Connecticut utilities repelled numerous cyberattacks over the last year, according to a new report from the state government.
While accurate flow measurement is critical for most industries, flow conditions that change over time can make it difficult to properly size a flow meter. Replacing a meter as the flow changes is impractical and expensive. In addition, flow disturbers can greatly impact meter accuracy, so addressing that issue is important as well. A uniquely designed flow meter may be the solution to both problems.
In an effort to lower operational costs and extend the life of the dewatering centrifuge, operators in Springboro, OH, began to look at the polymer activation equipment in use at the plant. The Polyblend® M-Series emulsion polymer activation systems had been in steady operation for over 10 years. The equipment still performed reliably, but operators were interested in ways to achieve greater efficiency. They were aware of the new Polyblend® Magnum mix chamber, with its enhanced two-zone mixing energy.

Flow meter accuracy is critical for process control but can be hampered by upstream and downstream flow disturbers. This problem may be addressed during the design process, though in some circumstances it’s impossible to eliminate disturbers.
Most of us don’t have to think about the vital infrastructure that supports our society. Water is delivered to our homes and businesses 24/7, and wastewater is efficiently and cleanly whisked away. The ability of our utilities to manage these services means we only take notice at times of inconvenience: water outages, sewer blockages, or stormwater overflows.
Central district heating systems have gained attention in recent years because they can be more efficient than localized boiler units. The efficiency of district heating is usually due to power generation plants being able to produce heat and electricity simultaneously. District heating also helps prevent pollution by using advanced flue gas cleaning techniques.
A major power plant in Thailand is using 3M™ Liqui-Cel™ Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel membrane contactors are being used to lower the CO2 inlet into an Ionpure Electrodeionization (EDI) system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. Manufactures of the EDI equipment suggest lowering the inlet CO2 to reduce the load on the equipment and improve the water quality.
For any drinking water or wastewater treatment operation, pH neutralization is never far from top-of-mind.

Water utilities in the U.S. were once operated almost completely by private companies. That began to change when Boston, New York, Los Angeles, and other large cities expanded in the late 19th century. Water utilities failed to manage the increased demand and government leaders stepped up to assume responsibility for adequate water resources. That’s been the case for decades, but now water problems are critical again.
