Diverse Applications of Bipolar Membranes
Pärnamäe R, et al. Journal of Membrane Science, 2021, 617: 118538.
A bipolar membrane (BPM) is a polymer membrane composed of two layers: a negatively charged cation exchange layer (CEL) and a positively charged anion exchange layer (AEL). Protons and hydroxide ions can be produced through a water dissociation mechanism. This unique property makes bipolar membranes attractive for various applications in many fields, such as the (bio)chemical industry, food processing, environmental protection, and energy conversion and storage.
· Bipolar membrane applications:
· Acid-base production and recovery
· Alkoxide production
· Production and recovery of ammonia
· Capture of CO2 and SO2
· Water and sludge treatment
·BPM-assisted energy applications
