Heat and Mass Transfer Modeling and Experimental Validation of a Novel Freeze Desalination Process
Freeze concentration is a thermal separation process that is used to purify aqueous solutions. One application of recent interest is seawater desalination. For freeze concentration to be an effective desalination method, a high ice growth rate and product purity must be achieved with energy usage …

Heat and mass transfer effects of ice growth mechanisms in water and aqueous solutions
… in industries such as desalination by freezing, freeze drying, freeze concentration and freeze crystallization for food processing, requires insight into the ice growth mechanisms. More so, a novel technology called Eutectic Freeze Crystallization, where water is recovered in the form of ice, …

Application of through-vial impedance spectroscopy as a novel process analytical technology for freeze drying
… the attributes of the product during the entire freeze-drying process (from pre-freezing and annealing to primary and then secondary drying). This measurement approach involves the application of foil electrodes, mounted externally to a conventional glass freeze-drying vial, and coupled to a …

Development of novel fertilizer manufacturing processes using human urine
… which would scale the RO membrane during concentration. Paper 1 and Paper 2 investigated two pre-treatment methods and showed that chemical addition (NaHCO3) and air bubbling can remove 85-98% of the excess calcium ions from the solution, thus significantly reducing potential RO membrane …

Ice Concentration Linked with Extractive Stirrer (ICECLES)
… difficult to analyse at the trace and ultratrace concentrations necessary to ensure safe drinking water. Therefore, a novel sample preparation method was developed as a combination of SBSE and FC to allow trace analysis of drinking water samples. The technique, ICE Concentration Linked with …
