Double pass RO

Double pass RO can supply water qualities with conductivities below 5 µS/cm by treating the permeate water from the first RO in a second RO.

The design and selection of components ensure you a reliable operation with a RO unit that require minimum of maintenance.

Hygienic barrier

A double-pass reverse osmosis plant provides double security against penetration of germs and bacteria in accordance with the US pharmacopoeia.

Bacteria are well controlled since the water is treated through membranes in two stages, each of which is a hygienic barrier.
