NanoH2O membranes chosen for Canaries SWRO retrofit

High-rejection QuantumFlux seawater reverse-osmosis (SWRO) membranes manufactured by NanoH2O Inc have been chosen to retrofit one of two first-pass trains at the Puerto del Rosario IV desalination plant located on Fuerteventura, one of Spain’s Canary Islands.

Puerto del Rosario IV, owned and operated by Consorcio de Abastecimiento de Aguas a Fuerteventura (CAAF), is an expansion of the original seawater RO plant built on the island in 1998. NanoH2O‘s membranes will produce an estimated 6,500 m³/d of water, making this facility one of the company’s largest installations in the Canary Islands.

The membranes will be delivered to Puerto del Rosario IV by contractor Degrémont.

“NanoH2O provides us the opportunity to save significantly,” said Andres Rodriguez, production manager at CAAF. “NanoH2O’s membranes will allow us to use fewer elements, operating at the same pressure and producing very good water quality with low boron content.”
