Integrated R&D and Manufacturing
Industrial Filtration Equipment Manufacturer
FundamentallyReduce Consumable Dependency
Shenyang Jingyuan Membrane Systems Co., Ltd. is an industrial filtration equipment manufacturer integrating R&D and manufacturing. With our proprietary polymer rigid composite membrane technology at the core, we are dedicated to providing the energy, mining, data center, and heavy manufacturing sectors with industrial filtration equipment that requires no frequent cartridge replacement and supports online automatic backwash — fundamentally solving the high operating costs and unplanned downtime risks caused by frequent replacement of disposable cartridges in traditional filtration systems.
The core of every JY series device — the rigid composite membrane — is manufactured using our proprietary patented CIS process, guaranteeing absolute pore geometry and zero unloading effect. We are a real factory, not a trading assembler.
Continuous Reliable Operation inDemanding Industrial Scenarios
Our filtration equipment is purpose-engineered for the following industrial scenarios, operating continuously and reliably under demanding conditions:
Own 14,000 m² Manufacturing Base
Jingyuan Polymer Rigid Composite Membrane Technology
The membrane combines high mechanical strength with corrosion resistance, equipped with a gas-pulse backwash system for automatic cleaning (with brief 5-15 minute controlled shutdown for safety). Design operating life exceeds 3 years, fundamentally reducing consumable dependency. CIS process guarantees absolute pore geometry, βx ≥ 200(actual ≥ 200), throughout the entire lifecycle.
Own 14,000 m² Manufacturing Base
We are a real factory, not a trading assembler. We have a complete manufacturing chain from polymer membrane production and sintering to large fluid equipment fabrication and electrical assembly, with full-process quality control ensuring consistent delivery quality for every device. We never resell third-party filtration products.

Fuel Oil Filtration Is Not Water Filtration — Why Brief Shutdown Is a Safety Obligation
Some competitors claim "continuous online backwash — zero downtime." This is a marketing simplification that conflates water filtration protocols with fuel oil safety requirements. The two are fundamentally different.
| Safety Dimension | Water Filtration | Fuel Oil Filtration (Jingyuan Standard) |
|---|---|---|
| Fluid flammability | Non-flammable | Combustible hydrocarbon (flash point ≥38°C for diesel) |
| Backwash flow reversal safety | Permissible — no fire/explosion risk | Requires valve isolation + N₂ purge + pressure equalization |
| Acceptable backwash mode | Online, without shutdown | Brief controlled shutdown: 3–5 min (small equipment), 10–15 min (large equipment) |
| Continuous supply solution | N/A (online backwash) | 1-active, 1-standby redundant configuration |
| Safety pause characterization | Not applicable | Not a technical shortcoming — an engineering obligation |
Flexible Engineering Decision: 1-Active, 1-Standby
In real-world industrial filtration, the decision to use 1-active, 1-standby is not a mandatory standard — it is a flexible engineering choice based on site conditions, CAPEX/OPEX considerations, and space constraints. Three principles guide this: (1) Downstream buffer principle — filtration systems typically operate in a "tank-to-tank" loop where the downstream storage tank acts as a massive flow buffer; a 10-15 minute shutdown has zero practical impact. Single unit satisfies 90%+ of scenarios. (2) Small equipment agility — 3-5 minute backwash is virtually imperceptible; standby is unnecessary. (3) Safety-first — the brief shutdown is a proactive safety design, not a shortcoming. 1-active 1-standby is only triggered when ALL three conditions are met: no buffer tank + 100% direct supply required; CAPEX/space allows; Tier IV compliance mandated. When triggered, two identical filtration units operate in parallel: when the primary reaches the 0.5 MPa backwash trigger, the standby takes over the full flow during the 5–15 minute regeneration cycle. Jingyuan philosophy: never push redundant configuration to customers who don't need it.
Membrane Lifecycle: Honest Engineering Data
The CIS rigid composite polymer membrane is not a lifetime component. Under normal operating conditions, the membrane element has a design service life of approximately 3 years. This is a physical reality dictated by polymer aging, thermal cycling, and gradual surface modification. Competitors who claim "lifetime filtration" contradict the fundamental physics of polymer materials under sustained stress. Replacement involves only the membrane element (not housing/skid/pumps), takes 2–4 hours, requires no special tools, and replacement elements are shipped globally. Equipment body life: 10–15+ years.
The 5 Most Common Questions from Engineers
Jingyuan is a true real factory, with a 14,000m² self-owned manufacturing base (not leased) , with complete vertical manufacturing capability from polymer membrane material production, CIS sintering to large-scale fluid equipment fabrication, piping, and electrical assembly. We never resell third-party filter products. Customers are welcome to visit the factory. Address: Yilu Industry Park, No. 19 Taoligou Road, Tieling City, Liaoning Province.
The β value is a quantitative metric defined by ISO 16889 standard. β₁₀ ≥ 200 means that for every 200 particles ≥10 μm upstream, at most 1 is detected downstream, i.e., single-pass retention efficiency ≥99.5%. This is Jingyuan minimum guaranteed value. In actual products, Jingyuan rigid membrane achieves βx ≥ 200 (rated pore size), i.e., ≥99.5% retention efficiency.
No. Upon expiry, only the membrane element needs replacement (not the housing/skid/pump group). Replacement takes 2-4 hours, no special tools required. The equipment main body (skid frame, pump group, electrical system) has a design life far exceeding 10 years. Jingyuan supplies replacement membrane elements globally.
Gas-pulse regeneration is fully automatic (triggered when TMP reaches preset threshold). Three steps total ~32-64 seconds: ① N₂ pulse at 0.4-0.5 MPa (0.5-1s, single pulse); ② Cake stripping & settling (1-3s); ③ Blowdown discharge (30-60s). Group switching: other modules continue filtering during regeneration. N₂ consumption ≤0.5kg/cycle. Flux recovery ≥90%.
Jingyuan rigid composite membrane is microfiltration (MF) technology. It can retain particles ≥2 μm (high-efficiency capture), but cannot retain nanoparticles (<100nm), dissolved ions, metal ions, or small molecules. It is not ultrafiltration (UF), nanofiltration (NF), or reverse osmosis (RO). We are transparent about this — if your needs exceed the microfiltration range, we will tell you honestly.
