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

These data are given for information purpose only. They are subject to modifications depending on the water quality.

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