Each year, GN Solids Control produces around 150 sets of decanter centrifuges, a certain number among those are used for flocculation systems together with some chemical dosing systems. In some countries and regions, it is compulsive to have a set of flocculation unit and a decanter centrifuge alongside of the drilling rig, in order to treat the drilling fluids on time. And the after treated drilling fluids could flow back to the drilling system.
