Water treatment is essential before water is discharged to be
used in industries, businesses, and homes in Australia. Using chemicals to
treat water helps to remove harmful bacteria and substances. After treating the
water using chemicals, it can be recycled into the water source. Different
chemicals can be used to treat water such as lime, chlorine, and hydrogen
peroxide.
Chlorine
Chlorination is the most common disinfectant for swimming pools
and public drinking water. Chlorine helps to prevent the spread of diseases
such as E-coli. Chlorine also destroys algae, bacteria and mould that may grow
on the walls of water tanks. Chlorine can also remove unpleasant odours and
tastes from drinking water.
However, it can be difficult to handle chlorination without
experience and expertise. The chlorination used for laundering, showering and
swimming can dry out the hair and skin and may cause skin and eye irritation.
Using chlorine for water treatment in Australia can make the water to fade
fabrics.
Lime
There are high levels of dissolved minerals in hard water. These
minerals can build up in internal systems and pipes to cause permanent damage.
Water softeners made with lime can treat water and improve the levels of
arsenic in water. Lime can also be used to alter the pH of the water and
provide an unconducive environment for viruses and bacteria. In some cases, the
water pH levels can be too high when lime is used to soften it. When you add
lime to chlorinated water, hypochlorite formation is an inferior disinfectant
to free chlorine residuals.
Hydrogen peroxide
This is a bleaching agent that can be used for water treatment in
Australia to lighten hair, whiten teeth, and bleach textiles and fabrics. It can
also be used to disinfect water by inhibiting the growth of bacteria and
removing pollutants. Hydrogen peroxide is safe and it doesn’t produce gas or
residue.
