The benefits of monitoring compressed air

Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

Gas Detection and Monitoring Systems

In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

How to Monitor Mercury Emissions

In recent years, mercury levels in the environment and in the food chain have risen substantially mainly due to human activities. As a long-range pollutant it can affect areas located thousands of kilometers away from its original source of emission. It’s no wonder then that the regulatory pressure to monitor mercury emissions grows stronger. Before diving ...

Monitoring Environmental Quality

' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

Pollutant monitoring in sludge treatment wetlands

Phragmites australis for sludge dewatering and stabilization processes have been widely proved. The presence of reeds, indeed, efficiently allows solids dewatering and organic matter stabilization in order to obtain a stabilised product that can be suitable for land application, even if its environmental impact has to be considered. The actual revision of the European Union's Working Document on ...

RO monitors and Controllers: pros and cons

A look at a range of devices for watching TDS. One major question a potential customer may ask before they purchase a point-of-use/point-of-entry (POU/POE) water treatment system is, “How often will I need to change the filter?” Maintenance and service are directly related to two of their major concerns: money and health. People don’t want to spend money unnecessarily, yet they ...

An adaptive framework to differentiate receiving water quality impacts on a multi-scale level

The paradigm shift in recent years towards sustainable and coherent water resources management on a river basin scale has changed the subject of investigations to a multi-scale problem representing a great challenge for all actors participating in the management process. In this regard, planning engineers often face an inherent conflict to provide reliable decision support for complex questions ...

Multi-point monitoring of nitrous oxide emissions in three full-scale conventional activated sludge tanks in Europe

The large global warming potential of nitrous oxide (N2O) is currently of general concern for the water industry, especially in view of a new regulatory framework concerning the carbon footprint of water resource recovery facilities (WRRFs). N2O can be generated through different biological pathways and from different treatment steps of a WRRF. The use of generic emission factors (EF) ...
