What classifies as water pollution and why is it an issue?

The UN declared 2005-2015 as the International Decade for Action ‘Water for Life’. Yet each day thousands of people still die as a result of contaminated water. This does not even take into account the millions of organisms that perish every year thank to polluted water sources. Water pollution is a huge issue that is made more so by the fact that unfortunately, water is ...

Bredel 65 pumps eliminates AODD pump issues at major lithium battery plant

Bredel 65 hose pumps from Watson-Marlow Fluid Technology Group are now providing constant efficiency in ball-milling processes at a high-volume battery plant in China. Previously, ball milling was being compromised by a poorly performing AODD (air-operated double diaphragm) pump used for high-viscosity slurry recirculation. Reduced flow/efficiency and leaks were proving disruptive ...

What Causes Water Main Leaks?

The number one cause of water leaks today and moving into the future will be the aging infrastructure. “A large part of the US public water system dates back to the years shortly after World War II, therefore, a significant amount of buried infrastructure is at or very near the end of its useful life.” – Qureshi & Shah, Journal AWWA. When aging infrastructure is combined ...

Locating Leaks for Cooling Water Systems

This article illustrates how to locate leaks on cooling water systems in loud, industrial environments like Nuclear or Coal power generating plants without digging or putting anything inside the pipeline. Infrared-Energy Pattern Analysis (IR-EPA) works on all pipeline sizes and all pipeline materials because it identifies the water outside the pipeline instead of listening for leak noises ...

Experimental investigation of leak hydraulics

In recent decades the hydraulics of leaks, i.e. the definition of the relationships linking the hydraulic quantities in pipes with leaks, has received increasing attention. On the one hand, the definition of the relationship between the leak outflow and the relevant parameters – e.g. the leak area and shape, the pressure inside the pipe and outside the leak, and the pipe material ...

Closing the last Energy Leak

The heat contained in wastewater is one of the last major untapped resources in the field of renewable energies, despite the fact that it may some day provide some 20% of the heating energy we need. This huge potential has been addressed by a Swiss engineering office, Rabtherm AG, which now supplies patented technology for generating energy from wastewater, used for heating or cooling buildings. ...

Monitoring and Alarming Water Leaks in a Library Basement

CAS DataLoggers recently provided the monitoring and alarming solution for a library housing a number of rare books and documents in their basement record storage area. The library’s director needed a wireless device to detect when water entered the basement during the seasonal rains, and also needed alarming capabilities to give her instant email ...

Evaluating the pressure-leakage behaviour of leaks in water pipes

Much progress has been made over the last decade in understanding the behaviour of flow through leak openings with changes in water mains pressure. In particular it has been established that variations in leak areas with pressure is the main factor responsible for the range of leakage exponents observed in practice, and several numerical and experimental studies have investigated this ...

Detect Leaks and Analyze Water Consumption with WaterSignal

Did you know it will cost an estimated $1 trillion over the next 25 years to upgrade the nation’s water system to run more efficiently? While part of the problem is fragile, hundred-year-old water mains, it also falls on property owners to ensure they are doing their part to save water — for both the environment and their wallets. But how? ...

Tackling Non-Revenue Water by Identifying Small Leaks

Small leaks sink big ships – the same can be said for large-diameter pipes in utility networks. While large leaks or ruptures are seen as newsworthy stories accompanied by images of water flowing down the streets; smaller leaks can often be more devastating. Left undetected, they can add up over time, contributing significantly to ...

Petrox Bioremediation of Oil Pipeline Leak

Petrox bioremediation was used to treat unrefined oil that leaked from a pipeline in Texas. The oil migrated from the impacted soil into ground water and seeped into the surface water in a nearby river. After one application of Petrox, the oil concentrations in ground water at the source decreased from 600ppm to less than 100 ppm. Two more treatments reduced the ...

Leak behaviour in pressurized PVC pipes

The correct definition of the leak law, i.e. the relationship between the leak outflow, the total head at the leak and other relevant parameters such as the pipe material, can seriously affect the accuracy of the numerical models used for the management of water distribution systems, either if they are used to forecast the leakage reduction by pressure management or to locate and size the leaks ...
