Water Standard partnered with Membrana to pilot the technology in continuous seawater trials. When compared to vacuum towers the system reportedly required 50% less space and weight while providing more efficient oxygen removal.
"The MDA pilot unit produced approximately 5,000 barrels per day of deaerated seawater and operated without chemical oxygen scavenging, scaling or fouling of the membranes for an extended period, said Lisa Henthorne, Water Standard's CTO. “The pilot evaluated operating and design parameters such as seawater flow rate, level of pre-filtration, and nitrogen sweep rate. Throughout pilot testing, the MDA unit consistently achieved less than 10 parts per billion (ppb) of dissolved oxygen in the treated water without chemical addition. This compares very favourably to vacuum towers, which normally achieve 50-100 ppb and require additional oxygen scavenging chemicals."
