Today several pallets of Polyester Fiter Ball were delivered to Sweden.
Biological filter is a type of water treatment filter material formed by tying polymer fiber filaments into a spherical shape. It has advantages such as large interception capacity, low backwash water consumption, and long service life. It is widely used in deep purification of sewage treatment, industrial circulating water, and oily wastewater treatment.
Fiber ball filter material is a key filtration material developed to meet increasingly strict water quality standards and the demand for water resource recycling. With the increase in sewage reuse rate and the growing demand for high-purity water in industries such as electronics, chemical, and power, traditional sand filtration is no longer able to meet precision requirements. Fiber balls, with their variable pore structure and high specific surface area, have become an upgraded alternative solution.
Core features and performance parameters
Good elasticity, acid and alkali resistance, and a porosity of up to 96%.
The loading height is usually 120 cm, and it naturally compresses by about 30 cm after entering the water.
The filtration speed range is wide (20-85 m/h), and the interception capacity reaches 6-35 kg/m ³.
The backwashing water consumption only accounts for 1% -2% of the periodic filtration water consumption, with a lifespan of over 10 years.
Ordinary Bio Filter Media are mainly made of polyester/polypropylene, while modified fiber balls undergo surface hydrophilic treatment, significantly improving their adsorption rate for oil substances (up to 98%).
Fiber balls are not a single product, but a filter material system that covers multiple technological generations such as ordinary fiber balls, modified fiber balls, fiber bundles, and comet shaped fiber filter materials; When selecting, it is necessary to consider the quality of the raw water (such as whether it contains oil), effluent standards (such as reuse/discharge), and operation and maintenance conditions (whether automatic backwashing is supported).
