When the sludge is dehydrated by a belt filter press, decanter or filter press, it might be necessary to use lime and convey it to storage (bin, area, silo, etc.). Sodimate, in addition to its quicklime discharge and metering installations and the twin-shaft mixer MBV, designs sludge handling and conveying systems by shaftless screw conveyors in order to be able to supply a complete installation.
The CS screw conveyor is composed of a power source, a trough in stainless steel 304 or 316 (Trough in rolled sheet metal without possibility of clogging unlike a trough made in folded sheet metal) with removable bolted lids, UHMWPE liner (very high abrasion resistance) and a shaftless spiral. Several conveyors in a series make it possible to carry out more complex paths (transfer, elevation, chute, etc.) to convey both limed and non-limed sludge.
