Case Study
Stage 1 · Customer Problem
An environmental technology enterprise located in Southeast Asia is dedicated to converting industrial waste lubricants back into high-quality reclaimed base oil through vacuum distillation and hydroprocessing. In the final stage of refining, the oil requires high-precision filtration to ensure appearance and physicochemical indicators.
⚫
Ultra-Fine Carbon Black & Polymers
Fine carbon black and oxidized polymers generated during waste oil reclamation are viscous, and traditional filter paper or bag filter cartridges are easily blocked by residual moisture and sticky substances in the oil.
💧
Moisture Affecting Color
Southeast Asia's high temperature and humidity cause refined oil to absorb moisture during storage and transfer. Trace water makes the oil appear cloudy, affecting the finished product grade.
📐
Filter Media Deformation & Accuracy Loss
The re-refining process has large pressure fluctuations. Ordinary soft filter media stretches under elevated differential pressure, causing already-intercepted particles to break through.
💰
High Operating Costs
Previously used imported consumable cartridge replacement cycles were short, with high annual consumable costs straining the operating budget.

| Filter Material Cost | Baseline (imported cartridges) | −70% | Significant savings |
By introducing the JY-DX40, the factory's reclaimed base oil transparency improved markedly. Particle counts stabilized and moisture was kept within a safe threshold, resolving the oil cloudiness issue. The finished oil visually approached international premium-brand quality, meeting API Group II base oil standards. Thanks to the long service life of the composite membrane, filter material consumption costs were reduced by approximately 70%, effectively lowering the daily maintenance burden.
Stage 5 · Lessons Learned · NEW
✅
Rigid Membrane Prevents Breakthrough
Unlike soft filter media that stretch under pressure fluctuations, rigid composite membrane maintains stable pore size, preventing already-intercepted particles from breaking through and ensuring consistent 3 μm precision.
⚠️
Humidity-Driven Moisture Control
In Southeast Asia's high-temperature, high-humidity climate, coalescence water removal is essential to prevent refined oil from absorbing moisture during storage and transfer, which causes cloudiness and downgrades the finished product.
🔄
Long Membrane Life Reduces TCO
The composite membrane's long service life combined with online CIP functionality reduces filter material consumption costs by approximately 70% versus imported consumable cartridges, delivering strong circular-economy ROI.

Customer feedback
In Southeast Asian lubricant reclamation, controlling moisture and ultra-fine particles is the key to success. The JY-DX40's "oleophilic-permeable + coalescence water removal" performance brings our finished oil visually close to international premium brand quality, while the rigid membrane technology reduces daily maintenance burden. This is an important step in our environmental process upgrade.
