Liquid purified by sedimentation is suctioned off from the upper end of the sedimenting vessel by means of a jet pump (28).

The three bioreactors (10, 11 and 12) and the settling device (17) are housed in a tank having three sets of vertically-staggered transverse partitions (21, 22, 23) and a transverse settling tank partition (24).

A sedimentation separator for separating solids fractions from a mixture consisting of air, liquid and solids fractions comprises a sedimenting vessel (44) to which an air-separating unit (16) is connected upstream.

In a second step, the carbohydrate slurry stream is held in a settling tank to remove a further portion of the fiber.

In a preferred embodiment the degassing chamber is combined with and works in conjunction with a sedimentation tank to provide an efficient clarification station.

Chemicals must sometimes be mixed into the activated sludge before it enters the secondary sedimentation tank.

Chemicals must sometimes be mixed into the activated sludge before it enters the secondary sedimentation tank.

When the waste water containing aggregated impurities is filtered through a filter (18) arranged in a sedimentation/filtration tank (17), impurities in the waste water are removed thoroughly.

When the tank sedimentation tank is frozen, it is prohibited to roast with fire, hot water, steam melting, or the car into the greenhouse thaw.

A condensation-system (liquid or/and solid) material (5) comprising the two or more isotopes is placed in a sedimentation tank (for example, (2)) which is then housed in a supercentrifuge.

The device for implementation of the process described in the invention consists essentially of a settling tank with an overflow into which projects a vibrator immersed in the sludge, separating the solid from the liquid phase.

Located below the clarification region is a perforated or mesh-type plate which partitions off, in the settling tank, a flow area, which is provided with a connection for the introduction of the hot gas or hot air.

The sludge will become putrescent in a short time once anaerobic bacteria take over, and must be removed from the sedimentation tank before this happens.
