Ion-exchange membrane characterization for performance-based selection
The performance of an electromembrane process depends strongly on the properties of the ion-exchange membranes used. Membrane resistance, selectivity, water uptake, swelling, chemical stability and mechanical behaviour can directly affect energy consumption, product quality and process lifetime.
GREENNOVATION helps industrial teams characterize, compare and qualify ion-exchange membranes using relevant technical data.

We support membrane selection, supplier comparison, internal material development and process validation.

This service is useful when:

You need to compare several commercial membranes

You are developing a new membrane material

You need reliable data before selecting membranes for lab or pilot trials

Datasheet information is not enough for your process

You need to understand why one membrane performs better than another

You want to benchmark your membrane against commercial references
GREENNOVATION can help assess key ion-exchange
membrane properties such as:
- Electrical resistance
- Conductivity
- Permselectivity
- Ion-exchange capacity
- Water uptake
- Swelling and dimensional stability
- Mechanical behaviour
- Ageing and degradation
- Comparative performance between membranes
The objective is not only to measure properties, but also to interpret what they mean for your application
We work with:

Cation-exchange membranes

Anion-exchange membranes

Bipolar membranes

Commercial membranes

New membrane materials

Reinforced or composite ion-exchange membranes
Deliverables can include:

Membrane characterization report

Comparative membrane benchmark

Measurement protocol

Interpretation of performance differences

Recommendations for membrane selection

Suggestions for further testing

Choosing the wrong membrane can increase resistance,
reduce current efficiency, lower product purity or create problems during scale-up.
