Abstract
A drilling mud treatment unit () comprises a primary duct () for feeding coagulated drilling mud, an in-line flocculation system () for flocculating the coagulated drilling mud flowing in the primary duct (), and at least one hydrocyclone () fed by the primary duct () and arranged downstream from the flocculation system (). The hydrocyclone () has an overflow orifice () for receiving a liquid product resulting from treatment of the drilling mud and an underflow orifice () for receiving a solid product resulting from treatment of the drilling mud. The overflow orifice () presents an overflow diameter (Do) and the underflow orifice presents an underflow diameter (Du), and the underflow diameter (Du) is greater than 1.1 times the overflow diameter (Do).
