Valmet to modernize waste water plant at LondonEnergy

07 February 2019

Valmet has signed a contract to modernize the automation systems as well as the electrical and instrumentation infrastructure of a waste water treatment plant for LondonEnergy Ltd. Located in North London, the plant is an essential part of LondonEnergy's operations for treatment of the collected waste streams from plant's various locations, allowing their discharge to the dedicated point.

The order was included in Valmet's third quarter of 2018 orders received. The modernization project is scheduled to be finalized during 2019.

Cooperation between the two companies started in 2012, when Valmet assisted LondonEnergy with five big boilers in their waste-to-energy facility by migrating the plant's obsolete PLC-based control to Valmet DNA. Initially, a multi-year plan was performed to update the control systems in the main boiler area while offering support services for legacy third-party equipment. A more recent project included improving the safety of LondonEnergy's steam turbines by using Valmet DNA-based vibration protection and analysis equipment.

The major challenge for the project is to perform the upgrade during normal operation, since uninterrupted functioning is critical for the processes of the entire facility. Therefore, changeover to the new controls must be completed seamlessly within a limited timeframe.
