Seeking organisations able to help scale up production of membrane distillation systems for deployment globally
Project Size 250,000 € · Deadline : 2020-03-31
We are working with a developer and supplier of equipment for the sustainable supply of safe drinking water in remote areas. Many remote island communities or those in conflict areas do not have access to a consistent supply of fresh drinking water or a reliable energy source to allow water to be created where it is needed. There is therefore a need for technology to transform non-potable water (polluted, waste, grey, brackish or seawater) into safe drinking water. Reverse osmosis (RO) systems are currently used in large desalination infrastructure projects, but are unsuitable when access or power is restricted, or if supply is required in a short time-frame. Membrane distillation (MD) processes are increasingly being investigated as a potential alternative to RO for these scenarios. The process relies on the partial pressure difference (triggered by a temperature difference) between each side of the vapour-selective and hydrophobic membrane pores. These pores are larger than in RO systems, resulting in less pressure, and subsequently less energy required, which facilitates the use of resulting MD systems in remote, off-grid locations with renewable energy sources.
