Overview

FUCO-HEG produces and supplies the frequently tried and tested purification and thickening plant (solid separator – system Dr. Kronenberger – German B.P. 3215033.4) for slop purification and sludge drainage (now more than 300 installations).

Output:
2 – 200 m3 / h per unit

Slop purification:
waste water can be purified impeccably with the solid separator shown opposite, e.g. from

concrete plants, ceramic companies, natural stone companies, gravel washing, foundries, electro-plating shops, battery productions, etc.

and processed for a circular flow operation or for discharging into the canalisation network or a receiving stream.
The good separating effect is due to the fact that the slop already flows very slowly when it enters the separator owing to the large distribution over the whole extent and shortly under the water surface has reached a speed of just a few mm/sec.
The slow-moving rabble rake installed in the separator ensures that no sludge is deposited on the cone walls so that impeccable removal of sludge ? either by the hydrostatic pressure or by means of a sludge pump ? is guaranteed at all times.
With the supported neutralisation of the waste water the installation of a ph-value regulation is possible without any difficulties by means of a dosing pump. The stirrer required with conventional construction (clarifier) is saved. The same applies if the depositing process of the solid particles takes a long time and for this reason it is necessary to work with flocculation agents. The addition of flocculation agents is carried out in the slop supply line and does not require any further work.

Sludge drainage

The sludge collected in a purification and thickening plant or a digestion tank (municipal clarifier) is extracted daily using a sludge pump, conditioned in a coagulator with flocculation agents and conveyed to the drainage container. Through the conditioning of the sludge it “disintegrates” in the E-Container into “solid flakes” and filtrates. These solid particles, subsequently the filter cake, are retained in the E-Container, while the filtrate passes through the panelling and the perforated sheet metal base and flows off. The drainage of the sludge can also be carried out in a filter press whereby up to 80{06105e1b926b51a75442da20d15ea774720d2c2f85a02c49b0909e09a6ae2ac9} dry substance is achieved in the filter cake.
