Toxicological effect of water pipelines on water quality

Superlit GRP pipes are completely resistant in ozoned-water environments

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

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.” Superlit – Turkey
