Bishopton Development - Wetland Treatment System

Wetland Treatment System 1

ByrneLooby assisted BAE Systems at their large Bishopton redevelopment site to manage a challenging effluent treatment problem using a 2,000 m2 reed bed and integrated leachate management system. Following design and construction, the system was commissioned via biological process and is now operational.

Our Role

As part of the remediation of this former munitions production site, contaminated soils were excavated and placed in a landfill. The leachate arising from the landfill is treated in a wetland system before discharge into the local surface water system. The design incorporated contingencies for any expansion of the landfill. Our plan included degrading leachable contaminants from a parallel soil washing pad before discharge into a nearby surface watercourse.

 

The integrated system adopted provides for a sustainable solution to deal with intermediate strength landfill leachates, where ammonia concentrations are below the average threshold for conventional treatment plants (<200 mg/l) but above that usually treated in reed beds (5 to 20 mg/l).
