Severn Trent goes natural at Hulland Ward

摘要

Hulland Ward Sewage Treatment Works (STW) in Derbyshire currently treats wastewater from a population of just under 900. Severn Trent Water has started work at the treatment works to replace a 50-year old conventional, biological filter works with a primary treatment system. Severn Trent Water is working in partnership with reed bed specialist ARM and construction firm MWH Treatment to install Phragmifiltres. Phragmifiltre, brought to the UK by ARM through its French partner EpurNature, is a vertical flow constructed wetland that has been successfully used as a primary treatment system throughout rural communities in France since the 1990s. Reed bed wastewater treatment systems are now widely being used worldwide for the full treatment of sewage through the application of the Phragmifiltre system.
