Permselectivity pilot

Permselectivity pilot

The Convergence Inspector Permselectivity pilot system is ideal for quality control and R&D on electrodialysis membranes. The system comes with a cell equipped with conductivity sensors. Based on the potential measurement and calculation of the expected potential the permselectivity can be calculated.

Permselectivity pilot

The Convergence Inspector Permselectivity pilot system is ideal for quality control and R&D on electrodialysis membranes. The system comes with a cell equipped with conductivity sensors. Based on the potential measurement and calculation of the expected potential the permselectivity can be calculated.

The membrane is in contact with two circulating electrolyte solutions. Ions with the same charge as the membrane (co-ions) are retained while ions of opposite charge (counter-ions) can pass through the membrane. The permselectivity of a membrane describes the charge selectivity of an ion-exchange membrane.

The user-friendly software interface records flows, temperatures and conductivity. Thus the permselectivity and trans-membrane pressure can directly calculated in the software. The software interface also allows the creation of individual test scripts. Whether you want to perform permeability tests with several different flux or temperature steps, the Permselectivity Inspector has you covered.

The system is highly customizeable and can for example be designed to include additional sensors, in-line heating and cooling. For quick quality testing a membrane module with a closing system can be included allowing the user to very quickly replace the tested membrane and increase the throughput.

Optionals:

  • Cell closing system
  • Customized flat sheet membrane modules
  • Customized flow-, temperature- and pressure range (higher or lower)
  • Heating or cooling system (includes heat exchangers and heating/cooling bath)
  • Pressure control of electrolyte solutions
  • Feed vessels (can also be heated or insulated)
