摘要：
A process treats production water resulting from enhanced oil recovery, the production water comprising an aqueous phase and an organic phase dispersed in the aqueous phase, and at least one polymer in the aqueous phase. The process includes:
a step of bringing said production water into contact with an additive comprising at least one tetrakis(hydroxymethyl)phosphonium salt (THMP salt),
a step of separating the aqueous phase and the organic phase of said production water comprising said additive, by means of a hydrocyclone.
An enhanced recovery process uses a step of treating the production water according to the invention.
a step of bringing said production water into contact with an additive comprising at least one tetrakis(hydroxymethyl)phosphonium salt (THMP salt),
a step of separating the aqueous phase and the organic phase of said production water comprising said additive, by means of a hydrocyclone.
