treatment efficiency.

3,Introduced barium ferrite magnetic powder containing rare metals.The magnetically processed filler forms a microscopic strong magnetic field and a macroscopic weak magnetic field. Through the action of the magnetic field, the osmotic pressure of water and the concentration of dissolved oxygen in water can be increased, which is beneficial to the diffusion of substances and the absorption and utilization of oxygen by microorganisms. At the same time, the enzyme oxidation reaction and free radical reaction of the system are accelerated; It induces the enzyme activity and enzyme synthesis of microorganisms, promotes the growth of microbial growth membranes and metabolism, and also improves the permeability of microbial cell membranes. Improve the activity of microorganisms and biological enzymes, strengthen the adsorption of degrading bacteria on the surface of the filler, and thereby improve the bio-film forming speed in the sewage treatment and the degradation rate of the sewage.

4, The introduction of active calcium in biofiller.It significantly modified the mechanical properties of the polymer filler, especially impact strength and toughness;

5, In order to further improve the dispersibility of the additive and prevent agglomeration, the active calcium and barium ferrite magnetic powders are chemically coated and modified, and then mixed and processed with other components. The modified inorganic powder material is evenly distributed inside and on the surface of the filler, so that the product performance is more stable.
