Reverse demulsifier compatible with discharge to sea ?

[SILVERSTONE]

Dear sirs,

I'm presently working on a new installation in Africa dedicated to treat (de-oiling) the process water coming from the oil production.
After having been treated (in order to reach a residual 15 ppm oil concentration) this water is directly discarded into the sea (maximum water discharge flowrate = 2000 m3/h).

A major point is that, in the treatment process, we have to use a reverse demulsifier (deoiler)which will be injected in the process water (normal concentration = 25 ppm, maximum concentration = 50 ppm).

My question is : does an "ecological enough" reverse demulsifier exist to allow the direct discharge into the sea ?

I thank you all for your attention.

Best regards,

I wouldnt ask this question if I dont have at least 36months income protection included in my insurance policy.
