Fiber Ball Filter

The fiber ball filter is a high-performance precision filtration device specially designed for water treatment and industrial liquid purification, adopting modified polyester fiber ball as the core filter material. 

Unlike traditional rigid granular filter media (such as quartz sand, anthracite), this filter uses elastic spherical fiber bundles with adjustable porosity, realizing deep-layer high-efficiency filtration through mechanical screening, contact flocculation and electrostatic adsorption effects. It can effectively intercept suspended solids, colloids, oil droplets, bacteria and other micro-impurities in water, with stable effluent quality and strong adaptability to various water quality conditions.

This product breaks through the limitations of traditional filters, featuring compact structure, flexible operation and wide application scenarios. It is suitable for both large-scale municipal water supply projects and small-batch industrial wastewater treatment, and can be used as standalone filtration equipment or supporting purification equipment in the whole water treatment process, providing reliable and efficient filtration solutions for global industrial and environmental protection customers.

Technical Features

High-quality Modified Filter Material: The core fiber ball is made of high-strength polyester fiber through special chemical modification, transforming from oleophilic to hydrophilic property, with excellent anti-oil adhesion, wear resistance and corrosion resistance, avoiding hardening and agglomeration during long-term operation, and ensuring stable filtration performance.

Ideal Porosity Gradient: During the filtration process, the filter layer porosity gradually decreases from top to bottom along the water flow direction, which fits the ideal filter material distribution law. This structure realizes layered interception of impurities, avoids rapid blockage of the filter surface, and greatly prolongs the filtration cycle.

High Precision & Large Flow Filtration: The filtration precision can reach 1-5μm, with a removal rate of over 96% for suspended solids (SS), and can effectively remove micro-impurities that traditional filters cannot intercept. The filtration speed is 20-60m/h, which is 3-5 times that of traditional sand filters, meeting the high-flow treatment needs of industrial scenarios.

Efficient Backwashing System: Adopting gas-water combined backwashing or mechanical stirring auxiliary backwashing mode, the backwashing effect is thorough, and the fiber ball can be completely regenerated. The backwashing water consumption is less than 1%-2% of the cycle filtration water volume, greatly reducing water resource waste and operation cost.

Wide Adaptability to Working Conditions: Applicable to water temperature of 5-60℃, working pressure of 0.1-0.6MPa, compatible with acidic, alkaline and neutral water quality, and can operate stably in harsh industrial environments such as high suspended solids and oil-bearing wastewater.

Core Competitive Advantages

Compared with traditional quartz sand filters, fiber ball filters have obvious comprehensive advantages, which can help customers reduce investment costs, improve operation efficiency and reduce later maintenance pressure, and are the preferred choice for upgrading filtration equipment.

Large Sewage Interception Capacity: The sewage interception capacity is 6-20kg/m³, 3-5 times that of traditional sand filters, reducing the frequency of backwashing and equipment downtime, and improving continuous operation efficiency.

Small Footprint & Low Investment: Under the same treatment capacity, the floor area is only 1/3-1/2 of traditional filters, saving workshop space and infrastructure investment, which is more suitable for limited site conditions.

Long Service Life & Low Maintenance: The fiber ball filter material has a service life of 5-10 years, no frequent replacement required, and the equipment structure is simple, with few vulnerable parts, reducing daily maintenance workload and maintenance costs.

Energy Saving & Environmentally Friendly: Low backwashing water consumption and power consumption, no need to add a large amount of flocculants (flocculant dosage is 1/2-1/3 of traditional processes), meeting global environmental protection and energy saving requirements.

Stable Effluent Quality: Even under the condition of fluctuating influent water quality, the effluent suspended solids can be stably controlled below 2mg/L, meeting the strict discharge or reuse standards of various industries.

Key Technical Parameters

Frequently Asked Questions (FAQ)

Q1: What is the actual filtration precision of the fiber ball filter, and can it remove micro-colloids and oil droplets?

A: The conventional filtration precision of our fiber ball filter ranges from 1μm to 5μm, and customized higher precision models are available. Relying on the deep adsorption effect of modified fiber balls, it can effectively intercept micro-colloids, fine suspended solids and dispersed oil droplets in water, with a removal rate of over 95% for 1μm impurities, which is far better than traditional sand filters.

Q2: How often does the fiber ball filter need backwashing, and how long does each backwashing take?

A: The backwashing cycle is determined by influent water quality and sewage interception capacity. Under conventional working conditions, the backwashing cycle is 8-24 hours; for high-suspended solids wastewater, the cycle is appropriately shortened. Each backwashing time is 10-15 minutes, with thorough cleaning effect, and the fiber ball can be completely regenerated to restore filtration performance.

Q3: What is the service life of the fiber ball filter material, and when does it need to be replaced?

A: The high-quality modified fiber ball filter material has a service life of 5-10 years under normal operation and regular backwashing. It is recommended to check the filter material condition annually; replacement is needed only when the fiber ball is severely worn, broken or loses elasticity, which greatly reduces the cost of consumables replacement compared with traditional filter materials.

Q4: Is this filter suitable for acidic/alkaline wastewater, and what is the applicable pH range?

A: The fiber ball filter has strong corrosion resistance, applicable to water quality with pH value of 4-10, and can operate stably in weak acidic and weak alkaline wastewater. For strong acid/alkali industrial wastewater, we can provide customized anti-corrosion upgraded models to meet special working condition needs.

Q5: Is the installation and commissioning of the fiber ball filter complicated, and does it require professional operation?

A: The equipment has a compact integrated structure, with simple pipeline connection and modular design. We will provide detailed installation drawings and operation manuals, and the commissioning process is simple. Conventional operators can master the operation skills quickly after simple training; we also provide remote technical guidance and on-site commissioning services to ensure smooth equipment operation.
