A new technology for the cost-efficient (up to 95% cost reduction) preparation of membranes from recycling PET was developed at the IOM. A simultaneous modification of the membranes results in an enhanced membrane performance (longer lifetime, lower operating costs) compared to conventionally applied materials like PVDF or PES. A distinctive feature of this development is the combination of membrane production and membrane modification in a one-step process.
The aim of this validation project is to verify the applicability of this technology in a roll-to-roll process for possible large-scale production. The membrane performance will be investigated together with industrial partners for an application in wastewater purification. Further partners for other areas of applications like e.g. preparation of drinking water, filtration in food and beverage industry, medical applications, or chemical industry will be identified during the project.
At the end of the project a number of validated processes for the preparation of membrane filters from recycling PET shall be available for different applications. These membranes will significantly decrease the operations costs of membrane-based processes while also having lower acquisition costs.
