Fluidized bed bioreactors (FBR) are characterized by two-phase mixture of fluid and solid, in
which the bed of solid particles is fluidized by means of downward or upward recirculation …

In a membrane bioreactor (MBR), fast growth of anammox bacteria was achieved with a
sludge residence time (SRT) of 12 days. This relatively short SRT resulted in a—for …

Biofuel cells have been widely used to generate bioelectricity. Early biofuel cells employ a
semi-permeable membrane to separate the anodic and cathodic compartments. The impact …

There is a need for alternative catalysts for oxygen reduction in the cathodic compartment of
a microbial fuel cell (MFC). In this study, we show that a bipolar membrane combined with …

The oxygen reduction rate at the cathode is a limiting factor in microbial fuel cell (MFC)
performance. In our previous study, we showed the performance of an MFC with ferric iron …

Nitrospiraceae is the only established family in the phylum Nitrospirae and comprises the
genera Nitrospira, Leptospirillum, and Thermodesulfovibrio. In phylogenetic trees based on …

The Ferredox process is a biohydrometallurgical concept flow sheet targeting tropical
limonitic laterites. The process components are designed to (a) facilitate simplified and low …

The aim of this study was to study and model the bioleaching of abandoned mine tailings at
different pulp densities 1–20% w/v by using an autochthonous mesophilic microbial culture …

Ferric iron is a low-cost oxidant frequently used in hydrometallurgy and is particularly
suitable to leach various metals from printed circuit boards (PCBs). This paper presents the …

The aim of this work was to evaluate the feasibility of the use of different industrial and
agricultural wastes as reactive materials in Permeable Reactive Barriers (PRB) for Acid Mine …
