... of this work the feasibility of successfully operating a compressor-less, efficient, compact deaeration system on positive pressure. Additionally, the stripping gas technology requires no chemical scavengers in order to obtain an oxygen concentration lower than 10 ppb. The membrane deaeration process can also...

... demonstration plant was run on high total suspended solids seawater over a period of 6 months. Outlet dissolved oxygen concentrations were in the order of 2.5µg/l (ppb). The performance of key components of the system is described, including: ultrafiltration membrane pre-treatment under extreme solids loading...

... be intensified and prolonged by the intrusion of high salinity bottom water from a Loop Current eddy. In 1978, a widespread low oxygen layer occupied the lower 3 to 8 m of the 6 to 17 m water column for at least 3 weeks. Dissolved oxygen concentration was commonly less than 0.1 ppm in this layer, resulting...
