Yep, the brine is only concentrated by a factor of about three, so it very rapidly dilutes near to the discharge point. Environmental "concerns" like brine discharge are frequently raised without any reference to the quantitative scale of the impact. Desal plant brine discharge is a highly localised environmental impact. There's an odd bias we have where highly localised environmental impacts are readily accepted when they're visually obvious (a car park eradicates all life in the area of the car park), but when it comes to the open ocean, a localised impact is not accepted.
