1.Product introduction of foam filter beads: |
Foam filter beads are white spherical filter materials made of imported polystyrene resin particles that are foamed twice at high temperature, and the degree of foaming is more than 40 times that of raw particles. |
2.Features of foam filter beads |
This product has the advantages of light weight, large specific surface area, strong adsorption capacity, non-breaking, high porosity, high filtration rate, strong decontamination ability, uniform filter material, and long service life. |
Performance parameters of foam filter beads |
Particle size 0.8-1.2mm, bulk density: 80Kg/m3, porosity: 50%. |
Features |
1. The filter material is a high-molecular polymer, no harmful substances are eluted, and it has good hygiene Energy and water purification performance, not only for sewage treatment, but also for water supply treatment process middle. |
2. The shape is regular, the biofilm is evenly attached, the surface is microscopic and it is easy to hang the film, and it is microorganisms Growth provides a good carrier. |
3. Low specific gravity, suspended in water, making microorganisms show excellent activity, easy backwashing, and significant energy saving. |
4. Insoluble in water, very low water wettability. |
5. Moderate mechanical properties, tight molecular structure, good wear resistance, and not easy to deform during operation. |
6. Stable chemical performance, less filter material loss. |
