Porous Floating Spheres (PFS) are a new type of water treatment material, typically made of high polymer materials with a porous structure, providing ample surface area for microbial attachment. This material is commonly used in biofilm reactors, such as MBBR systems, to enhance wastewater treatment efficiency.

The main features and advantages of the porous suspended spheres include:

High Specific Surface Area: The porous suspended spheres possess a high specific surface area, which means they can support a large amount of microbial growth, thereby enhancing the efficiency of biological treatment.

2. Excellent Mechanical Strength: These spheres typically possess good mechanical strength, capable of withstanding mechanical stresses that may be encountered during the biological treatment process.

3. Adjustable porous structure: The pore structure of the porous suspended spheres can be designed and adjusted as needed to optimize water flow and oxygen transfer, while also facilitating the immobilization of microorganisms.

4. Flexible packing density: Due to the lightweight nature of the porous悬浮 spheres, they can be suspended at a lower packing density within the reactor, thus reducing the reactor's volume and saving space.

5. Easy to regenerate and replace: After a period of use, the porous suspended spheres can be cleaned and regenerated to restore their performance. When their performance can no longer be restored, they can be safely replaced without causing environmental pollution.

6. Suitable for various water qualities: The porous suspended spheres are applicable for treating a variety of wastewater types, including urban, industrial, and agricultural wastewater treatments.

The application of porous suspended spheres in water treatment can enhance biological treatment efficiency, reduce energy consumption and operational costs, while also contributing to the sustainable use of water resources and environmental protection.
