System Description
1.0.0 Working Principle

The combined brine/air 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 spring loaded
valve (full open by 2 bar) orifice, 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.
Having 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 brine/air ejector.
Having passed a demister the vapour enters every second plate channel in the top
of the condenser section.
The sea cooling water supplied to the condenser by the combined cooling/ejector
water pump distributes itself into the remaining condenser channels, thus absorbing
the heat being transferred from the condensing vapour.
From outlet side the condenser, the sea cooling water is used as jet water for the
ejector and as feed water for evaporation.
The produced freshwater is extracted by the freshwater pump and led to the fresh-
water tank.
1.1.0 Freshwater Quality

To continuously check the actual salinity 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.
If there are no special requirements from the authorities, the produced freshwater
can be used directly as drinking water.

System Description
1.2.0 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 brine/air 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
cooling water and the brine/air ejector with jet water as well as feed water for
evaporation.
6. 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.
7. Salinometer
The salinometer continuously checks the salinity of the produced water. The
alarm set point is adjustable.
8. Control panel
Normally, the control panel is delivered by Alfa Laval. It contains motor starters,
running lights, salinometer, contacts for remote alarm and is prepared for start/
stop.

Maintenance
2.0.0 Why you need to perform regular maintenance duties

Regular maintenance of the plant will improve performance and availability.
The maintenance schedule on the following pages will tell you how often service
should be performed on the main components.
As the actual operating conditions of the plant are of major influence on the life time,
the overhaul dates are not obligatory but only recommended intervals.
When the plant has been in operation for a longer period of time and experience has
been established as to the actual performance, it will be possible to adapt the main-
tenance schedule.
For service on minor components please refer to component instructions.

2.2.0 Maintenance of Separator Vessel

The front cover and the pressure plates for the heat exchanger sections (evaporator
and condenser) are made of stainless steel with a special chemical treatment. This
treatment will reestablish normal surface oxidation after work- up at the factory. The
preparation is a natural protection of the stainless steel.
CAUTION
To preserve this natural protection DO NOT scrape or scratch the inside

surface of the front cover.
Whenever the separator vessel is opened,
• check that the anodes are functioning.
If the anodes are not functioning and/or scarified, replace them.
NOTE
If the unit is stopped for a longer period than 14 days.
• Open front covers and clean unit inside with freshwater.
• Let the unit dry out completely, before closing covers.

Pull the old gaskets out of groove.
If the gasket cannot come off directly, heat the back of the gasket groove with a
hot-air blower or butane gas burner.
Pay attention not to overheat the plates.
You will obtain a suitable temperature, if the flame is held 10 to 15 cm behind the
plate.
WARNING
DO NOT use acetylene gas.
2.5.2 Cleaning
Charred or loose glue and rubber remains must be removed, e.g. using a rotating
stainless steel brush. The width should be adapted (Ø40-50 mm, width 8-10 mm).
Thin layers of glue which are difficult to remove, may remain.
Clean the gasket groove with a clean cloth, dipped in a solvent (acetone, methyl eth-
yl ketone, trichlorethylene etc.).
14 Majwpe00.fm
Maintenance
WARNING
Be careful when handling these solvents, as they may be hazardous to

your health.
Observe suppliers’ instructions.
Gaskets, that have loosened, 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.
Finally clean groove and gasket with a solvent, and glue.
2.5.3 Preparation of New Gaskets

Dry new gaskets with a clean cloth that has been slightly moistened with a solvent.
2.5.4 Fitting New Gaskets

1. Apply a thin layer of glue to both gasket and groove.
2. Let the glue dry for 10-15 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.

3.0.0 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 de-
creasing freshwater production and reduction of plant efficiency.
In order to effectively prevent scaling the operators must be aware of the factors in-
fluencing the scale formation.
3.1.0 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 fresh-
water.
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.
CAUTION
DO NOT adjust feedwater system. Feedwater pressure min. 3.0 max. 4.0
bar g.
3.2.0 Chemical Dosage

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 instruc-
tions for chemical dosing given by the chemical supplier carefully.
Cdgnpe00.fm 17
CAUTION
If the distiller is operated at boiling temperatures above 45°C without chem-

icals, frequent cleaning of the evaporator will be necessary.
We recommend that you do not operate the freshwater distiller without rec-
ommended chemical dosage at boiling temperatures above 45°C. Even at
lower temperatures it can be recommended.
3.2.1 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 polymer basis. The following products can
be recommended:
NALFLEET Evaporator treatment 9-913
AMEROYAL EVAPORATOR TREATMENT
HEXAMETHAPHOSPHATE
1. Mix the required quantity for 24 hours operation in the tank according to mak-
er’s instructions.
2. Adjust flowmeter to cover the maximum freshwater output from the distiller.
3. Flush the dosage system regularly.
18 Cdgnpe00.fm
3.2.2 Safety Precautions with the use of Chemicals
WARNING
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 remain-
ing chemicals off with sand. Clean the spot immediately afterwards.
5 Scale inhibitor 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.

9.2 Production Information 9.2.2 Freshwater Generator
JW(S)P-26-C80(B)/C100
Edition 99-01
9.2.2.1 General description, JW(S)P-26-C80(B)/C100
Application
Conversion of seawater into fresh water by vacuum 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 35 m³/24h, depending on the heating medium and
seawater temperature. The capacities shown below are at a seawater temperature of 32°C.
Working principle
The seawater to be distilled evaporates at a temperature of about 40°C as it passes between the hot plates in the
evaporator.
This evaporating temperature corresponds to a vacuum of approximately 93% which is maintained by the brine/
air 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 demister, 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 wa-
ter regulator, combined brine/air ejector, instruments, freshwater pump with electric motor, internal piping and bed
frame.
