SWRO plants with 2 passes are also available by adding a BWRO plant in series to further purify SWRO permeate and maximise Boron removal is warm and very salty waters.

Seawater RO units always required a pre-treatment, that's why Lenntech offers large SWRO packages including pretreatment and post treatment.
