A Reverse Electrodialysis stack has been shipped by project partners SUEZ to Palermo and has been safely received by project partners ResourSEAs. The stack has already been assembled and some preliminary tests have been carried out to verify the hydraulic seal. The first phase of the laboratory experimental campaign has started and will continue over the next few months.
The SEArcularMINE sampling campaign continues this season across the Mediterranean Basin. Project Partners iBET, based in Lisbon, returned to the nearby Samouco Saltworks this week to collect samples for analysis.
In common with many ancient saltworks across Europe, Samouco is also a protected Natural Reserve. The salt harvesting had been completed the previous week leaving the 'bittern' – the pink residual waste liquid targeted by the SEArcularMINE project - clear to see.
These samples were collected send to partners UPC in Barcelona for analysis. SEArcularMINE in developing innovative processes to recover valuable minerals from these ‘waste’ products.
SEArcularMINE partners UNIPA have made good progress in their research on crystallization (part of WP3). Focusing on crystallization of Magnesium Hydroxide (Mg(OH)2), the team has successfully applied a novel colorimetric technique to infer the crystallization kinetics of the compound. These data provide fundamental insights that can be applied to the design of novel Magnesium crystallisers.
Within Task 6.2, the UNIPA and UPC team have been exploring the recovery of additional minerals from exhausted bittern solutions from saltworks using Electrodialysis with Bipolar Membranes (EDBM) technology.
