Toxicological effect of water pipelines on water quality

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 expensivemaintenance, 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

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

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 toxi- cology of chlorination, water ozonization is becomingwidespread all over theworld 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.”

The pipe structure is formed from polyester resin Vacuum pipe lifting Schoenbeck GmbH & Co KG has introduced additional models in its vacuum pipe lifting range, incuding the ELiTE 12 & 16TE (tonnage/electrical) vacuum pipe lifter models and the ELiTE LiTE power pack concept. The ELiTE 12TE vacuum pipe lifter is electrically powered by the user’s main power supply (380V/420V, 50 or 60Hz). Supplied with either a SWL of 12,000 or 16,000kg (26,500lb/35,200lb) units, both can be delivered with a central single or two outer double hook eyes for tower/gantry crane applications. The power is transported to an electrical motor, which in turn drives a vacuum pump. In the event of a factory power failure/power tripping, the machine has sufficient warning power to operate for an additional 8-12 hours. A power pack is loaded prior or during normal lifting operations, and is activated automatically on demand. Standard warning sirens/flash lights are incorporated, as are safety valves and -40°C solenoids for extreme cold working environments and pre start-of-work system checks. Schoenbeck also now manufactures C hooks for steel coils with SWLs of 10,000kg to 40,000kg (22,000lb to 88,000lb). The standard model is delivered with a crane eye (size according to requirement), while alternative models can be equipped with a power swivel/rotor.
