Can You Use A Centrifuge To Clean Produced Water?

By using a 3-phase centrifuge, the client can speed up their ,oil, recovery process much faster than your typical ,separation, using tanks this allows them to process more incoming produced water which gives them the water they need to frac the next ,well,. If they cannot treat water fast enough then they must buy water from other sources.
