This research project was initiated to refine the knowledge available on the treatment of
municipal wastewater by combined anaerobic ponds and wetlands. To determine the
treatment capacity of combined system, a pilot scale of anaerobic ponds and subsurface
flow wetland was built and monitored over one treatment year. The anaerobic pond systems
consisted of two ponds: a) conventional pond and b) optimized pond that are combined with
two wetland cell units respectively. The conventional pond was built in common method and …
