Membrane Distillation (MD) is a thermal process that utilizes the vapor pressure difference between hot and cold sides, separated by a hydrophobic membrane. This process can be powered by waste heat, which helps minimize its carbon footprint. While MD has undergone extensive research at laboratory and pilot scales, its larger-scale deployment faces challenges such as high specific thermal energy consumption, membrane scaling or fouling (especially at high solution concentrations), and low flux.
To overcome these challenges, CORNERSTONE is focusing on studying and implementing novel flow rheology. This approach aims to enhance the thermal energy efficiency of MD while reducing fouling and scaling issues. Additionally, in CORNERSTONE, the MD module will be integrated with non-clogging heat exchangers (Module 1). This integration allows for the utilization of waste heat that would otherwise be dissipated into the environment. By combining these strategies, the project aims to address the limitations of MD, making it more efficient and practical for larger-scale applications with reduced environmental impact.
