Cost and Energy Saving Processes for Tertiary Wastewater Treatment Steps (Preparatory Phase: OXERAM-1)

Optimization of flocculation for tertiary filtration processes and evaluation of sustainability of tertiary wastewater treatment

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-1 is the preparatory phase for a larger 36 months project (OXERAM 2) which will include the assessment of pre-ozonation as pre-treatment to reduce membrane fouling and the assessment of the Discfilter® 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-1 are

  • The extension of the budget for OXERAM-2 by applying for funding
  • Definition of the long term research program
  • Technical design and project planning for OXERAM-2
  • Preparation of the necessary analytical tools


Selected publications produced in the OXERAM 1 project are available here .
