Flowable Channels

Performance of flow capacitive deionization modules is not only influenced by membranes. The geometry of flow electrode channels has a strong influence on salt adsorption capacity (SAC). Thus, advanced computing project Flowable Channels (CPCA/A0/401985/2021 and CPCA/A1/469450/2021) focus on Optimization of flow electrode channel geometry to boost recovery of lithium from brines by flow capacitive deionization (FCDI).

High performance computing (HPC) resources of the National (Portuguese) Network for Advanced Computing are used to perform computational fluid dynamics (CFD) simulations of the flow of carbon slurries (flow electrodes) in FCDI modules.

The main objective is to improve the design of these flow electrode channels to ensure uniform distribution and mixing of carbon slurries.
