Centralized sludge dewatering was too costly to maintain
The sludge disposal cost was extremely high for this meat processing plant in Ukraine, since they disposed sludge by tanker truck without sludge dewatering. Because of the high sludge disposal cost, they had been looking for a sludge dewatering equipment suitable for dewatering oily, fatty and greasy sludge, but could not find a solution.
After a long sludge dewatering technology research, they decided to install VOLUTE™ Dewatering Press ES-303 to handle their oily, fatty and greasy sludge.
Here is the client’s voice:
“We had always been concerned about clogging problems which could be caused by dewatering such an oily sludge. Nevertheless, VOLUTE™ with its high resistance to oily sludge has now been operating without any clogging problems and we are very content with the installation. Now, our operator pays only minimum attention to the equipment because of its fully automatic operation. Overall, the cake dry solids content is always around 29 % and we are very satisfied with the solution which VOLUTE™ Dewatering Press brought to us.”
