High-Performance Plastic Poriferous Bio Balls for Waste Gas and Water Treatment Systems
Bio ball is also called Poriferous ball-shaped suspend packing, which was concentrated two technologies' advantage, that is wastewater treatment and Bio-film reactor. Outer structure is two net-shaped sphere. Inner structure is revolving fans.
This packing can be used for a variety of horizontal acid tanks and condensate and desalting water tanks in water treatment. It reduces the heat loss in large extent and the pollution of dioxide carbon and oxygen to water in acid mist and aire.
It is also widely used for stripping,washing and absorbing in the packing tower in petroleum, chemical, chlor-alkaki, gas and environmental industries.
High-Performance Plastic Poriferous Bio Balls for Waste Gas and Water Treatment Systems
Efficient Filtration with Plastic Bio Cage Balls
Plastic bio balls—also known as poriferous balls or cage balls—are essential components in industrial filtration systems. These innovative products, made from high-quality polypropylene (PP), are used in exhaust gas treatment towers, biological filtration systems, and water purification processes.
Available in 60mm, 80mm, and 100mm sizes, they offer flexibility and customization to meet different process requirements.
What Are Poriferous Bio Balls?
Poriferous bio balls are hollow, spherical plastic structures with a porous surface. Their open design increases surface area, allowing efficient gas-liquid contact and biological colonization. The cage-like construction ensures durability, free flow of fluids, and maximum retention of microorganisms during biofiltration.
These balls are commonly used in the filling layer of waste gas treatment towers, often referred to as plastic “sea urchin balls” due to their spiny appearance.
Key Features and Benefits
Excellent Surface Area
Their 3D structure allows bacteria and biofilm to grow efficiently, improving filtration performance.
Corrosion and Chemical Resistance
Made from high-grade PP (polypropylene), they resist acids, alkalis, and high temperatures.
Lightweight and Durable
Easy to handle, install, and clean. Despite being lightweight, they provide strong mechanical strength.
Versatile Size Options
Available in multiple diameters: 60mm, 80mm, and 100mm, ensuring compatibility with all tower designs.
Eco-Friendly and Non-Toxic
100% recyclable material, safe for use in biological and industrial applications.
Applications in Environmental Systems
Plastic bio cage balls are used in a wide range of systems, including:
Waste gas scrubbing towers
Biological wastewater treatment
Aquaculture filtration
Cooling water circulation systems
Deodorization equipment
They enhance the gas-liquid phase reaction, boost oxygen exchange, and support biological decomposition.

Perfect for Biological Packing Layers
These plastic poriferous balls are ideal for forming the packing layer in exhaust gas treatment towers. When stacked in large numbers, they form a dense but breathable matrix. This structure supports the even distribution of airflow and liquid, improving contact efficiency and system output.
