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, with large pores maintaining good contact conditions for gas, liquid, and solid, and micropores 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 biological enzymes on the carrier. The density of the bio-filler after immobilizing microorganisms is close to that of water, with a high microbial load, high volumetric load, and a large specific surface area. Due to its structural characteristics, polyurethane fillers can facilitate mixing and contact exchange between wastewater, air, and biofilms. Biofilms not only settle in large quantities within the microbial carriers, maintaining good activity and porosity variability, but also, during operation, gases are continuously sheared 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 requirements. Therefore, it boasts strong bubble-cutting capabilities, high space volume utilization, and no dead zones, making it an updated and replaced product in the current bio-filler market.
Product Features
1) Polyurethane fillers have a large specific surface area, allowing microorganisms to thrive and reproduce on their surface, forming a highly active biofilm. This prevents the loss of slow-reproducing, low-yielding microorganisms, such as nitrifying bacteria.
2) Enhance the efficiency of the biochemical system and the stability of the biochemical pond.
3) Reduce the toxic effects of non-biodegradable and toxic substances on microbial populations.
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 packing is suitable for various types of structures used in submerged biofilter oxidation ponds for contact oxidation, as well as for general bio-tower filters with sprinkling water systems, where it functions to evenly distribute air and water flow. The packing demonstrates distinct effects in the biological treatment of various organic chemical wastewater, domestic wastewater, and urban sewage, as well as in the pre-treatment of micro-polluted water and nitrogen removal technologies, compared to other packings. It is applicable to wastewater treatment projects involving nitrogen and phosphorus removal from high-concentration organic wastewater, various industrial wastewater, oil refining wastewater, daily chemical wastewater, pharmaceutical wastewater, biological filters, desulfurization, deodorization, and urban domestic wastewater.
