Fiber Ball Filter

The fiber ball filter is a new type of precision water treatment equipment in the filter press industry. Previously, dual-media filters, walnut shell filters, and sand filters were commonly used in the treatment of oily wastewater reinjection. Traditional fine filtration technologies, particularly in low-permeability oil reservoirs, are no longer sufficient to meet the water injection requirements. However, the fiber ball filter meets the standards for oily wastewater reinjection. It is made from a specialized fiber filament synthesized using a novel chemical formula. Its key feature lies in a fundamental improvement, transforming the fiber filter media from oleophilic to hydrophilic. The high-efficiency fiber ball filter utilizes approximately 1.2-meter-long polyester fiber balls in the filter layer, with raw water flowing in and out from top to bottom.

Polyester fiber ball filter media features low density, excellent flexibility, compressibility, and a high porosity. During pressure filtration, the fiber balls intertwine to form a dense and evenly distributed filter layer. The fiber balls, with their unique properties, such as their large surface area and porosity, absorb impurities while retaining suspended particles in the water, fully utilizing the filter media's deep-seated pollution interception capabilities. Fiber balls are also less susceptible to oil contamination, making backwashing easier, though this will also reduce water production to a certain extent. They also offer advantages such as wear resistance and strong chemical stability. When the filter media is severely contaminated with organic matter, it can be recycled through chemical cleaning, making it highly practical.

Product Advantages

1. High Filtration Precision: The removal rate for suspended solids in water is nearly 100%, and it also significantly removes impurities such as bacteria, viruses, large organic molecules, colloids, and iron.

2. Fast Filtration Rate: The typical filtration rate is 30-45 m/h, with a maximum of 80 m/h, approximately two to three times the filtration rate of other granular filter media (such as anthracite, quartz sand, and magnetite). To achieve the same precision requirements, modified fiber ball filters only require one stage of filtration, while dual-media filters and sand filters require two or more stages. To achieve the same treatment capacity, modified fiber ball filters require a much smaller tank diameter and can improve wastewater treatment performance by one stage. 3. High Sewage Interception Capacity: Typically, the filter intercepts 5-15 kg/m², more than double the capacity of traditional quartz sand filters.

3. High Overall Cost-Effectiveness: Given the same treatment capacity and influent specifications, modified fiber ball filter media can reduce equipment investment by over 50% (performance-price ratio) compared to other filter media, while also improving wastewater treatment performance by a level.

4. Small Footprint: For the same water output, the footprint is less than one-third that of a quartz sand filter.

5. Low Cost Per Ton of Water: Backwash water consumption is only approximately 2% of the water output, particularly since influent water can be used for backwashing. Consequently, the cost per ton of water is approximately one-third that of traditional filters.

6. Low Water Consumption: Water consumption is only 1-3% of the cycle water consumption, and raw water can be used for backwashing.

7. No Filter Element Replacement Required: If the filter element becomes contaminated, it can be easily cleaned and filtration performance restored. 9. Easy Backwashing: During backwashing, the fiber filter media is fully loosened, and the combined action of bubbles and water ensures thorough backwash regeneration.

8. High Mechanical Strength, Long Service Life, Simple Operation, Easy Maintenance, and Reliable Operation: The high-molecular-weight polypropylene fiber filter media has a service life of over ten years. Its strength exceeds that of quartz sand, and it will not break down or leak under standard filtration and backwashing conditions.

Applications

1. Widely used in circulating water sidestream filtration, deep domestic water treatment, boiler feed water treatment, reverse osmosis pre-filtration, and wastewater reuse filtration.

2. Suitable for coarse, medium, and fine filtration during the reinjection of oily wastewater from oilfields, as well as for wastewater treatment at oilfield and refinery outlets.

3. Suitable for recycling and filtration of industrial circulating water, domestic water, and wastewater in industries such as steel, thermal power, shipbuilding, papermaking, pharmaceuticals, chemicals, textiles, food, beverages, tap water, and swimming pools. 4. Applicable to various water treatment projects such as pure water, seawater, brackish water desalination, centralized water supply projects and urban sewage treatment projects.
