Bio Ball Filter Media – Cost-Effective Biological Filter Media for Wastewater and Aquatic Systems

Short Description:

Our Bio Ball filter media, also known as spherical suspension filler, is a high-performance solution developed for biological wastewater treatment. Designed for use in aquariums, fish tanks, ponds, and industrial or municipal wastewater systems, these floating media offer a large surface area, excellent biofilm adhesion, and long service life, making them ideal for cost-sensitive yet efficient water treatment needs.

Working Principle

Bio Balls function as carriers for biofilm growth, enabling effective biological filtration. The outer shell—molded from durable polypropylene—features a porous fishnet-like spherical structure, while the inner core consists of high-porosity polyurethane foam, offering strong microbial attachment and suspended solids interception. These features promote aerobic bacterial activity, supporting the breakdown of organic pollutants in aerobic and facultative bioreactors.

When introduced into a treatment system, the media float freely, continuously rotate with water flow, and maximize contact between water and microorganisms, leading to enhanced biological activity without clogging or the need for fixing.

Key Features

• High Specific Surface Area: Up to 1500 m²/m³ for efficient biofilm growth.
• Durable & Stable: Chemically resistant to acids and alkalis; withstands continuous temperatures of 80–90°C.
• Non-Clogging & Free-Floating: No need for brackets or support frames.
• High Porosity (≥97%): Promotes rapid microbial colonization and effective filtration.
• Safe & Eco-Friendly: Made from non-toxic materials; no harmful leachates.
• Long Service Life: Easy to maintain and replace, resistant to aging and deformation.
• Minimal Residual Sludge: Reduces maintenance costs over time.
• Esy Installation: Directly added to filtration tanks or systems.
