TL;DR: In this paper, a method of producing fuel from biodegradable carbonaceous material using a stacked particle bioreactor is provided, which is formed from particles including bio-degraded material.
Abstract: A method of producing fuel from biodegradable carbonaceous material using a stacked particle bioreactor is provided. A stacked particle bioreactor is formed from particles including biodegradable carbonaceous material. The biodegradable carbonaceous material in the stacked particle bioreactor is aerobically and/or anaerobically bioconverted into one or more synfuels, which are collected from the reactor. The synfuels produced by the method may include synthetic petroleum, alcohol, and/or a gaseous fuel containing methane. Preferably the method includes an aerobic biotreatment phase followed by an anaerobic bioconversion phase. A stacked particle bioreactor for carrying out the anaerobic, and preferably aerobic, degradation is also described.

TL;DR: Anaerobic treatment of wastewater and waste organic solvents originating from the pharmaceutical and chemical industries was tested in a pilot anaerobic membrane bioreactor, which was operated for 580days under different operational conditions to test the long-term treatment efficiency and identify inhibitory factors.

TL;DR: The results of this study demonstrate that hydrogen-coupled denitrification can serve as the basis for small-scale remediation and that pilot-scale testing might be the next logical step.

TL;DR: Anaerobic pre-treatment is not feasible and an aerobic system is preferred for the treatment of greywater, which resulted in a COD removal significantly higher than 51% removal by anaerobic treatment.
Abstract: Greywater consists of household wastewater excluding toilet discharges. Three systems were compared for the biological treatment of greywater at a similar hydraulic retention time of approximately 12–13 hours. These systems were aerobic treatment in a sequencing batch reactor, anaerobic treatment in an up-flow anaerobic blanket reactor and combined anaerobic-aerobic treatment (up-flow anaerobic blanket reactor + sequencing batch reactor). Aerobic conditions resulted in a COD removal of 90%, which was significantly higher than 51% removal by anaerobic treatment. The low removal in the anaerobic reactor may have been caused by high concentration of anionic surfactants in the influent (43.5 mg/L) and a poor removal of the colloidal fraction of the COD in up-flow anaerobic sludge blanket reactors. Combined aerobic-anaerobic treatment accomplished a COD removal of 89%, similar to the aerobic treatment alone. Greywater methanization was 32% for the anaerobic system and 25% for the anaerobic-aerobic system, yielding a small amount of energy. Therefore, anaerobic pre-treatment is not feasible and an aerobic system is preferred for the treatment of greywater.
