System description
1.0 WORKING PRINCIPLE
The combined brrnetarr ejector driven by the ejector pump creates a vacuum in the system in order to lower the evaporation temperature of the feedwater.
The feedwater is introduced into the evaporator section through an ofifice, and is distributed into every second plate channel (evaporation channels).
The hot water is distributed into the remaining channels, thus transferring its heat to the feedwater in the evaporation channels.
~av in i reached boiling temperature - which is lower than at atmospheric pressure - the feed water undergoes a partial evaporation, and the mixture of generated vapour and brine enters the separator vessel, where the brine is separated from the vapour and extracted by the combined brinelair ejector.
Having passed a demister the vapour enters every second plate channel in the condenser section.
The sea water supplied by the combined cooling/ejector water pump distributes itself into the remaining channels, thus absorbing the heat being transferred from the condensing vapour.
The produced freshwater is extracted by the freshwater pump and led to the freshwater tank.
1 .I FRESHWATER QUALITY
To continuously check the quality of the produced freshwater, a salinometer is provided together with an electrode unit fitted on the freshwater pump delivery side.
If the salinity of the produced freshwater exceeds the chosen maximum value, the dump valve and alarm are activated to automatically dump the produced freshwater to the bilge.
Instruction Manual for Freshwater Generator
Type J WP-26- C8OA 00
If there are no special requirements from the authorities, the produced freshwater can be used directly as drinking water.
MAIN COMPONENTS
The freshwater generator consists of the following components
1. Evaporator section
The evaporator section consists of a plate heat exchanger and is enclosed in the separator vessel.
2. Separator vessel
The separator separates the brine from the vapour
3. Condenser section
Just like the evaporator section the condenser section consists of a plate heat exchanger enclosed in the separator vessel.
4. Combined brinelair ejector
The ejector extracts brine and incondensable gases from the separator vessel.
5. Ejector pump
Normally, the ejector pump is delivered by Alfa Laval, and the ejector pump is a single-stage centrifugal pump.
This pump supplies the condenser with sea water and the brinelair ejector with jet water as well as feed water for evaporation.
Freshwater pump
The freshwater pump is a single-stage centrifugal pump.
The freshwater pump extracts the produced freshwater from the condenser, and pumps the water to the freshwater tank.

Clean the gasket groove with a clean cloth, dipped in a solvent (acetone, methyl ethyl ketone, trichlorethylene etc.).
Instruction Manual for Freshwater Generator
Type J WP-26-C80/100
Be careful when handling these solvents, as they may be hazardous to your health. Observe suppliers' instructions.
Gaskets, that have only loosened slightly, can be glued on. Clean gasket groove carefully with a sharp tool. Then clean the loose part of the gasket with emery cloth or sandpaper. Then clean groove and gasket with a solvent, and glue.
1.5.3 Preparation of new gaskets
Dry new gaskets with a clean cloth that has been slightly moistened with a solv- ent.
1.5.4 Fitting new gaskets
1. Apply a thin layer of glue to both gasket and groove.
2. Let the glue dry for 10-1 5 minutes.
3. Fit new gasket into groove.
Gaskets may sometimes be slightly short or long.
Short gaskets should be stretched before being fitted into the groove.
Long gaskets should be fitted into the grooves at the plate ends first and then gradually be pushed into the towards the middle.
If necessary, tape gasket into groove.

Chemical dosing of scale control chemicals
1.0 PREVENTION OF SCALING
During the evaporation of sea water there is always a risk of scaling on the heating surfaces. This will lead to a reduction of the K-values of the heating surface and decreasing freshwater production and reduction of plant efficiency.
In order to effectively prevent scaling the operators must be aware of the factors influencing the scale formation:
1.1 FEED WATER RATIO
The feedwater ratio is an extremely important factor. It is defined by the relationship between the feedwater amount fed into the plant and the produced amount of freshwater.
If the feedwater ratio is reduced, the concentration will rise in the plant subsequently resulting in scale formations.
Two things may shift the feedwater ratio: first of all direct adjustment of the feedwater system, and secondly exceeding the maximum freshwater production laid out for the plant. The operators must observe the following rules at all times.
DO NOT adjust feedwater system.
Instruction Manual for Fresh water Generator
Type J WP-26-C80/100
1.2 CHEMICALDOSAGE
In order to control scale formations on the heating surfaces and continuously ensure long operation periods without acid cleaning the plant, it is absolutely necessary to dose scale control additives to the feedwater. The operators must follow the instructions for chemical dosing given by the chemical supplier carefully.
If the distiller is operated at boiling temperatures above 45°C without chemicals, frequent cleaning of the evaporator will be necessary.
We recommend that you do not operate the freshwater distiller without recommended chemical dosage at boiling temperatures above 45°C.
1.2.1 Scale inhibitor dosage equipment for feed water
Please refer to drawing, see "FWG Order Specification"
When adding chemicals mix thoroughly to ensure a homogenous blend of chemicals and water.
Use a fully soluble scale inhibitor, e.g. on polymere basis. The following products can be recommended:
NALFLEET Evaporator treatment 9-91 3
AMEROYAL EVAPORATOR TREATMENT
HEXAMETHAPHOSPHATE
1. Mix the required quantity for 24 hours operation in the tank according to maker's instructions.
Instruction Manual for Fresh water Generator
Type J WP-26-C80/100
Adjust flowmeter to cover the maximum freshwater output from the distiller.
Flush the dosage system regularly.
1.2.2 Safety precautions with the use of chemicals
1. USE eye protection and gloves. Avoid direct skin contact, eye contact or contact with clothes.
2. CLEAN empty containers before disposal.
3. If chemicals are spilled on clothes, rinse with water and dispose off clothes.
4. If chemicals are spilled on the floor, rinse with water and suck remaining chemicals off with sand. Clean the spot immediately afterwards.
5. Scale inhibito~ is hazardous, if consumed in a concentrated solution. If consumed by mistake: IMMEDIATELY SEEK MEDICAL ATTENTION.
6. If eyes get in contact with the chemicals, rinse for at least 20 minutes. IMMEDIATELY SEEK MEDICAL ATTENTION.

Application
Conversion of seawater into fresh water by va- cuum distillation. For drinking, process water, and domestic use on ships and rigs, and in small power stations. Max. salinity 2 ppm.
Capacity
The JW(S)P-26-C80(B)/C100 covers a capacity range from 4 to 33 m3/24h, depending on the heating medium and seawater temperature. The capacities shown below are at a seawater tem- perature of 32OC.
Heating medium 'C
Working principle
The seawater to be distilled evaporates at a tem- perature of about 40°C as it passes between the hot plates in the evaporator. This evaporating temperature corresponds to a vacuum of approximately 93OA which is main- tained by the brinelair ejector. The vapours generated pass through a demister where any drops of seawater entrained are removed and fall to the bottom of the distiller chamber. The vapours continue to the condenser where they condense to fresh water as they pass between the cold plates.
Basic Equipment
Titanium plate heat exchanger in evaporator and condenser. Red brass separator and stainless steel demis-
ter, front cover and pressure plates. Seawater pipes in CuNi. The freshwater generator is equipped for jacket water heating and with a combined condenser cooling and ejector water system. Furthermore the freshwater generator is equipped with dump valve, water clock, automatic feed water regulator, com- bined brinelair ejector, instruments, freshwater pump with electric motor, internal piping and bed frame.
