This page explains how Reverse Osmosis Membrane is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A semi-permeable membrane used in reverse osmosis systems to remove dissolved solids, ions, and contaminants from water by applying pressure to overcome osmotic pressure.
Technical details and manufacturing context for Reverse Osmosis Membrane
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Membrane Area | 7.9–37.2 m² | Determines water production capacity |
| Salt Rejection Rate | 99.2–99.8 % | Higher is better for pure water |
| Permeate Flow Rate | 0.5–1.2 m³/h | At standard test conditions |
| Operating Pressure | 1.0–1.6 MPa | |
| Maximum Operating Temperature | 45–80 °C | Above this may damage membrane |
| pH Range | 2–11 | Continuous operation; outside reduces life |
| Membrane Material | PA-CTA | Polyamide or cellulose triacetate |
| Membrane Element Diameter | 2.5–8.0 inch | Common sizes: 2.5, 4, 8 inches |
| Membrane Element Length | 40–60 inch | Standard lengths: 40, 60 inches |
| Maximum Feed Water Turbidity | 1.0 NTU | Higher turbidity causes fouling |
| Maximum Feed Water SDI | 5.0 | Silt Density Index; above 5 requires pretreatment |
| Maximum Feed Water Chlorine Concentration | 0.1 mg/L | Chlorine degrades polyamide membranes |
| Weight | 2.5–20.0 kg | Depends on element size |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The salt rejection rate is typically 99.2% to 99.8%, but this depends on the specific membrane element and operating conditions. Always verify with the manufacturer for your application.
The maximum operating temperature is 45 to 80 °C. Exceeding this range may damage the membrane. Confirm the exact limit for your model.
The maximum feed water chlorine concentration is 0.1 mg/L. Higher levels can degrade polyamide membranes. Use dechlorination pretreatment if needed.
Common element diameters are 2.5, 4, and 8 inches, with lengths of 40 to 60 inches. The weight ranges from 2.5 to 20.0 kg depending on size.
