The CuT40-15-8040 Nanofiltration Membrane for Copper Recovery is an 8-inch spiral-wound nanofiltration membrane element designed for copper- and nickel-bearing water treatment. It supports metal concentration and partial desalination in electroplating rinse-water recycling and other industrial water reuse systems.
With a nominal molecular weight cutoff of 100 Da, an effective membrane area of 37 m², and a maximum operating pressure of 15 bar, the element provides an option for projects that need to retain valuable metals while allowing part of the dissolved salt load to pass into the permeate.
Membrane selection and system performance depend on feed chemistry, operating conditions and the required concentrate and permeate quality.
Key Features

for compatible acidic and near-neutral feed streams.
Partial salt removal
specified sodium sulfate and sodium chloride rejection values support assessment of salt separation requirements.
Copper Recovery from Industrial Wastewater
Copper- and nickel-bearing rinse waters contain dissolved metals that may have recovery value. A membrane concentration system separates the feed into two streams:
Concentrate: a smaller stream enriched in retained metals for further treatment or recovery.
Permeate: a stream with reduced concentrations of retained components, assessed for reuse or additional polishing.
The CuT40-15-8040 Nanofiltration Membrane for Copper Recovery is designed for this concentration step. Depending on the application, the concentrate may be evaluated for return to a compatible process or for downstream metal recovery.
This membrane concentrates metal-bearing solutions; production of a recovered metal product requires an appropriate downstream process.
The CuT40-15-8040 membrane combines a nanocomposite membrane structure with a nominal 100 Da molecular weight cutoff.The specified salt rejection values are 98.5% for sodium sulfate and 69% for sodium chloride.For copper and nickel applications, feed testing should establish metal retention, permeate quality and achievable concentration under the proposed operating conditions.

Applications
Electroplating Rinse-Water Recycling
Evaluate the CuT40-15-8040 for concentrating copper or nickel from segregated plating rinse waters. Permeate reuse depends on the rinsing process requirements and the measured residual metal and salt concentrations.
PCB Manufacturing Wastewater Treatment
The membrane can be considered for compatible copper-bearing rinse streams from printed circuit board manufacturing. Acidic etching solutions, oxidants and complexing chemicals require a separate compatibility assessment.
Copper and Nickel Process-Water Concentration
For metal-processing facilities, the element may form part of a treatment system that concentrates dissolved metals ahead of a selected recovery process.
Battery-Recycling and Hydrometallurgical Streams
Selected metal-bearing streams may be evaluated where pH, dissolved salt content and chemical compatibility fall within the membrane's approved operating conditions. Testing is required for concentrated leachates and chemically complex feeds.
System Design and Pretreatment
Reliable operation starts with a representative feed analysis and pretreatment suited to the application.
Before membrane selection, assess:
- Dissolved copper, nickel and other metals.
- pH, temperature, conductivity and total dissolved solids.
- Suspended solids, turbidity and SDI.
- Hardness, sulfate and potential scale-forming compounds.
- Oils, organic contaminants, oxidants and complexing agents.
- Required permeate quality and concentrate destination.
Cartridge filtration may form part of the pretreatment system, but it does not replace treatment for dissolved foulants, oils or incompatible chemicals. Antiscalant selection and dosing should be based on feed chemistry and projected concentrate conditions.
Installation, Monitoring and Cleaning
Check the element dimensions, pressure vessel, interconnectors, seals and flow direction before installation in a new or existing system.
During operation, monitor feed pressure, concentrate pressure, permeate flow, temperature and water quality. Track normalized performance where applicable to distinguish fouling from changes in operating conditions.
Select cleaning chemicals and procedures according to the membrane supplier's approved guidance and the identified foulant. Confirm cleaning pH, temperature, concentration and contact time before use.
Water Reuse and Downstream Treatment
The required treatment configuration depends on the end use of the water and the intended metal recovery route.
A project may combine pretreatment, nanofiltration, concentrate handling and permeate polishing. Where a process requires lower conductivity or lower residual metal concentrations than the NF permeate provides, additional treatment may be necessary.
Define water reuse acceptance criteria before system design. Evaluate membrane performance against those criteria using representative feed samples.
Frequently Asked Questions
Q: What is the CuT40-15-8040 membrane used for?
A: It is designed for membrane concentration of copper-bearing water, with applications in electroplating rinse-water recycling and selected industrial wastewater treatment systems.
Q: What copper recovery rate can I expect?
A: System recovery depends on metal retention, feed composition, water recovery, staging and downstream concentrate handling. Request a performance assessment using your feed analysis and, where necessary, pilot-test results.
Q: Can the permeate be reused directly?
A: Direct reuse is possible only when the measured permeate quality meets the receiving process requirements. Some applications require additional polishing.
Q: What is the maximum operating pressure?
A: The specified maximum operating pressure is 15 bar. The system must also remain within the approved temperature, flow and pressure-drop limits.
