30 Maritime Reporter & Engineering News CWWS Ultra-SEP Bilge Water Separators Dual Stage Ultra-SEP Bilge Water Separators are designed to optimize per- formance in both processing phases for separating and removing free and emul- sified oils from bilge water. The first stage efficiently removes free oils using our HELI-SEP coalescing separator. The second stage - the critical component for satisfying IMO MEPC.107 (49) regula- tions for treating emulsified oils uses proprietary Spir-o-Lator ultra-filtration membranes. Ultra-SEP is available in eight models with capacities ranging from 0.25 cu. m./hr to 10 cu. m./hr. Circle 54 on Reader Service Card NEI's Venturi Oxygen Stripping System NEI offers its Venturi Oxygen Stripping system, a patented system that is designed to simultaneously treat ves- sel ballast water while protecting the ballast tanks against corrosion. As the ballast tank begins draining, the inert gas generator turns on, and very low- oxygen is introduced into the top/void space of the ballast tank. As the ballast tank drains, the inert gas fills the void space, providing an inert gas blanket throughout the tank, a low-oxygen con- dition which is monitored and main- tained throughout the voyage. Just before the ballast tanks are filled, the inert gas generator turns on. As water comes into the vessel, very low-oxygen gas is mixed into the ballast piping at a preset ratio. Dissolved oxygen is low- ered to a hypoxic treatment level in less than 10 seconds, and biological treat- ment begins immediately. The ballast tanks fill with deoxygenated water, and treatment is complete in 48 hours.

Y Marine Environment Oil-Xorb ERC The OIL-XORB ERC compound is a water-activated surfactant that separate emulsified oil from water. The com- pound has a strong chemical affinity for water, and will preferentially absorb and dissolve the water emulsi- fied in the grease, oil or grime that the compound is used to clean or separate. Oil-Xorb ERC is a surfactant system. It is biodegradable, non-flammable, non-toxic at use concentrations and is both hydrophilic (water-attracting) and oleo-phobic (oil-repelling). It thus is designed to offer excellent emulsion- breaking capability in addition to its performance as an agent for cleaning both metallic and non-metallic sur- faces. The strong chemical affinity of the Oil-Xorb ERC systems for water and the high surface energy at the Oil-Xorb ERC/hydrocarbon interface results in rapid extraction of the water from the emulsified oil, leading to a complete separation of uncontaminated oils and greases (these are now of lower densi- ty because the water has been removed) on the top, the Oil-Xorb ERCsystem in the middle, and precip- itated solids on the bottom. The compounds will maintain the separation, and can be re-used until the formulations have biodegraded to the point where their utility is lost, usually in 30 to 45 days, without any effects to the bio-environment. The Oil-Xorb ERCsolution in most cases also removes loose corrosion (rust, scale) from metal surfaces and leaves a paintable surface protected by an inorganic micro-layer that reduces subsequent scale build-up. • Oil-Xorb ERC is non-flammable. It separates solids and water from crude oil. It is non-toxic and low foaming. It biodegrades in 30-45 days after activation with fresh or salt water. It is a mild de-emulsifier.
