Powelectrics IoT Middleware Enables Leachate Management on Landfill Sites

Posted on 01 Oct 2018

Powelectrics connected sensor technology is being used in a wide range of environmental applications, from waste oil collection and energy metering to flood monitoring. One area of growing interest is leachate management on landfill sites. Landfills are designed and operated to protect the environment from contaminants. As landfill waste degrades, rain filters through it and leads to the formation of leachate. This is generally a black liquid made up of chemicals, heavy metals and gases, which may be acidic, poisonous or even flammable.

Leachate is collected in impermeable liners beneath landfill areas and periodically pumped to holding tanks before being removed from site for safe processing. If the collection areas overfill and the leachate spills out of the liners, there is a risk to people, livestock and crops and groundwater may be contaminated.

For the project pictured here, our award-winning Metron2 telemetry unit was installed to take regular level readings with data reported to Powelectrics MetronView cloud. The IoT device is solar-powered, as no mains power was available and can report as frequently as every 10 minutes.

When the leachate reaches a user-defined ‘high’ level, the pump is activated. If the level continues to rise, indicating an issue with the pump, then site staff receive an alarm. This can be generated directly via MetronView, or some customers may use the simple MetronView API to interface with alarm despatch software. Once pumping has commenced and the level reaches the user-defined ‘low’ level, the pump is deactivated.

Now liners are emptied automatically, landfill management know how much leachate has been pumped to the holding tanks and they can also respond immediately if the pump appears to have failed.

Powelectrics telemetry is used in a wide range of Industry 4.0 remote level and condition monitoring applications. Remote monitoring devices are compatible with thousands of sensors offering a 4-20mA output. Within the landfill/pump station environment our Industry 4.0 technology may also be used to monitor pump failure, flow meters and levels in holding tanks.

Metron View is Powelectrics ‘middleware’, developed using an agile software development methodology, to offer rapid and flexible responses to specific existing and evolving application needs. It is a robust and proven, cloud-based data collection platform with customisable dashboards, bespoke reporting and user-defined alerts that are available to you wherever you have web access. Metron View is a truly ‘any network, any device’ solution, processing 2.5 million readings/day and supporting over 140 protocols including MODBUS, MQTT, HTTP, TCP, UDP, SERIAL, SIGFOX, SNMP. The simple API allows MetronView to provide services to your software applications (SaaS) beyond those available from your existing operating systems.

Powelectrics act as a connection between the world of sensors and the Industrial Internet of Things (IIoT) operating at the centre of the ‘connected sensor’ community. We offer 25 years’ experience in the world of sensors, our own award-winning telemetry devices, a standalone data platform and a wealth of experience integrating third party devices.
