In the power generation industry, water quality is specified by boiler and turbine manufacturers. The removal of dissolved ions and dissolved gasses, such as oxygen and carbon dioxide, must be reduced to extremely low concentrations long before the water enters boilers for steam production.
Dissolved gas control in a nuclear power plant’s water system, including the primary make-up water storage tank and refueling water storage tank, can be essential to reduce radiation source term (defined as a release of radioactive material). In particular, controlling dissolved gases can also help reduce the formation of unwanted radionuclides, such as 14C and oxides of 60Co, and alleviate primary water stress corrosion cracking (PWSCC).
Now that the U.S. Environmental Protection Agency (EPA) has issued its rule for cooling water intakes under Section 316(b) of the Clean Water Act, the race is on for more than 600 power plants and manufacturing facilities to comply. Right now, there is probably no better example in the water industry of how carefully choosing among compliance options can lead to millions of dollars in cost savings.
Water is the lifeblood of electrical power plants, whether they are water-cooled steam plants or turbine-spinning hydroelectric installations. Regardless of how the facility generates electricity, there is a growing awareness that each power plant is part of its own, unique industrial watershed — drawing water from the environment, altering its contents and temperature, releasing some to the atmosphere as steam, and returning the rest to receiving waters.
Controlling dissolved oxygen (DO) levels during beverage production is vital for ensuring consistent product quality and shelf life. This is particularly true for canning, where high DO levels can cause breakdown of the can lining, corrosion and even leaking – which in turn can result in product waste and customer dissatisfaction. In some cases, can supplier warranties have exclusions for high DO levels.
IMEC (Interuniversity Micro- Electronics Center) in Belgium is Europe's largest independent research center. It focuses on microelectronics, nanotechnology, and enabling design methods and technologies for ICT (Integrated Circuit Technology) systems. IMEC's research runs 3 to 10 years ahead of industrial needs.
The client revived, expanded and modernized its operations in order to produce rare earth materials in high volumes and in an environmentally responsible manner. As part of the expansion, the client contracted Veolia to design and build a new water treatment plant for their state-of-the-art rare earth facility.
A wide range of industrial operations rely on cooling systems to function. And, in turn, these systems require cooling water to function. So, it stands to reason that a wide range of water treatment issues need to be considered and addressed so that cooling water system upsets are avoided and everything continues to run as it should. Oftentimes, an efficient industrial operation depends on efficient monitoring and treatment of cooling water.
Anyone remember the old cars of the 1950s and 1960s? They all pretty much came equipped with an ammeter, an oil pressure gauge, a water temperature gauge, as well as a speedometer and a fuel level gauge. Then came the ’70s, ’80s, even the ’90s and turn of the century cars, where “idiot lights” replaced the ammeter, oil pressure and water temperature gauges. Now the latest up-to-date vehicles have again returned to certain analog gauges, and digital read-outs, as well as computerized “information centers” that tell the operator more than they possibly ever wanted to know about their vehicle.
The Villoresi Channel, located north of Milan, was designed with the main purpose of agricultural irrigation while providing water to the city of Milan. The paths running along the canal were also used for recreational purposes and cross through some of the most beautiful natural parks in Lombardy.
