Leachate Treatment Plant - Warrington

In our case, put simply, Leachate is water that has been polluted by percolating through landfill rubbish.

PHOENIX have been involved with Leachate Treatment Plants since 1993. We have successfully completed 18 full plants. Many have been extended and upgraded during this period.

 

PHOENIX were contracted to undertake the entire electrical works. The project was completed in 2001.

Power was taken at 1250 amps from on-site generators. All design, installation and commissioning was carried out by PHOENIX.

The plant consists of two raw leachate balance tanks, three treatment tanks and a treated effluent balance tank. Discharge is then via  reed beds into the river Mersey. Two control rooms were built within shipping containers to house the four motor control centres and four SCADA PCs.

All controls are networked with site wide ethernet cabling enabling all plant to "talk" to each other.

This plant can treat 450m3 of Leachate per day.
