Learn about the common cooling towers problems
and how to prevent them

In every industry, there are heating and
ventilation systems that use cooling towers to
remove heat from an industrial process or for
cooling large buildings. However, some common
issues can occur in cooling towers regularly.
Therefore, its important to know what to look
out for in advance, which can help you save time
and resources down the line. The laws and
regulations to improve water efficiency and the
need to reduce costs means that cooling towers
need to be running as efficiently as possible. In
order to keep your cooling system at optimum
performance, there are a few things that should
look out for. This will help you understand
common cooling tower problems solutions so you
can optimize your cooling tower water treatment
for more efficiency.

Problem High amount of blowdown
Cooling towers remove excess heat by evaporation,
and in turn use lots of water to make up the
difference. Due to the makeup water being added
into the cooling tower, solid deposits can remain
in the cooling tower. This increases the need for
a blowdown which removes solid waste and
dissolved solids buildup to prevent scaling or
corrosion in the equipment.
Solutions ? Water filtration ? Side-stream
filtration ? Increased cycle of concentration
? Maintain quality of makeup water by removing
scale forming and corrosion causing impurities.

Problem Low Cycle of Concentration
In cooling towers, CoC helps measure how much
concentrated buildup is in the cooling tower
water compared to the ratio of makeup water. The
higher cycle of concentration means the lesser
need for makeup water and blowdown, thus saving
water and cost. The ideal ratio is at least three
to six cycles of concentration which is 3 to 6
times the concentration of deposits in the water
cycle than the makeup water.
Solutions ? Better cooling tower control by a
water treatment system ? Minimizing blowdown
monitoring conductivity ? pH/alkalinity control
to minimize scale formation ? Decreasing feed
hardness, iron, and silica

Conclusion
Every good business stands on an efficient
operation that includes keeping the overhead
down. Being aware of any potential problems in
cooling towers and knowing how to solve them is
essential to the success and efficiency of your
process. To ensure that the cooling towers work
without any error, they have to be maintained
regularly and operated with care. Even with the
cooling tower water treatment, you need to take
care of it in a proper manner. This will not only
increase the lifespan of the equipment, but it
will reduce expenses and also prevent any serious
issues in your cooling system.
