Calcium hypochlorite is white or light grey in colour - powder or
granules. It is widely used for water treatment and as a bleaching
agent (bleaching powder). This chemical is considered to be
relatively stable and has greater available chlorine than sodium
hypochlorite (liquid bleach) and yearly loss of chlorine is low.
It can whiten pulp, silk, cloth, fibre and starch. It is also used
in dealing with the polluted water, and as an effective disinfectant
public health, family sanitation, swimming pool, drinking water,
vegetables, fishpond. In addition, calcium hypochlorite may be used
to manufacture chloroform.
Normally there are following basic problems encountered in the
maintenance of swimming pools.
Growth of bacteria, viruses and other microbes on the surfaces of
the swimming pools and its water exposed to air which may cause
infection and diseases to the swimmers.
Due to use of water by swimmers harmful bacteria germs get
transmitted into water and become source of many water borne
Contamination of water from oils, perfumes, urination etc. imparted
into the water from the body & hairs of the swimmers makes water
unfit for further usage over a few cycles.
These are the reasons why swimming pools require regular and
effective treatment by disinfectants. Chlorine is a time tested and
trusted sanitizer. It destroys microorganisms and protects swimmers
It is a dry form of Chlorine and is very safe to handle. It
is readily soluble in water and is free from any organic substances.
Its pH of 10.8 helps to maintain optimum pool water pH of 7.2 to
7.6. When using Chlorine gas or Tri chloroisocynurate (TCCA)
products for swimming pool sanitization, the pH drops and leads to
corrosion of pool surfaces. Due to these reasons we provides better
protection for concrete, plaster, pipes and other pool equipment.
It acts as a bactericide, germicide and algaecide and can be
used for disinfecting and cleaning purposes.
It is a strong oxidizer and can easily destroy organic body
oils and other organic debris if any present in the swimming pool
It contains easily soluble granules.
Due to very less exposure of residential pools to the
sunlight loss of chlorine is negligible. Hence, there is no
requirement of stabilizers such as Isocyanuric acid which further
contaminate the water.
It provides crystal clear and clean pool water.
It works to maintain properly established alkalinity levels
without further chemical addition.
Most Suitable, Sanitizer and Versatile for Super Chlorination
(Shocking) of Commercial Pool Water :
It is very good for shocking to destroy chloramines.
Chlorine is unstabilized and hence there is rapid growth of
residual chlorine level into water, which is needed for super
The excess chlorine is reduced faster to make swimming pool
available to swimmers in a much shorter period of time compared to
one superchlorinated with Trichloro containing Isocyanurates.
For routine sanitization also it is used in all commercial
pools with added safety by adding stabilizer separately to minimize
the loss of chlorine due to exposure to sunlight almost by 50%.
It’s higher alkalinity works as a buffer and helps to keep
the pH stable when any acidic material is introduced into water. It
is also an important factor in preventing water from turning cloudy
and keep the pool water clean and clear.
Calcium hardness protects the pool equipment and it contains
