High-Efficiency Fiber Bundle Filter System for Industrial Water & Chemical Processing

Why Choose Longdai?

1. 10+ Years of Expertise: Specialized in wastewater and sludge treatment solutions.

2. German Technology Integration: Superior performance backed by advanced European engineering.

3. Premium Components: Only high-quality parts from trusted suppliers.

4. In-House R&D and Manufacturing: Full control over innovation and production quality.

Product Overview
The high-efficiency fiber bundle filter is a pressurized filtration system featuring an advanced structural design and exceptional performance. It employs a innovative bundled soft-fiber material as the filter element, with filament diameters ranging from several microns to tens of microns. This design offers a large specific surface area and low filtration resistance, overcoming the accuracy limitations of traditional granular filter media.

The ultra-fine fibers significantly increase the specific surface area and surface free energy, enhancing contact opportunities and adsorption capacity between impurities and the filter material. This results in superior filtration efficiency and dirt-interception performance.

Technical Parameters

Key Features

1. High Filtration Accuracy: Up to 100% removal rate of suspended solids; effluent turbidity ≤2 NTU from 20 NTU influent.

2. Rapid Filtration Speed: Operates at 30 m/h (3–5× faster than conventional filters), with peak rates up to 50 m/h.

3. Large Dirt Holding Capacity: 5–10 kg/m³, 2–4× higher than traditional filters.

4. Adjustable Performance: Customizable filtration accuracy, dirt capacity, and resistance.

5. Compact Footprint: Requires only 1/3 to 1/2 the space of conventional systems for equivalent capacity.

6. Low Tonnage Water Cost: More economical operation compared to traditional filters.

7. Efficient Backwashing: Consumes only 1–3% of periodic output water; typically uses raw water for cleaning.

8. Long Service Life: No filter replacement needed; easily regenerated via cleaning. Filter element lifespan ≥10 years.

Applications
Effectively removes suspended solids, bacteria, viruses, macromolecular organics, colloids, iron, manganese, and other contaminants. Widely used in:

• Power, petroleum, chemical, metallurgical, papermaking, and textile industries

• Food, beverage, municipal water, and swimming pool purification

• Industrial/civil water supply, process water, cooling circulation, and wastewater treatment

Structure & Working Principle
The system eliminates the traditional “capsule water filling” design. It comprises a fixed porous plate, movable porous plate, fiber bundle filter material, and air distribution device. The movable plate adjusts vertically to compress the fiber bundles during filtration, forming a gradient-density filtration layer with combined vertical/horizontal deep-bed filtration.

During cleaning, the fiber bundles are loosened, and combined air-water backwashing is applied. Rising bubbles and hydraulic action keep the fibers in constant motion, thoroughly removing retained impurities and regenerating the filter media.

Packing and Delivery

1. Waterproof packing with the international export standard by 20ft, 40ft, 40hp container. Equipment Fittings, Electric Motor and Power Cabinet will be packed in Wooden Case or Iron Box. Other Equipment will be packed by Color-Stripes Plastic Cloth.
2. The whole plant machinery size are large as normal, so we will use Waterproof cloth to pack all of them. The motor, gear box or other easily damaged parts, we will put them into box. We have a professional shipping department, they will try their best to save your container quantity.
