MAJOR causes of water pollution include
industrial waste disposal, organic disposals
such as artificial manure and sewerage,
agricultural pesticides and the chemical
structure of the source.
Various disinfection methods have been
in use for a number of years. However,
advanced academic research has identified
that some disinfection methods that were
believed to be harmless have been proved
to cause toxicology for human health.
The most common technique for
disinfection of water has been chlorination.
The reaction of chlorine with organic
substances in the water, as well as the
reaction with the pipe walls it flows through,
have been shown to display a high possibility
of carcinogenic toxicology. For instance, the
outcome of vinyl chloride in PVC pipes, or
the outcome of ethylene chloride in PE pipes,
have been proven to create a carcinogenic
effect. Therefore, in the USA and many EU
countries, ozone rather than chlorine is used
as the disinfection agent for water.
For the healthy disinfection of water
Toxicological effect of water
pipelines on water quality
with ozone, most pipes need an expensive
special lining layer to prevent penetration
of ozone inside the pipe walls. However,
composite pipes such as glass fibre
reinforced polyester (GRP) pipes, have an
advantage over other types of pipes for an
ozoned-water environment.
Superlit GRP pipes do not need a
special lining layer to prevent chemical
reaction of disinfection chemicals with the
pipe walls. With re-engineering of polyester
resin, which forms the pipe structure, GRP
pipes become completely resistant for the
ozoned-water environment. Since pipe wall
deformation does not take place, Superlit
GRP pipes do not require complicated and
expensive maintenance, even in the long-
term. Superlit claims that since both internal
and external surfaces of its GRP pipes are
highly resistant to aggressive chemicals
and structural corrosion, pipe performance
displays excellent results, even under high
pH conditions.
Superlit production director PhD Eng
Alpay Gulcan emphasised the importance
of the issue: “In a world where clean water
scarcity as well as the polluting sources are
both increasing very fast, the effect of water
transmission line on water purity can not be
disregarded. Likewise, to avoid carcinogenic
toxicology of chlorination, water ozonization
is becoming widespread all over the world
for a healthy purification. When these two
approaches are taken into account, the
most feasible water transmission solution,
where water purification is kept stable with
high corrosion resistance for ozoned-water
transmission, is highlighted as Superlit GRP
pipe systems.”
