A reactor vessel for use in treating slurries containing minerals, soils or sludges contaminated with toxic organic substances is disclosed. The vessel includes a tank, having a sealed cover, a mixer arrangement, an air supply arrangement and an exhaust gas recycling system. The air supply arrangement includes one or more porous, flexible membrane diffusers adapted for introducing gas, in the form of fine bubbles, into a tank-contained slurry.

Bioslurry reactor for treatment of slurries containing minerals, soils

A transportable apparatus for biological treatment of a slurry of contaminated materials, including a series of square reactor cells having substantially parabolic lower portions, set at the same elevation and communicating in series. Gas diffusers are placed in each cell for aerating and mixing the slurry, and an airlift slurry transport system is employed for recirculating the slurry. The apparatus also has applicability to the treatment of water and waste water.

Multi-cell transportable bioslurry reactor

A reactor vessel for use in treating slurries containing minerals, soils or sludges contaminated with toxic organic substances is disclosed. The vessel includes a tank, having a sealed cover, a mixer arrangement, an air supply arrangement and an exhaust gas recycling system. The air supply arrangement includes one or more porous, flexible membrane diffusers adapted for introducing gas, in the form of fine bubbles, into a tank contained slurry.

A reactor for use in processing metal bearing solids by means of a bioleaching technique is disclosed. The reactor includes an open topped basin, a gantry adapted for displacement along the length of that basin and an agitation means mounted on that gantry for use in agitating a slurry retained within the basin. An air injection system having a plurality of membrane diffusers is positioned within the basin.
