EcoStream Oily water cleaning system - 1

Oily water cleaning system EcoStream oily water cleaning system. Towards cleaner oceans Bilge water generated onboard ships is a major environmental concern for the shipping industry. Regardless of its source, bilge water must be treated to reduce the oil content to levels that meet international regulations for release into the environ- ment. This is critical to keeping the world's oceans and their vast marine ecosystems healthy and productive. The impact of ship propulsion on the marine environment can be minimized and heavy fines avoided if efficient bilge water treatment is carried out onboard. The need for waste disposal ashore can also be reduced. Over the years, the cost for waste disposal has continued to climb as local authorities enforce stricter laws for the land-based companies that process this waste. Cleaning bilge water poses distinct challenges. Not only does the composition and flow of bilge water change, making con- tinuous and efficient treatment difficult, but treatment onboard presents another set of constraints. Treatment methods must meet individual ship requirements and demands for safety, reliability, compactness, automation, low maintenance and the ability to withstand rough weather Centrifugal separation has proven to be a reliable, efficient and flexible method for continuous removal of oil and other contaminants suspended in the bilge water onboard ships and at land-based power plants.

EcoStream Oily water cleaning system - 2

EcoStream: Reliable, efficient, The Alfa Laval EcoStream solution Is a reliable single-stage centrifugal separa- tion system for highly efficient treatment of large bilge water volumes at sea as well as ashore. The compact modular system generally cleans bilge water to less than five parts per million (ppm) oil Based on a standardized concept, EcoStream is a complete stand-alone system that Is easy to install for any new or existing Installation. Continuous, fully automatic operation - even when subjected to oil shock and rough weather conditions - reduces the need for large bilge water...

EcoStream Oily water cleaning system - 3

Bilge water Bilge water can be a mixture of water, fuel oil, lube oil, hydraulic oil, deter- gents, oil additives, chemicals, catalytic fines, soot and other substances. This mixture Is normally collected In a bilge water settling tank and maintained at The marine sector uses large amounts of chemicals for cleaning, service and maintenance activities in the engine room and many of these products are surfactant-based. As such, these chemicals contribute to emulsion for- mation in a ship's bilge water system. water, where small oil droplets are dispersed In the continuous water Separation...
