Hydrocyclone design have one drawback that is the rigidity. A design is specific to the flowrate and all the condition where the inlet composition is fixed.

Here the Cluster of Hydrocyclone is useful. A cluster offers the flexibility in the input flowrate. As per the requirement one should choose the number of Hydrocyclones and operate as many as per the capacity requirements.

Cluster is also useful if there are problems of chokeup which may come about when a large particle enters the inlet choke. With Cluster you can close one Hydrocyclone and attend to it and keep the plant running.
