Optimization of centrifuge operations is a final critical step to cost control and dewatering sludge.
The key components to ensuring stable operation, maximizing cake solids and minimizing polymer usage are to have effective measurement of process parameters and the ability to regulate the operation.

Process Measurement:
  • Inlet solids – metsoTS microwave solids transmitter
  • Inlet flow – appropriate flow meter
  • Polymer flow – appropriate flow meter
  • Filtrate solids/turbidity – metsoLS
  • Centrifuge Load (amps)
Control Parameters:
  • Centrifuge speed – if variable
  • Inlet flow – control throughput with a valve or pump
  • Polymer rate of addition – to maximize filtrate clarity, cake solids
The more uniform the solids feed into the centrifuge, the more stable is the centrifuge operation and higher throughput can be obtained at a consistently high cake solids.
Polymer addition is required to get good water removal from the feed sludge but polymer addition has a point of diminishing returns where the more that is added, the less effective it is at flocculating the solids and enabling the centrifuge to produce the desired solids in the cake.
