Product Description
The plastic porous suspended biological filler, designed in a hollow spherical structure with a sponge-like interior cage, is an advanced biofilm carrier used in biochemical ponds and wastewater treatment systems. This innovative filler integrates polyurethane sponge with a lightweight plastic shell, offering high porosity and excellent bio-adhesion performance, making it ideal for aerobic and anaerobic biological filtration processes.
Also referred to as the polyurethane hollow sponge cage floating ball, this filler features a dual-layer design: the outer shell is a fishnet-style hollow plastic sphere, while the inner core contains a rotatable sponge segment made of high-density polyethylene or polyurethane. This configuration enhances microbial colonization and provides a large active surface area for effective biological treatment.
Key Features
- High Specific Surface Area – Increases contact between water and microbes, improving treatment efficiency.
- Excellent Biofilm Support – Allows rapid microbial growth and stable attachment.
- Outstanding Hydrophilicity – Promotes water flow and accelerates biofilm formation.
- Chemical & Biological Durability – Resistant to acids, alkalis, and long-term degradation.
- Eco-Friendly Composition – Made from non-toxic materials, prevents secondary pollution.
- UV & Aging Resistant – Durable under sunlight and outdoor conditions.
