AQUA Titanium-plate freshwater generator The AQUA freshwater generator The AQUA freshwater generator is a major advance based on proven Alfa Laval expertise. AQUA’s optimized process cuts seawater needs in half, which minimizes pipework and allows the installation of smaller seawater pumps. This in turn reduces installation costs, fuel consumption and CO2 emissions. AQUA makes use of 3in1 plate technology, which enables desalination in a single plate pack with one type of titanium plate. Since the plate pack also contains the process vacuum, AQUA has no outer shell and is smaller than other freshwater generators. The plate pack slides open for easy access to the interior without an additional service area. The use of corrosionand erosionresistant titanium, combined with an optimized process that inhibits natural scaling, ensures that AQUA needs little maintenance. The system has been fully tested both on and off shore, and is designed to last the lifetime of the ship. Application AQUA uses vacuum distillation to convert seawater into highquality fresh water for domestic and process utilization. By providing a constant supply of lowsalinity water and continuously controlling the water quality, it eliminates the need for bunker water. AQUA is designed for automatic operation in periodically unmanned engine rooms and other automated operations. It is suitable for installation on ships and rigs, as well as in remote onshore locations. Jacket water, steam injection or a Hot Water Loop can all be used as heating media.

Features and benefits • Half the seawater flow. AQUA requires only half the seawater needed by other freshwater generators, which means smaller seawater pumps can be used. Optimized distribution prevents dry spots and inhibits the natural scaling process. • Lower costs and emissions. The reduction in seawater pumping needs has a corresponding effect on the consumption of electrical energy. Less fuel has to be burned, which reduces both operating costs and CO2 emissions. • 3-in-1 plate technology. AQUA incorporates the evaporation, separation and condensation processes into a single type of titanium...

Feed water enters the lower (evaporator) section of the plate pack, in which the plates are warmed by the heating medium. Here the water is evaporated at around 4060° C in a vacuum of 8595%, which is maintained by the brine/air ejector. The vapour produced rises between the plates into the...
