The research in this laboratory is closely connected with the main component of membrane separation processes – the membrane. Here we investigate the properties of materials for the development of membranes, i.e. some mechanical and electrochemical parameters (swelling capacity, resistivity, permselectivity), and suitability for further use.

R&D Programme

WE OFFER
• Comprehensive characterization of ion-exchange membranes and ion-exchange resins – the customer can send us their samples.
- measurement of the ion-exchanger swelling,
- measurement of the ion-exchange capacity of ion-exchanger (IEC), granulate, membrane foil (MF), ion-exchange membranes (IM),
- measurement of the ion-exchanger humidity after drying operation – inter-operational check (MOK),
- measurement of the ion-exchanger humidity after the grinding operation – MOK, continuous inspection of the ion-exchanger processing,
- measurement of the size distribution of the ground ion-exchanger particles,
- total capacities of ion-exchangers,
- sheet and specific resistance of IM,
- permselectivity, anti-ion transference number of IM,
- microscopic examination,
- hydraulic permeability,
- physical properties of IM (change of weight, width, and thickness in the dry and wet conditions).
- Processing of measured data in tables, graphs, final reports, and statistical evaluation, including long-term statistics (upon customer’s request).
• Consultations.
