Pressure and Level in Water Treatment - Mikael Leth Jensen

Having built more than 10,000 plants all over the world serving one billion people, Degrémont has proved itself without doubt to be an expert in the field of water treatment. The company develops and builds facilities such as drinking water production installations, desalination plants, waste water treatment and sewage sludge processing plants for local communities and industries. To ensure the efficient operation of its plants, Degrémont relies on the know-how and expertise of dedicated partners and suppliers. Digital devices such as TED50 and ED752 manufactured by Baumer (Switzerland) are used for pressure measurement and level detection.

Degrémont - an expert in water treatment
Degrément is a subsidiary of the French water and waste disposal group Suez Environnement. Since it was founded in Paris (France) back in 1939, the company has acquired extensive expertise in water processing and
treatment technologies. It is recognised all over the world as a reference in relation to the design, construction and delivery of turnkey installations. “Our main fields of expertise are waste water treatment, seawater desalination (reverse osmosis) and drinking water treatment. And of course, we also have know-how in the area of sewage sludge processing,” explains Patrick Descamps, engineer and instrumentation expert based at the company headquarters in Rueil-Malmaison (France). The Degrémont teams are capable of handling all the aspects of large-scale projects: operation, process optimisation, technical assistance and maintenance of the installations. Technical experts check, validate and approve the project and plant. “Therefore, our solutions must use reliable, state-of-the-art measuring instruments that are easy to parameterize and easy to adjust to the process requirements,” adds Descamps.

The advantages of digital instruments
When it comes to process instrumentation, analogue technology remains satisfactory for simple measuring or monitoring applications. For some years, Degrémont has been using Baumer’s mechanical instruments for measuring pressure and temperature. However, as soon as there is a need to transmit measurement data or to ensure a high and repeatable level of accuracy, switching to digital technology is crucial. “As soon as we consider it necessary, we replace our mechanical pressure gauges, pressure and temperature switches with electronic devices, which is why we turned to Baumer. Since Baumer’s mechanical instruments have been giving us full satisfaction for many years, it was natural for us to continue our cooperation with a reliable partner, capable of providing technical solutions in line with our requirements,” explains Patrick Descamps. “For instance, one single electronic pressure switch is now enough to perform the operations previously carried out by three separate devices, because the pressure switch has a built-in digital pressure gauge and pressure
transmitter.”
