Water and wastewater leaders are unsung heroes. Clean, safe water is essential to human life and to the well-being of the environment, yet it is grossly underfunded. Limited resources lead to deferred maintenance and difficult decisions.
In the Pilbara region of Western Australia, 1,200 kilometers northeast of Perth, Roy Hill Iron Ore (Roy Hill) is developing an open pit, bulk mining facility capable of processing 55 megatons of iron ore annually. Set to be the country’s largest iron ore mining operation, the AUD 10 billion project includes a water supply and dewatering network spanning 300 square kilometers that needs continuous adapting to meet the changing mining and ore processing requirements over the 20-year life of the mine (LOM).
Privatization of the United Kingdom’s (UK) water industry 25 years ago required providers to implement asset management programs (AMP) whereby water boards tendered contracts to construction firms to update the industry’s antiquated assets and help keep infrastructure properly maintained.
China’s 12th Five-Year Plan (FYP) (2011-2015) allotted 20 percent more funds for municipal wastewater treatment projects to address the pervasive pollution caused by rapid urbanization and inadequate sewage disposal.
For a pH sensor to maintain an accurate reading, the sensor must remain clean. Specifically, the glass measuring electrode cannot become coated, and the reference electrode assembly must not become coated, plugged or otherwise contaminated by the process solution. Here’s how to clean pH sensors to ensure correct operation.
As a bulk emergency chlorine vapor scrubber system approached the end of its anticipated 20-year useful life, the city engaged Integrity Municipal Systems, LLC (IMS) inspected the equipment and proposed a system refurbishment plan that would ensure proper system performance and safe storage of the 30,000 gallons of corrosive caustic soda contained within it.
The Utility Distribution team at the University of Illinois at Urbana-Champaign manage the water system which serves the entire campus. The University purchases water from Illinois American Water which is distributed across the campus for uses as diverse as chemistry labs, agricultural research, and competitive swimming complexes.
In recent years, the debate about which technology is best suited for level monitoring and open channel monitoring (OCM) applications has taken some traction. There are those who argue that ultrasonic level technology has been uncontested as the standard for level and OCM applications in the water industry. The counter-argument is that radar technology is more effective because it is more robust and accurate than ultrasonic technology.
Users often question whether their measuring devices are working properly and within specified measurement accuracy. The new CoriolisMaster flowmeter models by ABB include technology for integrated online diagnosis and accuracy verification. This technology constantly monitors the oscillating meter tube within the flowmeter for erosion and coating deposits.
Achieving consistent water pressure is a challenge for geographical areas that have grown faster than the development of infrastructures to accommodate water demand and for businesses such as fast food restaurants and strip malls.
