Product Overview
Hydrophilic polyurethane bio-filler is a new type of bio-filler synthesized from high polymer materials. It combines large pores and micropores in polyurethane fillers, where large pores maintain good contact conditions for gas, liquid, and solid, and micropores are used for immobilizing microorganisms. These micropores contain hydrophilic active groups such as amino, carboxyl, and epoxy groups, which can form ionic or covalent bonds with certain active groups in the microbial peptide chains, thereby immobilizing microorganisms and bioenzymes on the carrier. The density of the bio-filler after immobilizing microorganisms is close to that of water, with a high microbial load, large volumetric load, and a large specific surface area. Due to the structural characteristics of polyurethane fillers, they allow for mixing and contact exchange of wastewater, air, and biofilms. Biofilms can not only settle in large quantities within the microbial carriers while maintaining good activity and porosity variability but also, during operation, the gas is continuously chopped into smaller bubbles by the蠕动状态的 microbial fillers driven by the three-dimensional flow of wastewater, increasing oxygen utilization and reducing aeration volume. Therefore, it has strong bubble-cutting ability, high spatial volume utilization, and no dead zones, making it an updated and upgraded product in the current bio-filler market.
Product Features
1) Polyurethane fillers have a large specific surface area, allowing microbial populations to reproduce and grow on their surface, forming a highly active biofilm. This prevents the loss of slow-reproducing, low-yield microbial populations, such as nitrifying bacteria.
2) Enhance the efficiency of the biochemical system and the stability of the biochemical pond.
3) Reduce the toxic effects on microbial communities from non-degradable substances and toxic substances.
4) Enhanced system tolerance to load, toxic inhibitory substance impact, pH and temperature fluctuations; Reduced the generation of residual sludge.
5) Achieve simultaneous nitrification and denitrification.
Application Scope
This media is suitable for various types of structures in submerged biofilter systems used in contact oxidation methods, as well as for general bio-tower filters with spray irrigation, effectively distributing air and water uniformly. This media exhibits distinct effects in the biological treatment of various organic chemical wastewater, domestic wastewater, and urban sewage, as well as in micro-pollution pretreatment and denitrification technologies. It is applicable to wastewater treatment projects involving nitrogen and phosphorus removal from high-concentration organic wastewater, various industrial wastewater, refining wastewater, daily chemical wastewater, pharmaceutical wastewater, biofilters, desulfurization, deodorization, and urban domestic wastewater.
