Innovative biological wastewater treatment system with functionally differentiated biofilm reactors (IBAS)

The aim of the joint project known as Innovative Biological Wastewater Treatment System (IBAS) is to develop a calculation base for a new biological wastewater treatment system with functionally differentiated biofilm reactors, in order to subsequently bring the process to market. The system will make it possible to almost entirely eliminate nitrogen compounds, as stipulated for sensitive areas by the European Water Framework Directive. The system presents advantages such as the reduction of tank volumes for carbon removal and denitrification, greater stability of nitrification, energy savings with regard to aeration, and low investment costs.

The project, which is funded by the German Federal Ministry of Education and Research, is being implemented by WTE Wassertechnik GmbH in collaboration with Martin Membrane Systems (MMS) AG, the Research Institute for Water and Waste Management at RWTH Aachen (FiW) as well as Abwasserreinigung Dietzenbach GmbH (adg) as an associated member.
