WATER ANALYSIS: BOILER WATER TREATMENT, ENGINE
COOLING WATER, & PORTABLE WATER TEST

BOILER FEED WATER
-Boiler Feed Water is an essential part of boilers operations.
-The feed water is put into the steam drum from a feed pump. .
-The feed water is
never open to the atmosphere. .
-This cycle is known as a closed system or Rakine Cycle. .
-Proper treatment of boiler feed wataer is an important of operatig and
maintaining a boiler system .
-At a minimum, boiler feedwater must be softened water for low pressure
boilers and demineralized water for high pressure boilers. It must be free of
oxygen and essentially free of hardness constituents and suspended solids.
Two Different Boiler Water Treatment
External Treatment is the Internal Treatment is the

reduction or removal of impurities conditioning of impurities within
from water outside the boiler. In the boiler system. The reactions
general, external treatment is occur either in the feed lines or in
used when the amount of one or the boiler proper. Internal
more of the feed water impurities treatment may be used alone or in
is too high to be tolerated by the conjunction with external
boiler system in question. treatment
BOILER WATER TEST
-is an integral part of the routine boiler tests in many industries like:
*Textile
*Rubber Pulp annd Paper
*Food Disterilleries
*Dyers and Paint
-A regular boiler water test assures higher efficiency and reduced

maitenance of boilers.
-It is quite essential to maintain correct water condition by careful

monitoring of boiler water to avoid scale formation, reduction in
efficiency, steam purity, an d corrosive water conditions.

Engine cooling Water Test And Treatment
The cooling water of the engine should be

only demineralized (distilled) water with
proper treatment, which is necessary for
keeping effective cooling and preventing
corrosion of the system.
Sea water or fresh water contaminated by

sea water even in small amount is not
allowed to be used as cooling water of the
engine due to high risk of severe corrosion
and deposits formation in the system.
Checking Cooling Water and the System
The property of the cooling water may be changed during service due to
contamination or evaporation. Therefore, the cooling water itself and the
system should be checked periodically during service, preferably once a
week. Some of the changes may indicate the cause as follows:
Chloride content increasing:

Check possibility of seawater penetrating into cooling water.
Check the system which includes sea water, for example fresh water cooler
cooled by sea water.
If the quality of the cooling water after checking exceeds control limit by
water treatment, the cooling water should be replaced completely by newly
treated water.

PORTABLE (DRIVING) WATER TEST
to monitor the quality of the drinking water on board
the vessel by providing tests for important operational
control parameters and verification tests for bacteria
that can be of risk to human health
potable water analysis helps clients monitor the water

quality on their ships, helping them maintain higher
quality levels and reducing the risk of infection or
illness.
The range of tests can be used on the ship either as a

standalone control solution or as a supplement to
laboratory analysis, dependant on flag state guidelines.
Designed recreational water analysis, including
water used in swimming pools and hot tubs. For
owners and operators of cruise ships,
recreational water testing provides additional
peace of mind, helping ensure reasonable care
