RO concentrate treatment

What we can du with RO is an effective technology for brackish water treatment. Unfortunately, the concentrate makes the application of this technology difficult in agricultural applications.
Is there any positive experience for RO concentrate removal or treatment.

1. Advanced membrane treatment technologies that are used to do this include reverse osmosis (RO) and ultrafiltration (UF).Numbers of brackish water reverse osmosis desalination plants to be built in this regards and solve the problems. The simplest approach to disposing of RO concentrate is to blend it with municipal wastewater effluent, resulting in a smaller discharge volume containing nearly the same mass of contaminants.The concentrated waste stream resulting from RO treatment can pose chronic ecotoxicity risks if discharged to surface waters or shallow coastal ecosystems. Most existing RO concentrate treatment technologies are cost prohibitive, but constructed wetlands hold promise as a viable multibenefit solution because they have the potential to provide simultaneous treatment of nutrients, metals, and trace organic contaminants at a relatively low cost. They also are popular with the public. A handful of water-stressed cities have already begun experimenting with constructed wetlands for RO concentrate treatment. RO concentrate management approaches may differ between coastal and inland locations, so we considered the discharge strategies and implications of RO concentrate discharge in both settings.
