The largest integrated pressurized ultrafiltration (UF) and reverse osmosis (RO) municipal water production plant in Spain, Maspalomas-I in Gran Canaria, has seen both its efficiency and sustainability increased considerably due to installing a Dow ultrafiltration pretreatment. Developed by Dow Water & Process Solutions the compact UF trains are easier to transport than the sand filters previously installed.
This results in reduced transportation cost and lower system footprint for the whole plant, generating economic savings in the installation. The Maspalomas-I desalination plant was built in 1986 as a solution to growing water scarcity issues generated by increased demand from tourism and agricultural activities. Originally it featured electrodialysis reversal technologies that were replaced by Dow reverse osmosis membranes in 2006
