JY-DX40 Skid-Mounted Membrane Separation Fine Filtration System — 40m³/h Rigid Membrane Diesel Purification Skid
Diesel and aviation kerosene supply chains require high-flow purification. Conventional cartridge systems often face frequent replacement, high maintenance cost and long deployment cycles.
JY-DX40 is a standardized high-flow purification solution from Jingyuan. It is equipped with 8 Jingyuan polymer rigid composite membrane groups and an asymmetric gradient pore structure for 40m³/h physical filtration and oil-water separation.
The system integrates a 7.5kW centrifugal pump booster unit and a standardized skid structure with a footprint of about 3.78m². A 30-second pneumatic backwash can restore flux to over 95%, while the membrane module is designed for 2-3 years of service life, supporting reliable source purification for oil storage, aviation fuel support, power plants and port or marine fuel systems.

Typical applications
Refined oil depots and storage bases
Tank-farm circulation purification to address sediment and oxidized gum generated during long-term storage.
Scenario-based diesel fine filtration solution
Covers industrial oil depots in mining, railway and port sectors as well as retail fuel stations, delivering high-precision filtration to protect engines and improve fuel quality.
Power plants and large diesel generator fuel supply
Protects fuel quality, reduces injection-system wear and improves power generation stability.
Port and marine fuel supply systems
Provides clean fuel pretreatment for shore facilities and vessel fuel tanks.
Technical advantages
8 asymmetric-gradient rigid membrane groups
5mm thick-wall polymer composite membranes provide strong impact resistance, full-pH tolerance and aromatic hydrocarbon tolerance, balancing high flux and high capture efficiency (≥98%@≥5µm).
2-3 year long-life low-consumable operation
The system replaces conventional consumable cartridges and significantly reduces long-term maintenance and logistics cost for continuous supply-chain operation.
30-second pneumatic backwash and standardized skid
Pure physical filtration with no chemical additives. Pressure monitoring prompts backwash, restoring flux to over 95%, and the skid structure supports rapid deployment and connection.

FAQ
How long is the membrane module service life?
The designed service life is 2-3 years. Fast backwash significantly lowers operation and maintenance cost.
How long does backwash take?
Only 30 seconds of gas-pulse backwash is required to restore initial flux to over 95%.
Does it require complex civil installation?
No. The standardized skid design enables quick site connection and commissioning.
Is it suitable for low-flash-point media?
It is only suitable for diesel and aviation kerosene with flash point ≥38°C. Gasoline and similar media are strictly prohibited.
How effective is free-water removal?
It can separate free water, with removal efficiency up to ≥95%.
Is customization supported?
Yes. Stainless steel material, automated control and other flow/interface configurations are available.
Will filtration efficiency decline over time?
A 30-second gas-pulse backwash effectively removes retained solids and restores membrane flux to more than 95% of the initial state.
What contaminants does it target?
It physically intercepts particulate impurities such as sediment and also removes free water, improving fuel cleanliness.
