In this paper, we focus on a batch protein crystallization process used to produce tetragonal hen egg white lysozyme crystals and present a comparative study of the performance of a model predictive control (MPC) strategy formulated to account for crystal shape and size distribution with conventional operating strategies used in industry, namely, constant temperature control (CTC) and constant ...

Coal-mine effluent treatment has the potential to both reduce environmental impact of and provide economic opportunities by recovering valuable minerals clean water. In this study, we modeled a novel process, which includes nanofiltration (NF), two-step crystallization, reverse osmosis (RO), electrodialysis (ED), multi-effect distillation (MED), NaCl crystallizer, performed techno-economic anal...

BACKGROUND Possession of gas vesicles is generally considered to be advantageous to halophilic archaea: the vesicles are assumed to enable the cells to float, and thus reach high oxygen concentrations at the surface of the brine. RESULTS We studied the possible ecological advantage of gas vesicles in a dense community of flat square extremely halophilic archaea in the saltern crystallizer pon...

The problem of brines disposal has raised great interest towards new strategies for their valorisation through the recovery minerals or energy. As an example, spent brine from ion exchange resins regeneration is often discharged into rivers lakes, thus impacting on process sustainability. However, such can be effectively reconcentrated, after removal bivalent cations, and reused regeneration. T...
