This study proposes the integration of a new P-recovery strategy through the use of a side stream enhanced biological P removal (S2EBPR) process. To evaluate this alternative, a 150 L pilot-scale anaerobic/anoxic/aerobic (A2O) plant was operated with a side-incorporated reactor (10 or 23 L) to work as an anaerobic side stream sludge fermenter (SSSF).

Energy produced from renewable sources such as sun or wind are intermittent, depending on circumstantial factors. This fact explains why energy supply and demand do not match. In this context, the interest in biomethanation has increased as an interesting contribution to the Power-to-gas concept (P2G), transforming the extra amount of produced electricity into methane (CH4).

In this study, a modular, multi-step, photometric microflow injection analysis (micro-FIA) system for the automatic determination of Cu(II) in a bioreactor was developed. The system incorporates diverse 3D-printed modules, including a platform formed by a mixer module to mix Cu(II) with hydroxylamine, which reduces Cu(II) to Cu(I) linked to a diluter module via a Tesla valve, a chelation mixer module, a disperser module, and a detector module provided by an LED light source at λ = 455 nm and a light dependence resistor (LDR) as a light intensity detector.
