TL;DR: In this article, the performance of an 8-l flat plate solar bioreactor operating in outdoor conditions was investigated, where different organic acids were used as carbon sources (malate, lactate and acetate) and olive mill waste water was used as a sole substrate source.

TL;DR: The feasibility of a new concept of wastewater treatment by combining a membrane bioreactor and a microalgae membrane photobioreactor (MPBR) is assessed, and the MPBRs demonstrated their superiority by limiting the algae wash-out, thus increasing the allowable optimum dilution rate (Dopt).

TL;DR: Results demonstrate that in situ nitrification is feasible in an aerated solid waste environment and that the potential for simultaneous nitrification and denitrification (even under low biodegradable C:N conditions) in field-scale bioreactor landfills is significant due to the presence of both aerobic and anoxic areas.

TL;DR: In this article, the performance of a submerged membrane bioreactor with gravitational filtration was evaluated using a pilot-scale plant and raw domestic wastewater, where treated water was filtered through flat microfiltration membrane modules (polyethylene; pore size 0.4μm) by the pressure head of bulk solution.

TL;DR: An unprecedented approach to PHA production was chosen in the presented work using a multistage system consisting of five continuous stirred tank reactors in series (5-SCR), which can be considered as a process engineering substitute of a continuous tubular plug flow reactor.
Abstract: Poly(hydroxyalkanoates) (PHAs) constitute biodegradable polyesters and are considered among the most promising candidates to replace common petrochemical plastics in various applications. To date, all commercial processes for PHA production employ microbial discontinuous fed-batch fermentations. These processes feature drawbacks such as varying product quality and the inevitable periods of downtime for preparation and post-treatment of the bioreactor equipment. An unprecedented approach to PHA production was chosen in the presented work using a multistage system consisting of five continuous stirred tank reactors in series (5-SCR), which can be considered as a process engineering substitute of a continuous tubular plug flow reactor. The first stage of the reactor cascade is the site of balanced bacterial growth; thereafter, the fermentation broth is continuously fed from the first into the subsequent reactors, where PHA accumulation takes place under nitrogen-limiting conditions. Cupriavidus necator was used as production strain. The focus of the experimental work was devoted to the development of a PHA production process characterized by high productivity and high intracellular polymer content. The results of the experimental work with the reactor cascade demonstrated its potential in terms of volumetric and specific productivity (1.85 g L−1 h−1 and 0.100 g g−1 h−1, respectively), polymer content (77%, w/w) and polymer properties (Mw = 665 kg/mol, PDI = 2.6). Thus, implementing the technology for 5-SCR production of PHB results in an economically viable process. The study compares the outcome of the work with literature data from continuous two-stage PHA production and industrial PHA production in fed-batch mode.
