Desalination unit for sea water

Inverse osmosis plant – Desalination unit for sea water

Prikaz postrojenjaSkid mounted orcontainerised reverse osmosis desalination plants that are able to produce fresh water for potable or technical purposes.

Seawater reverse osmosis desalination plants are designed to produce drinking water (salt content less than 500 ppm) from a seawater feeding with salinity up to 55000 ppm and capacity up to 5000 m3/day.

The end user shall only connect seawater feeding header, product water outlet header and brine outlet.

The plant is fully automatic to ease the operation of the end user.

All the materials are selected to guarantee the longest lifetime of the package and to minimize the routine maintenance; as an example, the seawater pipes under high pressure are manufactured in Duplex stainless steel, while those under low pressure are made in atoxic PVC.

Each reverse osmosis plant is equipped with CPI (Clean In Place) system for periodical membrane cleaning.
