This paper discusses the implications that increasing water recovery has on feed water chemistries and how additional pretreatment is required to eliminate specific solute compounds from interfering with reverse osmosis (RO) system separations and efficiency. Examples of actual system designs with specific feed water chemistries are discussed to show the necessary pretreatment steps required to mitigate water chemistry issues in high recovery RO systems.
