Hydroxide Ion Selective Permeable Membrane
The hydroxide ion selective permeable membrane is independently developed by Tingrun. This anion membrane not only possesses the characteristics of a typical anion membrane but also has a high selectivity for hydroxide ions. It effectively retains other anions such as Cl-, SO₄²-, NO3-, with a retention rate of over 95%. Therefore, this membrane can be used to separate salt and alkali. If ion precipitation is not a concern, it can achieve 100% separation of alkali and salt.Properties of bipolar ion exchange membranes :

Working Principle:
Due to the unique property of selective permeability of hydroxide ions, the anion membrane can be stacked with the acid-resistant cation membrane to form an electrodialysis module. This module can then be used to separate alkali and salts in alkaline wastewater, while also concentrating the alkali
Applications:
This can be used to separate alkali and salt in acidic wastewater through electrodialysis, while also concentrating the acidPacking Size
