Oil Filter Fabric N-Fiber F75 Bignanotech 2026: Vietnamese Nano Solution Removes 99% of Oil and Grease, Meets QCVN 40:2025 & Decision 04/2026
Are you facing the problem of factory wastewater always having a thick layer of oil scum, difficult-to-separate emulsified oil, leading to oil and grease parameters exceeding QCVN standards, with the risk of heavy administrative fines or suspension of operations? Especially in the context of Decision 04/2026/QĐ-TTg (effective from February 10, 2026) tightening regulations on oil spill response and QCVN 40:2025/BTNMT (effective from September 1, 2025) imposing stricter limits on mineral oil and grease in wastewater.
Oil filter fabric N-Fiber F75 from Bignanotech is the Made-in-Vietnam nano solution trusted by hundreds of enterprises in 2026. The product not only filters oil cleanly but also helps save costs up to 50%, is easy to install, and fully complies with the latest environmental regulations.
Oil Filter Fabric N-Fiber F75
What is Oil Filter Fabric N-Fiber F75? Advanced Nano Technology from Japan
Oil filter fabric N-Fiber F75 is a specialized oil filter fabric roll produced from 100% recycled polypropylene combined with Japanese nano technology (ultra-fine fibers only 1/800 the diameter of a human hair). The product has hydrophobic properties (completely water-repellent) and oleophilic properties (strongly attracts oil), retaining only surface oil and emulsified oil while allowing clean water to flow through freely.
Outstanding features:
- Characteristic gray color, roll form, easy to cut and sew according to needs.
- Unit weight: 0.5 kg/m².
- Standard size: 75m length × 1.5m width × 5mm thickness (custom sizes available upon request).
Completely different from conventional oil absorbent cotton or expensive mechanical filtration systems, Oil filter fabric N-Fiber F75 thoroughly treats both floating oil and emulsified oil – a persistent challenge for many mechanical plants, CNC workshops, food processing facilities, and auto garages.
Detailed Technical Specifications of Oil Filter Fabric N-Fiber F75 (According to the Manufacturer)
Here is the latest technical parameter table updated by Bignanotech in 2026:
| Technical Parameter | Detailed Value | Practical Notes |
|---|---|---|
| Oil retention capacity | 20 times fabric weight (~10 kg oil/m²) | Depending on oil type (gasoline, diesel, machine oil, grease…) |
| Filtration efficiency | 99% surface oil & emulsified oil | Outlet water is clear, odorless, no scum |
| Maximum water flow rate | 250 m³/hour | No clogging, suitable for continuous 24/7 discharge |
| Reusability | 3–5 times | Squeeze/extract to recover oil, efficiency decreases gradually ~30%/time |
| Roll size | 75m x 1.5m x 5mm (customizable) | Easy to cut, sew into bags/funnels/frames |
| Technology & Material | Japanese Polypropylene Nano | Manufactured in Vietnam, environmentally friendly |
| Others | No oil leakage, no wear, non-flammable/explosive | Recyclable, no secondary pollutants generated |
Super Effective Operating Principle
- Wastewater containing oil flows through the nano fabric layer.
- Nano fibers firmly trap oil within the structural matrix, without releasing it.
- Clean water flows through at high speed (250 m³/hour).
- When the fabric turns dark gray (oil saturated) → replace or squeeze to recover oil for reuse.
Result: Treated wastewater meets QCVN standards from the very first use, reducing the risk of legal violations.

Practical 4-Step Usage Guide
No electricity required, no chemicals, anyone can do it:
- Cut & Design: Cut the fabric to the required size, sew into filter bags, funnels, frames or barriers.
- Installation: Place at drain outlets, discharge pipes, 3-compartment septic tanks, sedimentation tanks, sewers, manholes…
- Operation: Let wastewater flow through → oil is completely retained.
- Maintenance: Check periodically. When oil-saturated → squeeze/extract to recover 85-90% of oil, reuse 3-5 times. When expired → dispose as hazardous waste.
Optimization tip: Combine with N-Fiber oil absorbent sheets and floating booms to create a comprehensive oil treatment system from A to Z.
Real Benefits Enterprises Care About Most in 2026
- Superior cost savings: Vietnamese pricing, 50% cheaper than imported filtration systems, no electricity or chemical costs, reusable multiple times.
- Strict legal compliance: Helps wastewater meet QCVN 40:2025/BTNMT (stricter limits on mineral oil and grease) and complete oil spill response plans according to Decision 04/2026/QĐ-TTg. Reduces the risk of fines of hundreds of millions of VND or operational suspension.
- Environmental & Brand Protection: Reduces pollution of rivers, streams, and seas, demonstrates green responsibility – a competitive advantage in bidding and export.
- Wide application: Mechanical plants, CNC, auto garages, industrial kitchens, plastic/chemical/food factories, seaports, petroleum depots, industrial parks…
Quick Comparison with Other Solutions
- N-Fiber F75: 99% efficiency on emulsified oil, high flow rate, low cost, easy to use.
- Mechanical filtration systems: Average efficiency on emulsified oil, high cost, complex installation.
- Coagulant chemicals: Create secondary sludge, continuously high operating costs.
