Polyester fiber balls are widely used in wastewater treatment and water purification due to their lightweight and high adsorption properties. However, product quality varies between manufacturers, affecting filtration efficiency, durability, and cleaning performance.
To help buyers make informed decisions, we conducted a comparative analysis of polyester fiber balls from five different suppliers, assessing key performance indicators such as filtration effectiveness, cleaning ease, and recovery ability.
📌 Key Parameters of Tested Samples:
Diameter: 50mm
Material: polyester fiber
Density: 1.38g/cm³
Filling Density: 70~90kg/m³
Sewage Interception Capacity: 5~26kg/m³
Specific Surface Area: 3000㎡/m³
Packing Method: vacuum bag
Testing Process: How We Evaluated Polyester Fiber Balls
We performed a six-step testing process to evaluate the fiber balls’ filtration, cleaning, and recovery abilities.
Step 1: Soil-Contaminated Water Filtration Test
To test initial filtration performance, we passed soil-contaminated water through the fiber balls under identical conditions, measuring how well they removed impurities.
Step 2: Manual Cleaning Test
After filtration, we manually washed the fiber balls to determine how easily dirt and debris could be removed and if they could return to their original fluffy texture.
Step 3: Machine Wash Cleaning Test
To simulate real-world conditions, we tested the fiber balls in a machine-wash environment, checking for deformation, breakage, or significant texture loss.
Step 4: Post-Cleaning Recovery Test
Once cleaned, we examined how well each fiber ball regained its original shape and assessed any structural or density changes.
Step 5: Green Pond Water Filtration Test
To further validate their effectiveness in real-world conditions, we conducted another filtration test using green pond water with organic contaminants and algae.
Step 6: Vacuum Packing for Shipping
Finally, the cleaned polyester fiber balls were vacuum-packed for storage and shipping, ensuring they remained compressed and protected before delivery.
Conclusion: Key Takeaways from the Polyester Fiber Ball Testing
Our extensive six-step evaluation revealed significant differences in filtration efficiency, cleaning performance, and post-cleaning recovery among suppliers. While all samples shared a 50mm diameter, their density, fiber resilience, and washing durability varied.
