On the basis of the demand of ÚJV Řež, a.s., the removal and treatment of contaminated chemical sludge from the sedimentation tank of the WWTP on the premises of ÚJV Řež, a.s. was carried out in the period from December 2021 to March 2022. The contract included the extraction and subsequent treatment of sludge by solidification from the 33 m3 sump.

The sludge was extracted by a sludge pump with a crusher and then dewatered by means of a decanting centrifuge, whereby the volume of the pumped sludge was thickened to a dry matter content of 40% on average. The result of the centrifugation was 76 drums with 9.8 tonnes of thickened sludge, which was further processed by the solidification method.

Well done!
