Accurately Measuring Network Leakage
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives
Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.
Phosphate Corrosion Control In Drinking Water
Corrosion occurs because metals tend to oxidize when they come in contact with oxygenated water, resulting in the formation of stable metal oxides.
Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction
Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day.

(E)-2-Nonenal In Beer
Numerous compounds contribute to changes in beer flavor as it becomes stale. One of these compounds, (E)-2-nonenal, has been investigated as a major source of the papery/cardboard flavor that develops in aged beer.
Application Note: Water Flows From The Golden Hills Of California
Each morning John Johnson drives the few miles from his smalltown home in northern California to the Center at Pardee Reservoir. Nestled among the foothills of the Sierra Nevada mountain range, the reservoir is a long 100 miles away from San Francisco Bay. By YSI
Removal Of Chloramines With Activated Carbon
In order to reduce the formation of harmful disinfection byproducts in drinking water, alternative disinfectant use has become increasingly widespread. Monochloramine is a leading alternative disinfectant that offers advantages for municipal water. This tech brief details the removal of monochloramine using activated carbon.
Degassing Boiler Feed Water in China with 3M™ Liqui-Cel™ Membrane Contactors
ShenLan Environment Inc. located in Shanghai, China uses 3M™ Liqui-Cel™ Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.
Network Monitors Water Quality In Shale Gas Drilling Region
High-pressure injection of water, sand, and chemicals that fracture shale deposits deep underground to free trapped natural gas is employed by drillers tapping the Marcellus shale beds, a geologic deposit that stretches from central New
York to Virginia and contains gas believed to be worth hundreds of billions of dollars. By YSI
Bringing Efficiency And New Confidence To BOD₅ Analysis
Biochemical Oxygen Demand (BOD) analysis is the test everyone loves to hate—and for compelling reasons.
