Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • When selecting polyurethane sponge fillers for supply, it is recommended that enterprises match specific application requirements based on key technical parameters such as density, pore size, and rebound rate, such as biological carriers in wastewater treatment or buffering materials in industrial equipment.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information. These indicators help screen stable and reliable partners.
  • Polyurethane sponge packing is commonly used for gas distribution and filtration in waste gas treatment towers. When purchasing, attention should be paid to its chemical corrosion resistance and structural stability under long-term use.
  • For application scenarios that require high porosity, such as aquaculture biofilters, it is recommended to verify the specific surface area and membrane hanging effect of the packing material based on the measured data provided by the supplier.

Knowledge Base

Q

  1. Rich porosity, large specific surface area, conducive to the proliferation and growth of microbial communities on its surface, and occupying a small area. 2. Combining physical adsorption with positive and negative charge attraction, it has good hydrophilicity and high biological activity, making it a highly effective biological filler with fast membrane formation rate; 3. The filling holes are interconnected, with large pores and few dead zones, making it less likely to cause blockage.

Q

Hydrophilic polyurethane biological sponge filler is formed by dual explosion of oxygen and hydrogen, with evenly interconnected pores, achieving a comprehensive bacterial carrier for the entire biological sponge filler. Due to the special structure of the biological carrier, the breakthrough point of polyurethane sponge filler is to achieve nitrosation reaction on the outer surface of a single biological carrier in the aeration tank and denitrification of nitrite inside, which not only includes
