Our solution:

HUBER ROTAMAT® plant for continuous sludge thickening

Thus you achieve:

•    The sludge vo!ume is considerably reduced

•    smali sludge silos, smali digestors

•    effective digeslor operation

•    improved operation of the subsequent sludge dewatering plant

•    Iow transport costs for sludge disposal

Example:

Thickening of excess sludge with 0.5% DS to 6- 12% DS. This corresponds to a volume reduction by 92-96%, i.e. less than '/20 of the initial volume remains.

In a fully automatic coagulant preparing plant,

the powdery or liquid coagulants (polyelectroly-tes) are continuously mixed with water. With a coagulant dosing pump the ready for use coagulant solution is directly dosed into the feedpipe before the flocculation reactor.

Within the flocculation reactor a slowly rotating stirrer favors the flocculation and ensures that on the overflow of the flocculation reactor after an adequate duration only completely floccula-ted sludge can flow into the ROTAMAT-thickening press.

Within the ROTAMAT-thickening press the flocculated sludge is gently tran-sported across a wedge wire. The filtrate is flowing out through the screen.

During operation, brushes in the spirals of the screw as well as interval flushings provide the cleaning of the wedge wire. The thickened sludge is transported with a sludge pump equipped with a sludge storage tank into a digestor or a sludge siło.

HUBER ROTAMAT® plant for continuous sludge thickening - a profitable investment:

• continuous improvement in treatment

•    Iow first cost

•    continuous reduction of operating costs efficiency
