Numerical simulation of coolant mixing in a pressurised water reactor with different CFD methods based on complex meshes
This paper describes the numerical simulation of coolant mixing in the downcomer and the lower plenum of the Rossendorf test facility, ROCOM. ROCOM is a 1:5 scale Plexiglas model of a German pressurised water reactor, allowing conductivity measurements by wire mesh sensors and velocity measurements by the LDA technique. The CFD calculations were carried out with the CFD codes CFX-4 and CFX-5. In ...

Scientists submit suggestions for improved European water quality
Although the European Water Framework Directive has been in place since 2000, some say revisions are needed to help the continent achieve even better water quality. Scientists from across Europe have carefully looked at the document to determine what is needed to help make the framework more effective. The directive, which addresses water pollution, says all bodies of water in Europe — ...

USP <645> - simple automated analysis of ultrapure water
H2O – two simple elements, oxygen (O) and hydrogen (H), fuse together to form one of the most important molecules in the world: water. Water is everywhere on Earth and it is vital for our health and survival. It often contains other ions like calcium, magnesium, and chloride which are essential for the human body to function. However, in specific situations, ...

Conductivity Measurement in high purity water samples below 10 microsiems/cm
High Purity Water Resistivity/ Conductivity Measurement Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H* and OH" ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 HSiemens'cm or a resistivity of 18.18 mQ-cm at 25 °C. In order to know the conductivity or resistivity of ultra-pure water it is ...

TDS: `The Done Sale`
Many Americans have at least some concern that their tap water is problematic, yet they don’t know where to begin. The TDS, or total dissolved solids, meter can be the first step in determining if there’s a problem. The term TDS has long been well-known in the water treatment industry, yet still has not penetrated the mass consumer market. However, by hearing your brief explanation, ...

Common water quality sensors
The role of water quality sensor:Water quality sensor is a device used to measure water quality, usually consisting of multiple sensors and measuring systems. The function of water quality sensor is to detect various substances in water, and convert them into electrical signals, and then through the measurement system for processing and analysis, get the indicators of water quality. Water quality ...

TDS and EC meters for hydroponics explained
As technology advances, questions inevitably follow. Due to the rapid growth of the hydroponics and indoor gardening industry, it is important for growers to be familiar with the technology, in this case instrumentation. There is a myriad of nutrients and fertilizers available to help you cultivate the best possible plant yields, but what is consistent among all of them is they need to be ...

ITS marketing manager quoted in WaterTech
Professional, ethical testing will start you off on the right foot and will directly determine which services the customer may need. Many substances could be in a customer’s water, but, “It’s not necessary to test for every parameter; that’s what labs are for,” advises Rob Samborn, director of sales and marketing for HM Digital, a Los Angeles-based maker of water ...

Conductivity: A Fundamental Water Quality Parameter
Monitoring the conductivity of groundwater and surface water is an essential task for maintaining the quality and safety of our water resources. Continuous monitoring of conductivity can help identify long-term trends and seasonal variations in water quality, which are used to predict changes in water availability and quality over time. This can aid in the development of effective ...

Time lapse resistivity/IP survey case study
Changes in underground electric resistivity is typically resulted by the variations in groundwater conduction and soil water content. Monitoring this variation will help operator gain a better understanding of the underground water distribution over time. This may facilitates operators monitor abnormal underground or structural behaviour. Time lapse resistivity survey is therefore very useful ...

Analysis of PFCs in Environmental Water Using Triple Quadrupole LC/MS/MS
Organofluorine compounds such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) are highly stable chemical compounds which are widely used as water repellents, oil repellents and coating agents. These compounds do not decompose easily in the natural world due to their stability. Reports of their detection in rivers, streams, tap water, food, as well as in the atmosphere ...

Microbiological water quality of the Nišava River
Microorganisms are the ideal indicators of the organic pollution of the surface waters because of their ability to promptly respond to environmental changes. Due to poor economic situation and lack of law implementation, most wastewaters in Serbia are released directly into a surface water recipient without any, or a limited, treatment. This practice has created numerous highly polluted ...
