Heathrow Airport( Mayfield Farm)

Constructed Wetlands: Groundwater Treatment Plants (GWT)

Created at: 25 Aug 2016

Description

Needs<br>Mayfield Farm Treatment Works,<br>commissioned in 2001 was designed to treat<br>run off from Heathrow Airport’s Southern<br>Catchment. The run off is contaminated with<br>glycols resulting from the airports de-icing<br>operations. Treating glycol contaminated<br>run off is a challenge at every airport faced<br>with varying cold-climate winter conditions.<br>The run off can contain over 20,000 mg COD/L at 1ºC.<br><br>The original system consisted of<br>balancing ponds, aeration lagoons, rafted<br>reed beds and 12 horizontal subsurface flow<br>reed beds covering 2.08 hectares. <br><br>Following trials ARM/Natturally Wallace upgraded the reed beds and lagoons using Forced Bed Aeration TM.<br><br>Solution<br>ARM/Naturally Wallace delivered a cost-effective treatment upgrade with increased system capacity and operational flexibility. System optimization minimized life<br>cycle costs for BAA.
