Research project PIRAT Systems

PIRAT-Systems - Process Improvement for Resource-Amended (material, nutrient and energy-efficient) Treatment Systems

PIRAT-Systems is a research project coordinated by the department of Resource Efficient Wastewater Technologies at the Technical University of Kaiserslautern. The project takes place within the scope of the project CLIENT II China funded by the German Federal Ministry of Education and Research.

The project period is set to be 01.09.2018 - 31.08.2021.

Wastewater disposal is currently undergoing a paradigm shift from a disposal management to a resource-oriented approach, where important wastewater components are recovered and reused, and energy consumption is reduced. While initial approaches regarding these topics are already being implemented in Germany, further development and adaptation of system components and concepts is required worldwide. The PIRAT Systems project follows the approach of an interdisciplinary teamwork of German and Chinese players (consultants, construction companies, fertilizer processing companies, operators, government agencies and research institutes) to develop selected technologies for the Chinese market and to elaborate, based on investigations on model-wastewater treatment plants (model-WWTP), concepts for increasing energy efficiency and integration of sustainable components. In order to be able to transfer the results of the investigations on model-WWTP to other plants within and outside of China, design approaches and simulation models will be developed as planning tools as well as decision-making guides. As a result, suitable operating settings and instrumentation, control and automation (ICA) strategies for an integrated operation of the system components can be determined for various boundary conditions and transition paths can be evaluated. In close cooperation between the German and Chinese partners, implementation and application of the results on WWTP in China are demonstrated. The next step will be to expand the system boundaries through examination of market options for recycling products. The treatment options and possibilities of feed-in of biogas into the natural gas network are proved. Promotion and inhibitory factors for application, including acceptance among the population, are identified. The overall goal of the project is closing the material and nutrient cycles while maintaining an extremely good cleaning performance of WWTP to meet the strict Chinese boundary values and the improvement of the environmental situation (climate protection, reduction of emissions, protection of water, air and soil).
