Desalination pre-treatment

Polymem Ultrafiltration is the ideal pretreatment to desalination or demineralization by reverse osmosis on spiral wound membranes for demineralization or desalination. Ultrafiltration placed upstream of seawater reverse osmosis allows:

– To save about 20% on the design of reverse osmosis
– To significantly reduce the reverse osmosis membranes replacement frequency
– To decrease reverse osmosis system energy consumption of about 10%
– The protection and sustainability of the reverse osmosis system

Modules to use for desalination and demineralization pre-treatment: RANGE ULTRAMEM and GIGAMEM®
