MANAGING WORLD WATER SUPPLIES WITH PREDICTIVE MAINTENANCE TECHNIQUES
W 44
ith the world’s population projected to increase
exponentially over the next few years, the need to
conserve and successfully prevent the pollution of the Earth’s water supplies has never been more urgent.
Although current practices including metering technologies, construction of new storage infrastructures and public awareness campaigns are helping to address the issue of future water supply concerns, a great deal of work remains to be done. Particular challenges include but are not limited to the need to minimise wastage during the potable treatment and distribution stages, ensuring that water is correctly treated and that, once this treated water enters the distribution pipe network, every drop is accounted for. Increasingly stringent legislation also demands that wastewater is returned to an acceptable standard before it is released back into to the environment, with stiff financial penalties facing any who fail to comply.
At the forefront of the battle to ensure water quality is a new generation of measurement
Water treatment processes require complex and extensive measurement of multiple parameters to ensure quality, safety, and environmental sustainability. Jonathan Penn, product line manager for ABB Measurement & Analytics, looks at how new instruments and analysers are enabling new predictive maintenance techniques that can help keep treatment processes running at top efficiency.
instruments and analysers that not only provide high quality water assessment throughout potable and wastewater treatment processes, but also measures the efficiency of the water treatment plant itself. Given the huge quantities of water that flow through treatment plants each day, it is crucial that problems are identified as quickly as possible. This is where predictive maintenance can make a profound difference.
PREDICTIVE MAINTENANCE DEFINED Industry in increasingly awash with new technologies and techniques that are accelerating the global move to Industry 4.0 and, with it, the Internet of Things (IoT). IoT in particular is delivering huge volumes of data that can be used to create and analyse models
for a vast range of tasks, including the ability to monitor instrument status and performance for even the slightest deviation from the norm. As such, these technologies have become a central component of predictive maintenance programs by making it possible for operators to proactively intervene to intercept and resolve potential problems before they take root or get out of hand.
Rapid developments in new digital water sensing technologies now offer unparalleled real-time insights to water quality using high accuracy data that experiences none of the shortcomings of conventional sensor types. Operators using these new devices are assured of the far more accurate measurement of the majority of potable and wastewater treatment quality parameters.
