N-FIBER F75 Oil Filter Fabric by Bignanotech 2026: Vietnam’s Nano Solution – Filters Up to 99% of Surface Oil & Emulsified Oil, Flow Rate of 250m³/hour – Compliance with QCVN 40:2025/BTNMT
Are you “headaching” because your factory’s wastewater always has a thick layer of oil scum, emulsified oil that is difficult to separate, leading to violations of discharge standards and administrative fines? Or is your old wastewater treatment system costly in electricity and chemicals, prone to breakdowns, and unable to thoroughly treat dissolved oil?
N-FIBER F75 Oil Filter Fabric from Bignanotech – a 100% Vietnamese nano product – is the optimal solution in 2026. With Japanese Nano technology, the fabric filters up to 99% of both surface oil and emulsified oil, producing crystal-clear water that meets standards, with a flow rate of up to 250 m³/hour, reusable 3–5 times, at a reasonable price and installable in just a few minutes.
Based entirely on official information from the Bignanotech website (bignanotech.com), this article provides the most specific, detailed, and complete analysis of the product: from composition, technical specifications, operating principles, practical usage instructions, diverse applications, economic and environmental benefits, to strict compliance with QCVN 40:2025/BTNMT (effective from 01/09/2025). This is not just an oil filter fabric but a “shield” protecting your business from legal risks under the 2020 Law on Environmental Protection.
What Is N-FIBER F75 Oil Filter Fabric by Bignanotech? Core Features
N-FIBER F75 Oil Filter Fabric (or N-FIBER oil filter roll) is a specialized material for separating and retaining oil from industrial wastewater. The product is designed in gray roll form, easy to cut, sew, and shape according to any usage needs.
- Main composition: 100% recycled polypropylene combined with Japanese Nano technology (super-fine nano fibers 1/800 the diameter of a hair strand).
- Color: Characteristic gray.
- Unit weight: 0.5 kg/m².
- Packaging: 01 roll/bale (size according to customer requirements, commonly L75m x W1.5m x T5mm).
- Core properties: Hydrophobic (does not absorb water) – Oleophilic (strongly attracts oil). The fabric only retains oil and oil-based liquids, allowing clean water to flow through freely, with no oil leakage, no wear, and no corrosion of equipment.
Completely different from ordinary oil absorbent cotton or mechanical filtration systems: N-FIBER F75 thoroughly treats both surface floating oil and emulsified oil (oil that has dissolved like emulsion in water) – the most difficult issue in industrial wastewater.

Detailed Technical Specifications of N-FIBER F75 Oil Filter Fabric (According to Bignanotech Manufacturer)
| Technical Parameter | Detailed Value | Practical Notes |
|---|---|---|
| Oil retention capacity | Up to 20 times the fabric’s weight (about 10 kg oil/m² depending on type) | Depends on oil type (gasoline, diesel, machine oil, grease…) |
| Filtration efficiency | 99% surface oil & emulsified oil | Output water is crystal clear, odorless |
| Maximum flow rate | 250 m³/hour | No clogging, suitable for continuous 24/7 discharge |
| Reusability | 3–5 times (efficiency decreases ~30% after each wringing) | Use wringer or centrifuge to recover oil |
| Roll size | According to requirements (e.g., 75m x 1.5m x 5mm) | Easy to cut, sew into bags/funnels/frames |
| Composition & Technology | 100% recycled polypropylene + Japanese Nano | Manufactured in Vietnam |
| Other properties | No oil leakage, no wear, environmentally friendly | Non-flammable/explosive, no secondary waste generated |
These specifications have been verified through real-world applications at hydropower plants, thermal power plants, plastic manufacturing, and mechanical factories.
Highly Efficient Operating Principle of Japanese Nano Technology
N-FIBER F75 fabric operates based on nano hydrophobic & oleophilic properties:
- Wastewater containing oil flows through the fabric.
- Nano polypropylene fibers retain 100% surface oil + emulsified oil within the nano matrix (without releasing the oil back).
- Clean water flows through freely at high speed (250 m³/hour).
- When the fabric turns dark gray (oil saturated) → replace or wring to recover oil.
Result: Output water is crystal clear, free of oil scum and oil odor, meeting the new standard’s mineral oil and grease limits.
Detailed 4-Step Usage Instructions for N-FIBER F75 Oil Filter Fabric
Extremely simple, no electricity or chemicals required, anyone can do it:
- Cut the fabric to the required size (can be sewn into filter bags, funnels, frames, or rolled barriers).
- Install at: drain outlets, discharge pipe ends, three-chamber tanks, wastewater settling tanks, oil-contaminated discharge pipes, sewers, manholes, pond/canal banks…
- Allow wastewater to flow through → oil is completely retained, clean water flows out.
- Check & maintain: When the fabric is saturated (dark color) → replace or use a wringer/centrifuge to recover oil → reuse 3–5 times.
Important notes: After wringing the oil dry, fold the fabric neatly for next use. When the fabric is damaged or no longer reusable, dispose of it in hazardous waste storage (away from heat, fire, or water sources).
N-FIBER Oil-Absorbent Fabric applied at Hai Phong Port, effectively managing oil spills
Optimization tip: Combine with N-FIBER oil absorbent pads for complete treatment:
- Pads absorb large floating oil (up to 10 times their weight).
- Filter fabric treats remaining emulsified oil.
