The SWD (Westfalia Separator ® 

### SeaWater

Distiller) is working on the well known vacuum distillation principle. Waste heat from the main engine on board is utilized as heating medium for evaporation. The evaporation takes place in the evaporation plate bundle located in the lower part of the housing.

A part of the incoming sea water evaporates due to the high vacuum inside the hous

ing. The generated vapour is cleaned from sea water droplets while flowing through a wire mesh demister. The condensation takes place in the condenser plate bundle located in the upper part of the housing. The condenser is cooled by sea water.The latent heat from condensation is transferred to the sea water. The condensation / evaporation temperature varies with the sea water temperature.

A small portion of the heated sea water is utilized as feed water for the evaporator bundle. The biggest part is used as driv

ing medium for the combined air - / brine Thermal oil / hot water heated Heat exchanger

ejector. This ejector has a double func

tion: Extraction of the surplus sea water (so

condensable gases.

The distillate quality (salinity) is moni

tored at the control panel. If the salinity exceeds the adjusted set point (2 – 10 ppm) the distillate is rejected back to the evaporator via a solenoid valve.

# 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 CO 2 

### 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 corrosion­ and 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.
ApplicationAQUA uses vacuum distillation to convert seawater into highquality fresh water for domestic and process utilization. Byproviding 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 CO 2 

### emissions. • 3-in-1 plate technology. AQUA incorporates the evaporation,separation and condensation processes into a single type of titanium plate. Desalination is handled within a singleplate pack that also contains the process vacuum. No outer shell is necessary. • Simple, compact installation. With no outer shell and no additional service area, AQUA has a minimal weight and footprint. Assembly can behandled on site and installation is simplified by the ability to use smaller seawater pumps and pipes. Since AQUA is not sensitive to roll and pitch, it can also be installed in any direction. • Easy operation and maintenance. AQUA offers start­and­forget operation, which saves time for the crew. Maintenance intervals are long and the plate pack slides open for easy access to the interior. • Proven technology. AQUA has been thoroughly tested in full scale, both in Alfa Laval’s thermal laboratory and onboard vessels at sea.Roll and pitch tests have been performed to ensure that AQUA can be installed in any direction. • Long product lifetime.High­grade materials that resist corrosion and erosion, including titanium for the plates and other wetted parts, ensure that AQUA will last as long as the ship. • Low-salinity water. The fresh water supplied by AQUA hasa lower content of salt and other dissolved solids than that supplied by other freshwater generators. It can be used directly by the steam boilers. • Continuous quality control. AQUA’s salinometer­equipped control system continuously monitors the quality of the outgoing fresh water.

Basic equipmentThe AQUA freshwater generator consists of a single plate pack containing a flexible number of titanium process plates. These plates are suspendedwithin a frame, which comprises a carrying bar, frame plate and pressureplate. Evaporation, separation and condensation all occur within the same plate pack. Among the plate pack features are gaskets with rubber flaps that indicatecorrect plate assembly, as well as distance pipes that ensure proper plate alignment and correct tightening.Connected to the plate pack is a combined system for feed water, condenser cooling water and ejector water. Thefreshwater system consists of a freshwater pump and a freshwater control sensor that ensures a stable outgoing flow. Build­on control panel Support column Carrying bar

### Operating principle AQUA’s flow of feed water is taken from the flow of seawater coolant.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	middle	(separator) section of the plate pack, where any droplets of entrained seawater areremoved. Gravity causes these droplets to fall back into the brine sump at the bottom of the freshwater generator. Only clean freshwater vapour reaches the	top	(condenser)	section	of	the	platepack, which is cooled by a flow of seawater. Here the vapour is condensed into fresh water, which is pumped out of the freshwater generator by the freshwater pump. Evaporation, separation and cooling in the AQUA freshwater generator.



### Installation AQUA is easily installed on ships andrigs, as well as in remote onshore locations. Since there is no need for an extra service area, the installation is highly compact. All maintenance areas can be accessed from within the AQUA footprint	(see	green	diagram). The heating medium is either engine jacket cooling water or a closed circuit heated by steam. An ejector pump supplies seawater coolant for the condenser, feed waterfor evaporation and water for the combined brine/air ejector. This pump is separately installed and connected to its own seawater intake. The fresh water produced is pumpedinto the storage tank by a built­in freshwater pump. A control panel, which incorporatesmotor starters and a salinometer, supplies electrical power to the ejector and freshwater pumps, as well as control voltage to the salinometer and dump valve.

# E asy I nstallation an d O peration

T he dosing/chlorinating unit is meant to dose a chemical into water. T he chemicals can be chlorine for fresh water systems, corrosion inhibitors for main engine cooling water, p H adjustment of fresh water etc.

The unit consists of a dosing pump, a control cabinet, an injection valve and a container for the chemical. The container is equipped with a low-level alarm which stops the pump in case chemical runs out, a suction valve and a manual agitator. All components are mounted on a stable steel frame for easy installation.
The most common application is that the dosing unit is being used to prechlorinate or pH-adjust fresh water, prechlorinate evaporated water or bunker water, on its way to fresh water holding tank, and to rechlorinate water before it is distributed. The prechlorination systems are normally controlled by flow meters in bunker water flow line and evaporated water flow line respectively. This ensures enough chlorine dosed into the actual water flow in the water line proportionately.

# For f re s h wa ter di s in f ection

Sterilizing drinking water with silver is a very old method and has been adopted frequently in many parts of the world. As a matter of fact, this method goes back to antiquity.
Disinfection of water by dosing silver ions into water is completely harmless to human as well as animals. The amount of silver ions in the disinfected water is well below the maximum amount stated e.g. in the directives issued by the WHO.
Silver ions do not change the taste, smell or colour of the water. Nor do they effect the physical and chemical properties of the water. The silver ions only kill off bacteria, germs, algae etc. JOWA Ag-S is well-known to the shipping industry. Many thousands of ships have had it installed onboard since its introduction in 1970. Due to its simple design and high quality, the first installed units are still in operation, only periodical replacement of the electrode is needed.

The JOWA Ag-S comes as one unit ready to be fitted onto the bulkhead. It consists of an electronic cabinet, an electrode chamber with two shut-off valves, a flow setting valve and a pressure gauge. All these parts are mounted on a common electropolished stainless steel base plate. A flow switch is also installed.
