Industrial RO Membranes for Process Water and Reuse
Reverse-osmosis elements sourced for industrial desalination, process water and reuse duties after suitable pretreatment.
Product overview
A pressure-driven barrier for dissolved contaminant reduction
Reverse osmosis uses pressure to move water through a semi-permeable membrane while rejecting a portion of dissolved salts and other contaminants.
RO element selection must be based on feed analysis, temperature, recovery, pressure, scaling potential, organic fouling risk and the complete array design.
Application fit
Typical roles and use cases
These are potential roles, not guaranteed performance claims. The complete process and verified product limits must be reviewed.
Wastewater reuse
Advanced treatment after upstream solids, organics and biological risks are managed.
Replacement elements
Review of current model, vessel size, array and operating data.
Selection
What needs to be confirmed
- Full ionic water analysis
- SDI, turbidity and solids control
- TOC/COD and biological fouling risk
- Temperature, pH and oxidant exposure
- Design permeate flow and recovery
- Concentrate disposal limits
- Antiscalant and cleaning strategy
- Pressure vessel and current element dimensions
Important
Use approved supplier data
Published nominal performance is measured under defined test conditions and is not the same as site performance. System projection and water analysis are required.
Technical parameters
Specifications to confirm before supply
| Parameter | Published value | Selection note |
|---|---|---|
| Reference models | YF-BW-4040 / YF-BW-8040 | Brackish-water RO reference models; confirm the selected grade and revision. |
| Nominal membrane area | 7.2 / 37 m² | YF-BW-4040 / YF-BW-8040 reference values. |
| Nominal permeate flow | 9.5 / 41 m³/day | Supplier laboratory reference, not a site production guarantee. |
| Nominal salt rejection | 99.7% | Reference test result under the stated catalogue conditions. |
| Reference test conditions | 2000 ± 50 mg/L NaCl; 1.55 MPa; 25 ± 1°C; pH 7–8 | Element recovery reference: 15% for 4040 and 8040. |
| Maximum feed pressure | 4.14 MPa | Coordinate element, housing, pump and piping design limits. |
| Reference pH and temperature | Operation pH 3–10; cleaning pH 2–12; up to 45°C | Verify current datasheet and chemical procedure before use. |
| Pretreatment reference limits | Turbidity ≤1 NTU; SDI15 ≤5; free chlorine ≤0.1 mg/L | Feed-water projection and pretreatment review remain required. |
System context
The element is one part of the RO system
Pressure vessels, pumps, instrumentation, dosing, pretreatment and controls determine whether the selected RO element can operate reliably.
- Provide a complete ionic analysis
- State average and peak permeate demand
- Identify feed temperature and recovery target
- Share the current array for replacement work
FAQ
Common selection questions
Can RO treat industrial wastewater directly?
Usually not without substantial pretreatment. Solids, organics, hardness, metals, silica, oils and biological activity must be controlled.
Can a different RO brand replace the current element?
Potentially, if dimensions and performance characteristics are compatible and the system is re-evaluated.
Does higher recovery always improve the project?
Higher recovery reduces concentrate volume but increases concentration, scaling and pressure risks. The optimum is application-specific.
