The INPORR project promotes innovative solutions that fit into the concept of a circular economy. The project received funding under the Small Grant Scheme competition (SGS, https://www.gov.pl/web/ncbr/small-grant-scheme-2020-call), which is part of the "Applied Research" Program, financed by the Norwegian Funds and Funds European Economic Area (EEA).

The aim of the INPORR project is to create an integrated technology that enables both the removal and recovery of nutrients (nitrogen and phosphorus) in municipal wastewater treatment plants.

The INPORR project will be divided into work packages involving themes associated with the basic research about nitrogen recovery in a gas permeable membrane reactor (WP1), experimental research on INPORR technology (WP2), and the model-based evaluation of the technology for nitrogen and phosphorus removal and recovery (WP3).

The project includes the following specific objectives (investigated under specific work packages (WPs):

  1. Basic research of nitrogen recovery in a gas permeable membrane reactor (GPMR) (WP1). Aiming at experimentally determining the reactor operating parameters, such as acid flux, operating pH, hydraulic retention time and effective membrane surface.
  2. Experimental confirmation of the effectiveness of the proposed INPORR technology in terms of nitrogen and phosphorous removal and recovery. Conducting analytical and laboratory experiments to confirm the predictions of scientific research of both selected elements and the entire technology (WP2).
  3. Development and evaluation of a mathematical model of the proposed INPORR technology. Validation of the obtained results in the environmental conditions (data from the experiments in which the laboratory scale prototype set-up will be located in the WWTP and operated using sludge digester liquors) (WP3 Task 3.1).
  4. Model-based evaluation of the proposed technology with respect to nutrients recovery potential, energy consumption and the carbon footprint (WP3 Task 3.2)
