Nitrogen Removal by a Combined Subsurface Vertical Down-Flow and Up-Flow Constructed Wetland Systemstem operated with higher HLR. The removal efficiency for NH.-N and COD was maximum at 10 cm day. (79 and 74% respectively). Nitrification was significant in vertical down-flow bed, denitrification in the up-flow bed at every HLR. The two-stage constructed wetland removed 96–98% of incoming total su

Factors Affecting the Longevity of Subsurface Horizontal flow Systems Operating as Tertiary Treatmereed beds have deteriorated to the extent that they are close to failing to comply with the regulator’s requirements. Severn Trent Water Ltd. recognised this situation and has committed a budget for a programme of reed bed maintenance. Initially a budget was allocated to refurbish the reed beds in t
