How wastewater in China can be processed in a more resource-efficient manner is the subject of a new German-Chinese research project. Among other things, topics include how phosphorus can be extracted from wastewater as well as new processes that purify water with higher energy efficiency. The "PIRAT-Systems" project is coordinated by Professor Heidrun Steinmetz. She is head of the Department of Resource Efficient Wastewater Technology at the Technical University of Kaiserslautern (TUK). Steinmetz's team will be working with project partners in Germany to adapt tried-and-tested technologies to the Chinese market. The Federal Ministry of Education and Research (FMER) is funding the project for three years with three million euros.
