The OXERAM projects aim at the development of a cost and energy efficient advanced tertiary wastewater treatment for disinfection and advanced phosphorus removal. The most sustainable solution for meeting the goals of the Water Framework Directive and to ensure the bathing water quality in Berlin surface waters will be identified.

OXERAM 2 is a long term project which will include the assessment of pre-ozonation as pre-treatment to reduce membrane fouling and the assessment of the disc filter technology for advanced phosphorus removal. Additionally the sustainability of different processes for advanced wastewater treatment such as rapid filtration, membrane filtration, UV disinfection and ozonation will be evaluated in OXERAM 2.

The goals of OXERAM 2 are:
