OPERATIONS MANAGEMENT


EXAMPLE OF SLUDGE DEWATERING WITH JVK TCM/TCC PLATES Here is an example of an effective vacuum drying process for communal sewage sludge with a high organic content. The process steps come from a sewage sludge with additional biologic treatment (polymer conditioning), first with a squeezing pressure of up to 40 bar followed by a vacuum drying time of 150 minutes. The finished drying process with the same sludge, a high sand content and no treatment at all is also illustrated.


EXAMPLE OF A PROCESS DIAGRAM FOR A TCC/TCM DRYING SYSTEM In this filter process, a TCC plate related to steam of 110°C and the TCM plate was used with hot water of 75°C. A dry solid concentration (green) of almost 100% was reached using only a constant vacuum (blue). The squeezing pressure of the TCM plates was sequentially set up and the TCC pressure was also constant due to a permanent heating flow.
