Is it possible to use the residual pressure from the reverse osmosis concentrate stream to directly discharge the concentrate into other devices for further treatment?

Currently, the pressure of the reverse osmosis concentrate stream is relatively high; the conventional approach is to discharge this concentrate into the wastewater stream and then pump it to other systems for further treatment. Is it possible to utilize the residual pressure of the reverse osmosis concentrate stream to convey it through 1,000 meters of piping to other devices for further treatment? With such a long pipeline, it is unclear whether it will cause unstable operation of the reverse osmosis system and lead to secondary problems.
If the pressure on the concentrated water side is above 2 kilograms, there is no need to worry about transportation issues; however, it becomes somewhat difficult when the pipe height exceeds 10 meters.
Our company specializes in reverse osmosis brine recovery; by utilizing the high pressure of the brine, we manage to recover energy while also reducing the amount of brine discharged, with a brine utilization rate of 50%
We use all of this concentrated water as recycled water.
The pressure of the concentrated water has been increased, which to some extent improves the water production rate; I’m not sure though if this will reduce the desalination efficiency~
