Case Study: Municipal Water Works Various Municipalities in Different Countries
Many Municipal Water Works and maintenance department engineers have been dealing with corrosion and scale which cause pipes to burst or leak (known as Physical Non-Revenue Water, or PNRW) lost is expressed as % of the volume per km of piping network per day.
WATER SYSTEM CHALLENGES
Typically, water is fed to every house or building or around the city (or municipality) through a network of pipes that are sometimes 30 to 40 years old (or even older, in some places). These pipes are corroded with significant rust and calcification internally, resulting in obstructed water flow throughout the pipe network. Under these conditions, expensive repairs or even replacement became necessary on a regular basis. There are many piping breakdowns, leaks and outbursts every year across the world, and PNRW levels are known to be 1.5% to 9% (!) in some places around the world.
SOLUTION
Reducing the PNRW is a complex process, and ScaleBuster® has been found to be one of the innovative solutions. As the ScaleBuster® reduces scale buildup and protects the piping system against corrosion, it contributes to longer life span of the municipal piping network.
RESULTS
Water Works Maintenance Director who was interviewed 12 months following the first installations indicated that after only a few months of operation with the ScaleBuster®, the pipe system downstream was clearly less corroded compared with other sections in the vicinity. There was significantly less calcification inside the pipes in less than a year, improving water flow throughout the sub-development. They have adopted the solution and work on installing new ScaleBuster® units for new as well as old pipes, as preventative maintenance program on the piping network.
ABOUT THE TECHNOLOGY
The patented ScaleBuster® technology completely replaces traditional chemical treatment; providing control of scale and corrosion in various water process systems to create an exceptionally clean system. This dramatically reduces energy and water consumption, while reducing or, in certain cases, eliminating toxic water discharge to the environment.
