Biological wastewater treatment and bioreactor design: a review

WebbA slurry is a mixture of denser solids suspended in liquid, usually water. The most common use of slurry is as a means of transporting solids or separating minerals, the liquid being a carrier that is pumped on a device such as a centrifugal pump. The size of solid particles may vary from 1 micrometre up to hundreds of millimetres . Webb1 jan. 2014 · This defined mixed culture was able to grow in slurry bioreactors with or without stimulation, in the presence of MTX and also to remove it from stimulated and non-stimulated bioreactors.

WebbSlurry bioreactors are one of the most highly constructed bioremediation systems available, as well as one of the most effective ex situ solutions for treating polluted soils with resistant contaminants in a controlled setting.

WebbSlurry reactors are three-phase reactors, meaning they can be used to react solids, liquids, and gases simultaneously. They usually consist of a catalyst (solid) suspended in a liquid, through which a gas is bubbled. They can operate in either semi-batch or continuous mode.
